Physical exercise may help kids study better, say researchers

ALL WORK AND NO PLAY makes Jack a dull boy, goes an old adage. It may, after all, be true, says a group of researchers at the Vrije Universiteit University Medical Centre in Amsterdam (The Netherlands). The researchers, led by Dr. Amika Singh, conducted a study to find whether there is any link between children’s physically activity and their performance in the classroom. The researchers say that although more accurate and reliable measurements were needed to examine the connection in greater detail, they did find ‘strong evidence’ of a ‘significant positive relationship’ between physical activity and academic performance. Writing in Archives of Paