Q&A: What does the health care law mean for you?

Chart shows voting record on the health care act

Chart shows voting record on the health care act

A small crowd applauds after listening to Tarrant County Democrats at the Tarrant County Public Health Department to show their support for President Barack Obama's health care overhaul on Thursday, June 28, 2012 in Fort Worth, Texas. The Supreme Court on Thursday upheld virtually all of President Barack Obama's historic health care overhaul, including the hotly debated core requirement that nearly every American have health insurance. The 5-4 decision meant the huge overhaul, still taking effect, could proceed and pick up momentum over the next several years, affecting the way that countless Americans receive and pay for their personal medical care.

(AP) ? Free vaccines for kids, cheaper drugs for the elderly and many other benefits of President Barack Obama's health care law are already out there. More are coming, like a guaranteed right to buy health insurance even for patients with serious medical troubles. Many businesses and wealthy taxpayers, however, will see their costs go up.

And most Americans balk at the idea of the government making people carry insurance or pay a penalty on their federal tax returns.

The effects of the nation's health care law, upheld Thursday by the Supreme Court, are gigantic and growing. Some questions and answers about it:

Q: What does the ruling mean for me?

A: The ruling affects virtually every American. Obama's health care law tells almost everyone they must be insured and makes sure that coverage will be available to them even if they are already ill or need hugely expensive care. It helps the poor and many middle-class people afford the cost. And it requires insurers to provide certain basic benefits, like preventive care without co-pays from the patient.

Q: What did the Supreme Court say?

A: The court upheld almost all of the law, including the most disputed part: the requirement that virtually all Americans have health insurance or pay a penalty. The court said the penalty is essentially a tax, and that's why the government has the power to impose it.

The ruling somewhat limits the plan to expand the Medicaid insurance program for the poor, a joint effort of the federal government and states. It says the government may not withhold a state's entire Medicaid allotment if it doesn't participate in the expansion.

Chief Justice John Roberts sided with the court's four liberal justices ? Stephen Breyer, Ruth Bader Ginsburg, Elena Kagan and Sonia Sotomayor ? to form the 5-4 majority.

Q: What does the decision mean for the November election?

A: It's a big win for Obama, dousing accusations that his signature legislation was an unconstitutional power grab. But Republicans hope the court's ruling will fire up their supporters and inflame popular opposition to the law.

Presumptive Republican presidential nominee Mitt Romney and GOP congressional candidates promise to repeal the law if voters put them in power.

Q: What's the law done so far?

A: Some parts, like the elimination of co-payments for preventive care, are already in effect. Young adults can stay on their parents' insurance up to age 26. Insurers can't deny coverage to children with health problems. Limits on how much policies will pay out to each person over a lifetime are eliminated. And millions of older people already are saving hundreds of dollars through improved Medicare prescription benefits.

Q: What else is coming?

A: Unless Congress changes the law, starting in 2014 almost everyone will be required to be insured or pay a penalty. Subsidies will help people who can't afford coverage. Most employers will face fines if they don't offer coverage for their workers. Newly created insurance markets will make it easier for individuals and small businesses to buy affordable coverage. And Medicaid will be expanded to cover more low-income people.

Insurers will be prohibited from denying coverage to people with medical problems or charging those people more. They won't be able to charge women more than men, either. During the transition to 2014, a special program for people with pre-existing health problems helps these people get coverage.

The law is expected to bring coverage to about 30 million of the estimated 50 million uninsured people in the U.S.

Overall, more than 9 in 10 of the eligible population ? citizens and legal residents ? will be covered.

Q: Why will some people still go without insurance?

A: It's estimated that more than 20 million people will still be without coverage, including illegal immigrants, people who don't sign up and choose to face the penalties instead and those who can't afford coverage even with the subsidies. That number could be higher, depending on whether any states decline the Medicaid expansion.

Q: Do people like the law?

Not much. Some parts of the law have proven popular. But the individual insurance mandate is widely disliked.

Each time The Associated Press has asked in polls, more than 8 in 10 Americans have said the government should not have the right to require everyone to buy health insurance.

And the public has tilted against the law as a whole over the two years since it was passed. About half opposed it and a third were in favor in an AP-GfK poll shortly before the Supreme Court ruled.

Many elderly Americans are worried about the cuts in reimbursements paid to hospitals and insurers by Medicare, which have already started and will grow deeper.

Q: Does the insurance mandate affect many people?

A: Relatively few, because more than 8 in 10 Americans already have insurance coverage.

Employers face their own mandate. Those with 50 or more workers will be fined if they don't provide insurance for their employees, and opponents argue that will cost jobs at a time of high unemployment.

Q: Why impose a mandate that's unpopular and won't require any action by most people?

A: The mandate is designed to produce extra income from more healthy, paying customers so insurers can to hold down costs for everyone. Without the mandate, insurance companies probably would find it too expensive to comply with requirements to accept customers with pre-existing health problems and not charge them extra. Companies sought to control their costs by cherry-picking the healthy as their customers.

Q: Is the penalty for the uninsured a tax?

A: It will be collected along with income tax each year by the Internal Revenue Service.

But Obama and Democrats have avoided using the dreaded "t-word." Instead, they referred to it as a penalty for failing to act responsibly and focused publicly on other legal justifications. Before the Supreme Court, however, the Obama administration also argued that the law was constitutional under the federal government's power to levy taxes.

The court rejected the Obama administration's other two legal arguments for the law but accepted the tax one.

Still, most of the 20 million or more without insurance will not be docked. By 2016, about 4 million people will pay the penalty, the Congressional Budget Office has estimated. They would pay $695 for each uninsured adult or 2.5 percent of family income, up to $12,500 a year.

The IRS can't prosecute violators or place liens against them, however. Its only enforcement option may be withholding money from refunds.

Q: What other new taxes are in the law?

A: An assortment, including: Individuals making more than $200,000 a year and couples earning above $250,000 will get new payroll taxes. These people are also hit with a 3.8 percent tax on investment income. Medical-device makers will pay a 2.3 percent excise tax, which probably will get passed along to patients. Taxpayers will have to spend more on unreimbursed medical care before they can claim itemized deductions.

Q: What are Republicans saying?

"Obamacare was bad law yesterday. It's bad law today," Romney said.

Senate Republican leader Mitch McConnell said Obama deceived Americans by denying that the penalty on the uninsured amounts to a tax. The ruling marks "a fresh start on the road to repeal," he declared.

The Republican-led House already has voted for repeal ? and its leaders plan to repeat that vote next month ? but repeal is stuck there so long as Obama's in the White House and Democrats lead the Senate.

Q: What does Obama say?

A: He says the decision upholds the fundamental principle that in the wealthiest nation on earth, no one should be ruined financially by an illness or accident. Obama called it "a victory for people all over this country whose lives will be more secure because of this law."

Q: If the law survives in Congress, will the health care issue finally be put to rest?

A: No, there's more to do. Although the law is supposed to help curb costs, the nation's spending on health care already is enormous and sure to climb as the baby boom generation ages.

Skyrocketing budget deficits will force lawmakers to look for ways to save on the Medicare program for seniors and Medicaid for the low-income and disabled, and that means painful choices ahead.

EUROPA - Press Releases - Mergers: Commission approves ...

European Commission

Press release

Brussels, 29 June 2012

Mergers: Commission approves acquisition of IBM's retail store solutions business by rival Toshiba

The European Commission has cleared under the EU Merger Regulation the proposed acquisition of IBM's retail store solutions business by Toshiba Tec, a majority owned subsidiary of the Japanese company Toshiba. Retail solutions are integrated systems of hardware and software that are used for processing sales transactions by retail store customers. They are capable of connecting and interoperating with a retailer?s other IT and software systems and are therefore distinguished from electronic cash registers. The Commission concluded that the transaction will not raise competition concerns because of the limited overlap between the parties' activities, in particular within the European Economic Area (EEA), and because the merged entity will face sufficient competition.

The proposed transaction would lead to an overlap between the parties' activities in the market for retail solutions, which includes point-of-sale (?POS?) systems, PC-on-cash-drawer (?PCCD") systems and self-service-systems. The Commission investigated the transaction's competitive effects on this overall product market as well as its possible sub-markets segmented by type of retail solutions (such as POS, PCCD, etc.) or customer segments (such as food retailers, convenience stores and petroleum outlets etc.).

The Commission's investigation found that the merged entity will continue to face substantial competition from several well-established, strong and effective competitors in the market(s) concerned. In addition, the investigation revealed that the parties were not each other's' closest competitors and that customers can easily switch suppliers.

The Commission therefore concluded that the transaction does not raise serious doubts as to its compatibility with the internal market and with the EEA Agreement.

The operation was notified to the Commission on 24 May 2012.

Companies and products

Toshiba is a diversified manufacturer, providing a wide range of products and services on a global basis in four business domains: digital products, electronic devices, social infrastructure and home appliances. Toshiba Tec falls within Toshiba?s digital products business domain and manufactures products and business solutions in four core areas: (i) retail solutions, (ii) office solutions, (iii) supply chain solutions and (iv) inkjet heads.

IBM is a U.S. public company active worldwide in the development, production, and marketing of a wide variety of information technology solutions. IBM's retail store solutions business is active within IBM's system and technology business segment and comprises the development and distribution of retail solutions, including POS systems, self-service-systems, and related maintenance and technical support services.

Merger control rules and procedures

The Commission has the duty to assess mergers and acquisitions involving companies with a turnover above certain thresholds (see Article 1 of the Merger Regulation) and to prevent concentrations that would significantly impede effective competition in the European Economic Area (EEA) or any substantial part of it.

The vast majority of mergers do not pose competition problems and are cleared after a routine review. From the moment a transaction is notified, the Commission generally has a total of 25 working days to decide whether to grant approval (Phase I) or to start an in-depth investigation (Phase II).

A non-confidential version of today's decision will be available at:

Executives Discover Innovative Leadership Solutions Via Venture ...

Posted on29 June 2012.

Executives who need to develop innovative leadership solutions should research creative financing sources when planning their new business, product or service strategies. Entrepreneurs don?t have to travel any further than their personal computer for news about raising venture capital funds.

Venture capital is one industry that has been around for the past 60 years or so. However, just like every other industry, it continues to evolve and change. Much of the VC industry?s success is due to the explosive growth of the Internet. The Web has made many information-gathering tasks faster and easier. Updates on venture capitalists and various kinds of venture capital news are readily accessible to the world?s citizens through online media.

Aside from the World Wide Web, there are other sources of venture capital news. Old, traditional sources such as newspapers and magazines continue to provide the necessary candidate criteria or details and information that venture capitalists and entrepreneurs need. These are also good sources of legal updates in the field of venture capital.

Information contributions by VC partners or research associates are published in paper periodicals, magazines or newspapers and can also be found on the Internet. Aside from the printed materials in circulation, some partners even write blogs and lens, operate their own websites and share their expertise in web-posted articles or ezines.

Newsletters and emails are also sources of news. Visitors to a VC-specific site will usually find offers for subscriptions to their daily or weekly newsletters. Inside these publications, sponsoring service providers empower entrepreneurs by providing them with useful articles and practical information. Additional contributions from business experts and capitalists can also be found in these news organs.

Discussion groups and forums are also good venues for posting updates. Online groups, bulletin boards, chatrooms and membership sites give you the ability to exchange ideas and interact with your fellow entrepreneurial colleagues.

Based on the quality and quantity of participants, you can gather advice or tips and learn innovative leadership solutions about the challenging aspects of financing your venture, from raising venture capital to the drafting of proposals to the design of your exit strategies.

Articles on venture capital are not limited to business pages or publications. There are websites which are specifically dedicated to venture capital ? these sites may post news stories or provide video streaming as well. News articles may be categorized into more specific topics such as buyout news, industry news, fund news and transition news.

When a site is classified into clearly defined sections, it makes it easier for the reader to choose which articles to read. So if you are interested in buyouts only, for example, then you don?t have to plow through all articles to find the information that you want. It also helps to have the articles arranged by date, to allow the reader the means to assign currency or relevance to the piece.

With the Internet being worldwide in scope, articles, papers and even application forms can be accessed by practically anyone anywhere, in the same way that we read news, visit offices and updates in our own countries. Everyone with web access can find ways to tap into the innovative leadership solutions being provided by venture capitalist firms.

This goes to show that the availability of venture capital is a worldwide phenomenon. However, in the US alone, close to $29.9 Billion was used for venture capital investment in 2007.

Today?s capitalists are no longer restricted to the US markets only but can now consider funding companies and businesses in China, India and other developing countries in Asia, the Pacific Rim or Middle East and Africa. This is good news for countries in these regions with vast manpower resources but limited access to equity funding.

Entrepreneurial executives can be better informed about the latest trends in VC. Last year, the trend was towards early stage investing. It was estimated that 35% of VC investments will go to seed-stage and early stage deals. On the other hand, expansion-stage funding showed signs of being decreased.

There are some really good websites which provide venture capital news and more. Aside from news, they also provide listings of venture capital firms and the companies that they helped fund.

Find these websites and bookmark them. For entrepreneurs, these sites provide the useful, innovative leadership solutions they need to learn more about the venture capitalist arena.

Family tragedy becomes public when death video hits Twitter

2 hrs.

By the time police asked Internet users to remove graphic photos of a man decapitated after he jumped in front of a train, it was too late for the dead man's son. He had already seen the grisly images ? recorded by teenagers?just after the incident occurred ? when they went viral on Twitter.

You can hear the teens in the background of the shaky cellphone video, recorded Wednesday afternoon in the Netherlands, calling to each other in Dutch, their adolescent voices tweaked with shock, excitement. "Here. Here is the body. Here he is," one boy shouts in Dutch. Another points to the man's severed head, a few feet away. No one is laughing.?

At least 70 students?at a nearby school ??in the?Kennemerland area of?Haarlem ??witnessed the accident or immediate aftermath, reports?Ijmuider Courant, a Netherlands news site. School officials swung into action. Within 10 minutes of the incident,?administrators?guided students away from the station and back to the school. There, counselors and members of the?Kennemerland police department spent the afternoon talking to kids and later, their parents, about what they had seen.

Yet at the same time that the school was trying to mitigate the psychological damage of the incident, a video of it was being shared among students and?making its way out onto the Internet, by way of Twitter.

This is the video the?dead man's son had already seen when?Kennemerland?police broke the news to the family. It was then that son connected the two, and realized the video was of his father.?

When the police department found out about the video, the department took to Twitter and asked the public to stop sharing the video. In Dutch, the police?asked, "Anyone who has shared pictures of the?Driehuis?train victim, remove them immediately. It is disrespectful and goes too far!"

It's a good-faith plea, made by a police department savvy in the ways of the Internet, enough to know it was already too late. It was too late 15 minutes after the video first hit Twitter, when the teenage boy who first sent it out into cyberspace deleted his original tweet. It had already been?retweeted countless times. And that is the lesson that Evy Elschot, spokesperson for the Kennemerland police department, hopes people will take away from this incident, instead of the gory details.

"The boy didn't understand the impact of what he had done," Elschot told msnbc.com in a telephone interview. Identifying him only as a teenager between the ages of 14 and 16, Elschot described him choking on tears and shaking with panic when confronted by police. "The boy said he wished he didn't do it, that he could take it back, but of course he couldn't," she said.

The boy tweeted (in Dutch), "I hate myself for what I've done," according to news site RTL.?

Elschot told msnbc.com she regrets the story receiving national attention, resulting in?the inevitable spread of a video that causes pain to a family already suffering. (Msnbc.com will not link to the video.) To protect the family's privacy, she would not share the age of the son who saw his father in the video.?

According to?Elschot, it was a very difficult decision to ask people via Twitter to delete the video.

The Kennemerland police department is very active on Twitter, using the official account to communicate with the public on such things as traffic delays, especially crowded areas at festivals, as well as finding witnesses to crimes and fielding complaints (and compliments) from the public. But by using Twitter to discuss a suicide, the Kennemerland police department went against what Elschot describes as Holland's "gentleman's agreement" to not publicize details about suicides.

Elschot said that it's in consideration for families whose?members?commit suicide,?but this practice also abides by the World Health Organization's recommendations for avoiding suicide contagion ? a phenomenon which affects those already at risk. Train suicides account for 4 to 10 percent of suicides in the Netherlands, the Journal of Affective Disorders reported in 2010.??Such a video going viral could spread contagion as well.

Elschot agrees that there's an important discussion to be had, but not about this family's tragedy.

"This really is about young people and how the world is different," she said. "When I was a kid, I might say some things in my small town without thinking, but we only had the telephone. Someone else might read your letter, and there is embarrassment for awhile, but not the oil spread of information we now have on the Internet. Kids need to understand that and their parents need to tell them."

The American Library Association website offers a variety of resources to help parents and kids navigate the Internet safely and responsibly. ?

If you are thinking about harming yourself or attempting suicide, tell someone who can help right away:

  • Call your doctor?s office.
  • Call 911 for emergency services.
  • Go to the nearest hospital emergency room.
  • Visit the website or call the toll-free, 24-hour hotline of the National Suicide Prevention Lifeline at?1-800-273-TALK (1-800-273-8255)?to be connected to a trained counselor at a suicide crisis center nearest you.

Ask a family member or friend to help you make these calls or take you to the hospital.

Quebec, California to link their cap-and-trade carbon programs

MONTREAL - Quebec remains confident that it and California will link their cap-and-trade carbon programs despite a delayed vote on the issue, sustainable development minister Pierre Arcand said.

?Quebec and the State of California are intensifying their collaboration to have a common first auction in early 2013,? Arcand said Friday.

Earlier in the week, California regulators delayed a vote on rules that would link the state?s cap-and-trade program with Quebec?s and allow companies to trade carbon permits across borders.

The California Air Resources Board put off the vote to request approval from the governor to comply with a new law that requires him to review and accept such an agreement.

Should the programs join, companies could use carbon permits issued as part of Quebec?s cap-and-trade program to comply with California?s greenhouse-gas regulations.

The California board intends to demonstrate that Quebec regulations are at least as strict as those of the state, Arcand said.

California Governor Jerry Brown will have 45 days to submit findings on the proposal to link programs with Quebec.

The air board?s staff has recommended linking programs with Quebec to strengthen the market for carbon permits and drive down emissions by larger volumes.

?I can well understand the challenges facing California lawmakers, and I am confident that the Governor?s report will show that the two regulations have similar requirements,? Arcand said.

?In the meantime, we are actively pursuing our commitment to the implementation of the carbon market through our cooperation with the State of California and other partners in the Western Climate Initiative.?

Regulators in both Quebec and California will issue carbon permits, each allowing for the release of one metric tonne, through a combination of free allocations and auctions. Companies must turn in carbon permits beginning next year to cover their emissions, and those under the shrinking cap can sell or trade their permits.

California is scheduled to hold its first auction of permits on Nov. 14.

Quebec, along with California, which established a carbon program after U.S. legislators declined to develop a federal one, will join more than 30 governments operating emissions-trading programs worldwide next year in 27 European Union member states, Switzerland and New Zealand.

At least eight other jurisdictions, including Mexico and Indonesia, are considering programs.

In Quebec, the program is a major component in the province?s bid to reduce greenhouse gas emissions to 20 per cent below 1990 levels by 2020.

Part of the genome of two hunter-gatherers from 7,000 years ago

ScienceDaily (June 28, 2012) ? A team of scientists, led by researcher Carles Lalueza-Fox from CSIC (Spanish National Research Council), has recovered -- for the first time in history -- part of the genome of two individuals who were alive in the Mesolithic Period, 7000 years ago.? The remains were found at La Bra?a-Arintero site, located at Valdelugueros (Le?n), Spain.

The study results, published in the Current Biology, indicate that current Iberian populations do not come from these recently discovered humans.

The Mesolithic Period, framed between the Paleolithic and Neolithic Periods, is characterized by the advent of agriculture, coming from the Middle East.

The genome found is the oldest from Prehistory, 1,700 years before ?tzi, the Iceman lived.

Researchers have also recovered the complete mitochondrial DNA of one of these individuals, through which they could determine that European populations from Mesolithic Period were very uniform genetically. Carles Lauleza-Fox, from the Institute of Evolutionary Biology (CSIC-UPF), states: "These hunters-gatherers shared nomadic habits and had a common origin. Despite their geographical distance, individuals from the regions corresponding to the current England, Germany, Lithuania, Poland, and Spain, shared the same mitochondrial lineage."

The DNA data, which represent the 1.34% and the 0.5% of both individuals total genome, show that they are not directly connected to current populations of the Iberian Peninsula. Iberians from the Mesolithic Period were closer to current populations of northern Europe, who could have assimilated part of the genetic legacy of these hunters-gatherers.

La Bra?a-Arintero site was discovered in 2006 by chance. Juan Manuel Vidal Encinas, archeologist from the Regional Government of Castilla y Le?n, who has also participated in the study, has excavated it at a later date. The cave, due to its location in a cold and mountainous area, is a suitable place for the good preservation of the DNA of these two individuals, found inside it.

The oldest remains from Prehistory

CSIC researcher emphasizes: "So far, we only had one genome of the European Prehistory, that of ?tzi [also known as the Iceman], from the Neolithic Period. His mummy, belonging to a man who lived 5300 years ago, was found in the Tyrolean Alps, on the border between Austria and Italy. La Bra?a-Arintero site offers a unique opportunity to obtain pre-Neolithic genomes."

According to Lalueza-Fox, this is only a first result since the intention of the team is to recover the complete DNA of these individuals, and to compare it with that of the modern humans. CSIC researcher discloses: "The arrival of the Neolithic Period brought about a replacement of populations, and could cause genetic changes in genes associated with new infectious diseases, and in metabolic genes linked to changes in diet. Therefore, all the information extracted from this genome will be absolutely important."

Physical Activity, Academic Performance and Cognition in Children and Adolescents. A Systematic Review

Type Journal Article
Author Eero Haapala
Abstract A literature review was conducted to investigate the effect of physical exercise and physical training on cognition and academic performance in children and adolescents. Nine randomized or quasi-randomized controlled trials with 2,013 participants were identified by employing the following data sources: the Cochrane Register of Controlled Trials, Medline, Eric, CINAHL, PsychINFO, and ISI Web of Knowledge. Five studies indicated positive effects of physical exercise on attention, concentration, and working memory, and three studies reported positive effects of 14 to 64 week physical training on language and arithmetic skills. Thus, there is some evidence that physical exercise may facilitate cognitive functions related to learning and enhance academic performance.

Academic achievement in relation to improved physical activity

Type Web Page
Author Cassie Duff
Abstract INTRODUCTION: According to the Center for Disease Control and Prevention, children and adolescents require 60 minutes or more of physical activity per day. In 2006, only 3.8 percent of elementary schools, 7.9 percent of middle schools, and 2.1 percent of high schools offered students daily physical education or its equivalent for the entire school year. Research shows that keeping physical education programs does not have an adverse effect on academics. This research study was conducted to see how adding the recommended daily physical activity would affect academic achievement. PURPOSE: The purpose of this study was to determine whether improved physical activity had an adverse effect on academic achievement. METHODS: 14 subjects began the study and only 13 subject completed post testing. Four women (16 yrs) and nine men (16 yrs) were high school students at Burton Adventist Academy and volunteered to participate in this study. Each subject participated in a 3 month physical education class. At the beginning of the class each subject performed the exercise testing included in the fitnessgram (push up test, curl up test, 2 site skinfold, and sit and reach). Each subject also then took an academic test, which was taken from a sample SAT prep booklet. At the end of the class each subject performed another fitnessgram and took another academic test. RESULTS: There was a statistically significant difference in the push up test (pretest, 35.08 ? 10.54; posttest, 40.92 ? 9.93; P= 0.02), curl up test (pretest, 34.8 ? 6.71; posttest, 41.69 ? 8.65; P= 0.04), and in the sit and reach (pretest, 21.15 ? 6.93; posttest, 24.85 ? 5.96; P= 0.01). In terms of the 2 site skinfold (pretest arm, 15.31 ? 5.61; posttest arm, 15.41 ? 4.34; pretest thigh, 22.54 ?8.8; posttest thigh, 23.08 ? 5.46; P>0.05) and academic test (pretest, 27.23 ? 6.98; posttest, 30.00 ? 8; P>0.05) no significant difference was observed. CONCLUSION: The results from this study indicate that with improved physical fitness there was no adverse effect on academic achievement.

Physical Activity and Performance at School: A Systematic Review of the Literature Including a Methodological Quality Assessment

Type Web Page
Author Amika Singh
Abstract Objective: To describe the prospective relationship between physical activity and academic performance. Data Sources: Prospective studies were identified from searches in PubMed, PsycINFO, Cochrane Central, and Sportdiscus from 1990 through 2010. Study Selection: We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data. Main Exposure: Studies had to report at least 1 physical activity or physical fitness measurement during childhood or adolescence. Main Outcome Measures: Studies had to report at least 1 academic performance or cognition measure during childhood or adolescence. Results: We identified 10 observational and 4 intervention studies. The quality score of the studies ranged from 22% to 75%. Two studies were scored as high quality. Methodological quality scores were particularly low for the reliability and validity of the measurement instruments. Based on the results of the best-evidence synthesis, we found evidence of a significant longitudinal positive relationship between physical activity and academic performance. Conclusions: Participation in physical activity is positively related to academic performance in children. Because we found only 2 high-quality studies, future high-quality studies are needed to confirm our findings.These studies should thoroughly examine the dose-response relationship between physical activity and academic performance as well as explanatory mechanisms for this relationship.

A review of chronic and acute physical activity participation on neuroelectric measures of brain health and cognition during childhood

Type Journal Article
Author Charles H Hillman
Author Keita Kamijo
Author Mark Scudder
Abstract BACKGROUND A growing body of research has detailed the beneficial relation of chronic participation in--and acute responses to--physical activity on aspects of cognition that underlie scholastic achievement. Here, we review the relevant neuroelectric findings on this beneficial relation in children, providing support for the influence of physical activity on specific cognitive processes that comprise academic performance. METHOD A review of studies examining physical activity and neuroelectric concomitants of cognition during childhood is described. When applicable, research involving adult populations is also described to better inform on this relationship in children. RESULTS Collectively, the data support a beneficial relation of chronic and acute participation in physical activity to brain health and cognition. The results suggest more effective allocation of cognitive processes involved in stimulus engagement and action monitoring during tasks requiring variable amounts of cognitive control in children. CONCLUSION Physical activity may influence brain health and cognition in children, leading to enhanced scholastic performance and greater overall effective functioning across the lifespan.

Physical activity interventions and children's mental function: An introduction and overview

Type Journal Article
Author Phillip D. Tomporowski
Author Kate Lambourne
Author Michelle S. Okumura
Abstract Background
This review provides a historical overview of physical activity interventions designed by American educators and an evaluation of research that has assessed the effects of exercise on children's mental function.
Method
Historical descriptions of the emergence of American physical education doctrine throughout the 20th century were evaluated. Prior reviews of studies that assessed the effects of single acute bouts of exercise and the effects of chronic exercise training on children's mental function were examined and the results of recent studies were summarized.
Results
Physical activity interventions designed for American children have reflected two competing views: activities should promote physical fitness and activities should promote social, emotional, and intellectual development. Research results indicate that exercise fosters the emergence of children's mental function; particularly executive functioning. The route by which physical activity impacts mental functioning is complex and is likely moderated by several variables, including physical fitness level, health status, and numerous psycho-social factors.
Conclusion
Physical activity interventions for children should be designed to meet multiple objectives; e.g., optimize physical fitness, promote health-related behaviors that offset obesity, and facilitate mental development.

Physically active academic lessons in elementary children

Type Journal Article
Author John B. Bartholomew
Author Esbelle M. Jowers
Abstract Background Although schools are an ideal location to conduct interventions that target children, the emphasis on standardized testing makes it difficult to implement interventions that do not directly support academic instruction. In response, physically active academic lessons have been developed as a strategy to increase physical activity while also addressing core educational goals. Texas I-CAN! is one incarnation of this approach. Methods We will review on-going research on the impact of these active lessons on: teacher implementation, child step count, child attention control, and academic performance. Results The collected studies support the impact of physically active academic lessons on each area of interest. Conclusions If these data can be replicated, it suggests that teachers might find these lessons of benefit to their primary role as educators, which should ease dissemination of these and other physically active lessons in elementary schools.

Associations between Health-Related Physical Fitness, Academic Achievement and Selected Academic Behaviors of Elementary and Middle School Students in the State of Mississippi

Type Journal Article
Author Lindsey Blom
Abstract A wide variety of school-based physical activity contexts have been recently associated with various measures of academic performance. Of these studies, a small number employing objective measures of student fitness have identified a relationship with academic achievements. However, even among these studies, the fitness-academic link has not been conclusively recognized or regularly assessed with regards to academic behaviors and socio-demographic variables. The purpose of this study was to explore the relationships among these variables by using objective measures of fitness, standardized Language Arts and Math test scores, attendance records, discipline actions, and socio-demographic information from a sample of 2,992 Mississippi (USA) public school children in grades 3-8. The sample consisted of students who were mostly male (52.4%), white (52.3%), in grades 3-5 (64.2%), within a healthy weight range (54.1%), and qualified for free/reduced price lunch (63.7%). The results indicated a statistically significant positive correlation between fitness and standardized test scores in Language Arts and Math and a statistically significant negative relationship with school absences. The relationships remained significant while controlling for gender, race, and socioeconomic status. Given that students who were more fit had higher test scores and fewer absences, these findings warrant consideration in the educational policy making process.

Classroom-based physical activity, cognition, and academic achievement

Type Web Page
Author Joseph Donnelly
Abstract Background. There is increasing evidence for the association between physical activity, cardiovascular fitness, fatness, and cognitive function during childhood and adolescence. Evidence also suggests that these variables are linked to academic achievement. Classroom-based physical activity provides a viable approach to improve fitness, body mass index (BMI), cognitive function, and ultimately academic achievement. Methods. Studies examining the relation between physical activity, fitness, fatness, cognitive function, and academic achievement are described. The results of a large-scale, longitudinal, cluster randomized trial to examine the impact of classroom based physical activity on body mass index and academic achievement will be presented. Results. Overall, the data support the link between physical activity, cognitive function, and academic achievement. The role of physical activity in the classroom was also supported by the Physical Activity Across the Curriculum (PAAC) project. Physically active academic lessons of moderate intensity improved overall performance on a standardized test of academic achievement by 6% compared to a decrease of 1% for controls (pb0.02). Body mass index increased less from baseline to 3 years in students with greater than 75 minutes of PAAC lessons per week (1.8 BMI) compared to students with less than 75 minutes of PAAC per week (2.4 BMI), pb0.00. Conclusions. Future research examining the effects of physically active academic instruction is warranted. The impact of physically active academic lessons of greater intensity may provide larger benefits for body mass index and academic achievement.

Ten Years of TAKE 10!?: Integrating physical activity with academic concepts in elementary school classrooms

Type Web Page
Author Debra Kibbe
Abstract Objective. Current literature supports the link between physical activity (PA) or fitness and a child's ability to achieve academically; however, little structured activity time is incorporated into elementary school classrooms. This paper explores the impact of a classroom-based PA program, TAKE 10!, and health?academic integration through existing state and federal policy and programming. Methods. Evidence from journal articles, published abstracts, and reports were examined to summarize the impact of TAKE 10! on student health and other outcomes. This paper reviews 10 years of TAKE 10! studies and makes recommendations for future research. Results. Teachers are willing and able to implement classroom-based PA integrated with grade-specific lessons (4.2 days/wk). Children participating in the TAKE 10! program experience higher PA levels (13%>), reduced time-off-task (20.5%), and improved reading, math, spelling and composite scores (pb0.01). Furthermore, students achieved moderate energy expenditure levels (6.16 to 6.42 METs) and studies suggest that BMI may be positively impacted (decreases in BMI z score over 2 years [Pb0.01]). Conclusion. TAKE 10! demonstrates that integrating movement with academics in elementary school classrooms is feasible, helps students focus on learning, and enables them to realize improved PA levels while also helping schools achieve wellness policies.

A Narrative Review of Physical Activity, Nutrition, and Obesity to Cognition and Scholastic Performance across the Human Lifespan

Type Web Page
Author Toni Burkhalter
Abstract We reviewed studies that examine the relationship of energy consumption, storage, and expenditure to cognition and scholastic performance. Specifically, the literature base on nutrient intake, body mass, and physical activity is described relative to cognitive development and academic achievement. The review of literature regarding the overconsumption of energy and excess body mass suggests poorer academic achievement during development and greater decay of brain structure and function accompanied by increased cognitive aging during older adulthood. The review of literature regarding energy expenditure through the adoption of increased physical activity participation suggests increased cognitive health and function. Although this area of study is in its infancy, the preliminary data are promising and matched with the declining physical health of industrialized nations; this area of science could provide insight aimed at improving brain health and cognitive function across the human lifespan.

Exercise Improves Executive Function and Achievement and Alters Brain Activation in Overweight Children: A Randomized, Controlled Trial

Type Journal Article
Author Catherine Davis
Abstract Objective: This experiment tested the hypothesis that exercise would improve executive function. Design: Sedentary, overweight 7- to 11-year-old children (N ? 171, 56% girls, 61% Black, M ? SD age ? 9.3 ? 1.0 years, body mass index [BMI] ? 26 ? 4.6 kg/m2, BMI z-score ? 2.1 ? 0.4) were randomized to 13 ? 1.6 weeks of an exercise program (20 or 40 min/day), or a control condition. Main Outcome Measures: Blinded, standardized psychological evaluations (Cognitive Assessment System and Woodcock-Johnson Tests of Achievement III) assessed cognition and academic achievement. Functional MRI measured brain activity during executive function tasks. Results: Intent to treat analysis revealed dose-response benefits of exercise on executive function and mathematics achievement. Preliminary evidence of increased bilateral prefrontal cortex activity and reduced bilateral posterior parietal cortex activity attributable to exercise was also observed. Conclusion: Consistent with results obtained in older adults, a specific improvement on executive function and brain activation changes attributable to exercise were observed. The cognitive and achievement results add evidence of dose-response and extend experimental evidence into childhood. This study provides information on an educational outcome. Besides its importance for maintaining weight and reducing health risks during a childhood obesity epidemic, physical activity may prove to be a simple, important method of enhancing aspects of children?s mental functioning that are central to cognitive development. This information may persuade educators to implement vigorous physical activity.

Low Aerobic Fitness and Obesity Are Associated with Lower Standardized Test Scores in Children

Type Journal Article
Author Christian K. Roberts
Author Benjamin Freed
Author William J. McCarthy
Abstract

Objective
To investigate whether aerobic fitness and obesity in school children are associated with standardized test performance.
Study design
Ethnically diverse (n = 1989) 5th, 7th, and 9th graders attending California schools comprised the sample. Aerobic fitness was determined by a 1-mile run/walk test; body mass index (BMI) was obtained from state-mandated measurements. California standardized test scores were obtained from the school district.
Results
Students whose mile run/walk times exceeded California Fitnessgram standards or whose BMI exceeded Centers for Disease Control sex- and age-specific body weight standards scored lower on California standardized math, reading, and language tests than students with desirable BMI status or fitness level, even after controlling for parent education among other covariates. Ethnic differences in standardized test scores were consistent with ethnic differences in obesity status and aerobic fitness. BMI-for-age was no longer a significant multivariate predictor when covariates included fitness level.
Conclusions
Low aerobic fitness is common among youth and varies among ethnic groups, and aerobic fitness level predicts performance on standardized tests across ethnic groups. More research is needed to uncover the physiological mechanisms by which aerobic fitness may contribute to performance on standardized academic tests.

Abstract Little is known, about the influence of different exercise intensities on cognition, the concentration of steroid hormones (SHs), and their interaction in adolescents. Sixty high school students from the 9th grade were randomly assigned to two experimental (EG 1, EG 2) and a control group (CG). Saliva collection took place after a normal school lesson (t1) and after a 12-min resting control or exercise (t2) in a defined heart rate (HR) interval (EG 1: 50-65% HR max, n=18; EG 2: 70-85% HR max, n=20; CG: no intervention, n=21). Saliva was analyzed for T and C. Cognitive performance was assessed using a working memory task (Letter Digit Span; LDS), which took place after t1 and t2. Repeated measure ANOVAs revealed a significant group by test interaction, indicating an increase of C and T level only for EG 2. Results for LDS showed a significant improvement due to exercise when groups were split into low and high performer at pre-test with a higher improvement of the low performers. In addition, post-test T levels negatively correlated with changes in LDS performance in EG 2. The results indicate that the concentrations of C and T are intensity dependent, and that exercise improves working memory in low performing adolescents. Only increased T, however, seems to be related to pre-to-post-test changes in working memory by having a detrimental effect on performance.

Physical Activity and Sports Team Participation: Associations With Academic Outcomes in Middle School and High School Students

Type Journal Article
Author Claudia K. Fox
Author Daheia Barr-Anderson
Author Dianne Neumark-Sztainer
Author Melanie Wall
Abstract BACKGROUND: Previous studies have found that higher physical activity levels are associated with greater academic achievement among students. However, it remains unclear whether associations are due to the physical activity itself or sports team participation, which may involve requirements for maintaining certain grades, for example. The purpose of this study is to examine the associations between sports team participation, physical activity, and academic outcomes in middle and high school students.
METHODS: Data were drawn from Project EAT (Eating Among Teens), a survey of middle and high school students (n = 4746). Students self-reported their weekly hours of physical activity, sports team participation, and academic letter grades. Two statistical models were considered: first, 2 separate regression analyses with grade point average (GPA) as the outcome and either sports team participation or physical activity as the predictor; second, a single regression with GPA as the outcome and both sports team participation and physical activity as the simultaneous predictors.
RESULTS: For high school girls, both physical activity and sports team participation were each independently associated with a higher GPA. For high school boys, only sports team participation was independently associated with a higher GPA. For middle school students, the positive association between physical activity and GPA could not be separated from the relationship between sports team participation and a higher GPA.
CONCLUSIONS: Regardless of whether academic success was related to the physical activity itself or to participation on sports teams, findings indicated positive associations between physical activity involvement and academic achievement among students.

Effect of a Two-Year Obesity Prevention Intervention on Percentile Changes in Body Mass Index and Academic Performance in Low-Income Elementary School Children

Type Journal Article
Author Danielle Hollar
Abstract Objectives. We assessed the effects of a school-based obesity prevention intervention that included dietary, curricula, and physical activity components on body mass index (BMI) percentiles and academic performance among low income elementary school children. Methods. The study had a quasi-experimental design (4 intervention schools and 1 control school; 4588 schoolchildren; 48% Hispanic) and was conducted over a 2-year period. Data are presented for the subset of the cohort who qualified for free or reduced-price school lunches (68% Hispanic; n=1197). Demographic and anthropometric data were collected in the fall and spring of each year, and academic data were collected at the end of each year. Results. Significantly more intervention than control children stayed within normal BMI percentile ranges both years (P=.02). Although not significantly so, more obese children in the intervention (4.4%) than in the control (2.5%) decreased their BMI percentiles. Overall, intervention schoolchildren had significantly higher math scores both years (P<.001). Hispanic and White intervention schoolchildren were significantly more likely to have higher math scores (P<.001). Although not significantly so, intervention schoolchildren had higher reading scores both years. Conclusions. School-based interventions can improve health and academic performance among low-income schoolchildren

Abstract During early adulthood, a phase in which the central nervous system displays considerable plasticity and in which important cognitive traits are shaped, the effects of exercise on cognition remain poorly understood. We performed a cohort study of all Swedish men born in 1950 through 1976 who were enlisted for military service at age 18 (N = 1,221,727). Of these, 268,496 were full-sibling pairs, 3,147 twin pairs, and 1,432 monozygotic twin pairs. Physical fitness and intelligence performance data were collected during conscription examinations and linked with other national databases for information on school achievement, socioeconomic status, and sibship. Relationships between cardiovascular fitness and intelligence at age 18 were evaluated by linear models in the total cohort and in subgroups of full-sibling pairs and twin pairs. Cardiovascular fitness, as measured by ergometer cycling, positively associated with intelligence after adjusting for relevant confounders (regression coefficient b = 0.172; 95% CI, 0.168?0.176). Similar results were obtained within monozygotic twin pairs. In contrast, muscle strength was not associated with cognitive performance. Cross-twin cross-trait analyses showed that the associations were primarily explained by individual specific, non-shared environmental influences (?80%), whereas heritability explained <15% of covariation. Cardiovascular fitness changes between age 15 and 18 y predicted cognitive performance at 18 y. Cox proportional-hazards models showed that cardiovascular fitness at age 18 y predicted educational achievements later in life. These data substantiate that physical exercise could be an important instrument for public health initiatives to optimize educational achievements, cognitive performance, as well as disease prevention at the society level.

Physical fitness, but not acute exercise modulates event-related potential indices for executive control in healthy adolescents

Type Journal Article

Author R?diger Heim
Author Markus Kiefer
Abstract Physical activity and aerobic exercise in particular, promotes health and effective cognitive functioning. To elucidate mechanisms underlying the beneficial effects of physical fitness and acute exercise, behavioral and electrophysiological indices of task preparation and response inhibition as a part of executive functions were assessed in a modified version of an Eriksen flanker task subsequent to an acute bout of aerobic exercise and a period of rest, respectively. 35 higher- and lower-fit adolescents between 13 and 14 years of age participated in a controlled cross-over study design. Results indicate that higher-fit individuals show significantly greater CNV amplitudes, reflecting enhanced task preparation processes, as well as decreased amplitudes in N2, indexing more efficient executive control processes. P3 amplitudes associated with the allocation of attentional and memory control neither showed influences of physical fitness nor the acute bout of exercise. Furthermore, acute aerobic exercise was not related to any of the dependent measures. The current findings suggest that physical fitness, but not an acute bout of aerobic exercise enhances cognitive processing by increasing attentional allocation to stimulus encoding during task preparation.

Author A.F. Kramer
Abstract The effect of an acute bout of moderate treadmill walking on behavioral and neuroelectric indices of the cognitive control of attention and applied aspects of cognition involved in school-based academic performance were assessed. A within-subjects design included twenty preadolescent participants (Age = 9.5 ? 0.5 years; 8 female) to assess exercise-induced changes in performance during a modified flanker task and the Wide Range Achievement Test 3. The resting session consisted of cognitive testing followed by a cardiorespiratory fitness assessment to determine aerobic fitness. The exercise session consisted of 20 minutes of walking on a motor-driven treadmill at 60% of estimated maximum heart rate followed by cognitive testing once heart rate returned to within 10% of pre-exercise levels. Results indicated an improvement in response accuracy, larger P3 amplitude, and better performance on the academic achievement test following aerobic exercise relative to the resting session. Collectively, these findings indicate that single, acute bouts of moderately-intense aerobic exercise (i.e., walking) may improve the cognitive control of attention in preadolescent children, and further supports the use of moderate acute exercise as a contributing factor for increasing attention and academic performance. These data suggest that single bouts of exercise affect specific underlying processes that support cognitive health and may be necessary for effective functioning across the lifespan.

Relationships of Physical Activity to Brain Health and the Academic Performance of Schoolchildren.pdf

Type Web Page
Author Fran?ois Trudeau
Author Roy Shephard
Abstract This review examines possible relationships between academic performance and participation in sports, physical education, and other forms of physical activity. Recent fundamental research has reignited interest in the effects of physical activity on cognitive processes. Experimental studies of potential mediating variables point to physiological influences such as greater arousal and an increased secretion of neurotrophins and psychosocial influences such as increased self-esteem and connectedness to schools. In the specific case of sports, experimental studies are limited to demonstrations of greater attention and acute gains of mental performance immediately following such activity. Several quasi- experimental studies of other types of physical activity have been completed, mainly in primary school students; these have found no decrease in academic performance despite a curtailing of the time allocated to the teaching of academic subjects. Indeed, in some cases, experimental students undertaking more physical activity have outperformed control students. Many investigators have looked at crosssectional associations between participation in sport or other forms of physical activity and academic performance. Despite difficulties in allowing for confounding variables, particularly socioeconomic status, the overall conclusion has been of a weak positive association. From the practical point of view, it can be concluded that the physical activity needed for healthy child development can be incorporated into the school curriculum without detriment to academic achievement.

The effect of acute physical exercise on cognitive function during development

Type Journal Article
Author Dave Ellemberg
Abstract Although accumulating research suggests that acutephysicalexercise ameliorates cognitivefunction in adults, little is known about the effects of acuteexercise on cognition during development. We assessed simple reaction and choice response times in 7- and 10-year-old boys (n = 36 per age group). Half of the children completed 30 min of aerobic exercise, whilst the other half watched television. Each child was tested immediately prior to and immediately following the intervention. Compared to the control group, the children in the exercise condition showed a significant improvement on both tasks, with a better outcome for the choice compared to the simple task. These findings indicate that physicalexercise also has an impact on cognitive functioning in children.

Acute coordinative exercise improves attentional performance in adolescents

Author G?nter Tidow
Abstract Teachers complain about growing concentration deficits and reduced attention in adolescents. Exercise has been shown to positively affect cognitive performance. Due to the neuronal connection between the cerebellum and the frontal cortex, we hypothesized that cognitive performance might be influenced by bilateral coordinative exercise (CE) and that its effect on cognition might be already visible after short bouts of exercise. One hundred and fifteen healthy adolescents aged 13-16 years of an elite performance school were randomly assigned to an experimental and a control group and tested using the d2-test, a test of attention and concentration. Both groups performed the d2-test after a regular school lesson (pre-test), after 10 min of coordinative exercise and of a normal sport lesson (NSL, control group), respectively (post-test). Exercise was controlled for heart rate (HR). CE and NSL enhanced the d2-test performance from pre- to post-test significantly. ANOVA revealed a significant group (CE, NSL) by performance interaction in the d2-test indicating a higher improvement of CE as compared to NSL. HR was not significantly different between the groups. CE was more effective in completing the concentration and attention task. With the HR being the same in both groups we assume that the coordinative character of the exercise might be responsible for the significant differences. CE might lead to a pre-activation of parts of the brain which are also responsible for mediating functions like attention. Thus, our results support the request for more acute CE in schools, even in elite performance schools.

Abstract Objectives. We examined the association between time spent in physical education and academic achievement in a longitudinal study of students in kindergarten through fifth grade. Methods. We used data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999, which employed a multistage probability design to select a nationally representative sample of students in kindergarten (analytic sample = 5316). Time spent in physical education (minutes per week) was collected from classroom teachers, and academic achievement (mathematics and reading) was scored on an item response theory scale. Results. A small but significant benefit for academic achievement in mathematics and reading was observed for girls enrolled in higher amounts (70?300 minutes per week) of physical education (referent: 0?35 minutes per week). Higher amounts of physical education were not positively or negatively associated with academic achievement among boys. Conclusions. Among girls, higher amounts of physical education may be associated with an academic benefit. Physical education did not appear to negatively affect academic achievement in elementary school students. Concerns about adverse effects on achievement may not be legitimate reasons to limit physical education programs.

Physical education, school physical activity, school sports and academic performance

Type Journal Article
Author Fran?ois Trudeau
Author Roy J Shephard
Abstract Background The purpose of this paper is to review relationships of academic performance and some of its determinants to participation in school-based physical activities, including physical education (PE), free school physical activity (PA) and school sports. Methods Linkages between academic achievement and involvement in PE, school PA and sport programmes have been examined, based on a systematic review of currently available literature, including a comprehensive search of MEDLINE (1966 to 2007), PSYCHINFO (1974 to 2007), SCHOLAR.GOOGLE.COM, and ERIC databases. Results Quasi-experimental data indicate that allocating up to an additional hour per day of curricular time to PA programmes does not affect the academic performance of primary school students negatively, even though the time allocated to other subjects usually shows a corresponding reduction. An additional curricular emphasis on PE may result in small absolute gains in grade point average (GPA), and such findings strongly suggest a relative increase in performance per unit of academic teaching time. Further, the overwhelmingly majority of such programmes have demonstrated an improvement in some measures of physical fitness (PF). Cross-sectional observations show a positive association between academic performance and PA, but PF does not seem to show such an association. PA has positive influences on concentration, memory and classroom behaviour. Data from quasi-experimental studies find support in mechanistic experiments on cognitive function, pointing to a positive relationship between PA and intellectual performance. Conclusion Given competent providers, PA can be added to the school curriculum by taking time from other subjects without risk of hindering student academic achievement. On the other hand, adding time to "academic" or "curricular" subjects by taking time from physical education programmes does not enhance grades in these subjects and may be detrimental to health.

Exercise and Children?s Intelligence, Cognition, and Academic Achievement

Type Journal Article
Author Phillip D. Tomporowski

Author Jack A. Naglieri
Abstract Studies that examine the effects of exercise on children?s intelligence, cognition, or academic achievement were reviewed and results were discussed in light of (a) contemporary cognitive theory development directed toward exercise, (b) recent research demonstrating the salutary effects of exercise on adults? cognitive functioning, and (c) studies conducted with animals that have linked physical activity to changes in neurological development and behavior. Similar to adults, exercise facilitates children?s executive function (i.e., processes required to select, organize, and properly initiate goal-directed actions). Exercise may prove to be a simple, yet important, method of enhancing those aspects of children?s mental functioning central to cognitive development.

Abstract PURPOSE The purpose of this study was twofold: 1) to evaluate the effectiveness of a school-based physical activity intervention, Action Schools! BC (AS! BC), for maintaining academic performance in a multiethnic group of elementary children, and 2) to determine whether boys and girls' academic performance changed similarly after participation in AS! BC. METHODS This was a 16-month cluster randomized controlled trial. Ten schools were randomized to intervention (INT) or usual practice (UP). One INT school administered the wrong final test, and one UP school graded their own test, so both were excluded. Thus, eight schools (six INT, two UP) were included in the final analysis. Children (143 boys, 144 girls) in grades 4 and 5 were recruited for the study. We used the Canadian Achievement Test (CAT-3) to evaluate academic performance (TotScore). Weekly teacher activity logs determined amounts of physical activity delivered by teachers to students. Physical activity was determined with the Physical Activity Questionnaire for Children (PAQ-C). Independent t-tests compared descriptive variables between groups and between boys and girls. We used a mixed linear model to evaluate differences in TotScore at follow-up between groups and between girls and boys. RESULTS Physical activity delivered by teachers to children in INT schools was increased by 47 min x wk(-1) (139 +/- 62 vs 92 +/- 45, P < 0.001). Participants attending UP schools had significantly higher baseline TotScores than those attending INT schools. Despite this, there was no significant difference in TotScore between groups at follow-up and between boys and girls at baseline and follow-up. CONCLUSION The AS! BC model is an attractive and feasible intervention to increase physical activity for students while maintaining levels of academic performance.

Physical Fitness and Academic Achievement in Third- and Fifth-Grade Students

Type Journal Article
Author Darla Castelli
Abstract The relationship between physical fitness and academic achievement has received much attention owing to the increasing prevalence of children who are overweight and unfit, as well as the inescapable pressure on schools to produce students who meet academic standards. This study examined 259 public school students in third and fifth grades and found that field tests of physical fitness were positively related to academic achievement. Specifically, aerobic capacity was positively associated with achievement, whereas BMI was inversely related. Associations were demonstrated in total academic achievement, mathematics achievement, and reading achievement, thus suggesting that aspects of physical fitness may be globally related to academic performance in preadolescents. The findings are discussed with regards to maximizing school performance and the implications for educational policies.

Author Christian Pfeifer
Abstract We analyze the impact of exercising sports during childhood and adolescence on educational attainment. The theoretical framework is based on models of allocation of time and educational productivity. Using the rich information from the German Socio-Economic Panel (GSOEP), we apply generalized ordered probit models to estimate the effect of participation in sport activities on secondary school degrees and professional degrees. Even after controlling for important variables and selection into sport, we find strong evidence that the effect of sport on educational attainment is statistically significant and positive.

The Relationship Between Physical Fitness and Academic Achievement

Type Web Page
Author James Grissom
Abstract The purpose of this study was to evaluate the relationship between physical fitness and academic achievement. To do so, scores on the FITNESSGRAM?, a physical fitness test, were compared to reading and mathematics scores on the Stanford Achievement Test 9th edition, a standardized norm-referenced achievement test. Subjects were all 5th, 7th, and 9th grade California school children enrolled in public school in 2002 for whom there was complete data on both the physical fitness and academic achievement tests. The sample size was 884,715 students. Results indicate a consistent positive relationship between overall fitness and academic achievement. That is, as overall fitness scores improved, mean achievement scores also improved. This relationship between fitness and achievement appeared to be stronger for females than males and stronger for higher socio-economic status (SES) than lower SES students. Results should be interpreted with caution. It cannot be inferred from these data that physical fitness causes academic achievement to improve. It is more likely that physical and mental processes influence each other in ways that are still being understood.

Physical activity and student performance at school.

Type Journal Article
Author Howard Taras
Abstract To review the state of research on the association between physical activity among school-aged children and academic outcomes, the author reviewed published studies on this topic. A table includes brief descriptions of each study?s research methodology and outcomes. A review of the research demonstrates that there may be some short-term improvements of physical activity (such as on concentration) but that long-term improvement of academic achievement as a result of more vigorous physical activity is not well substantiated.
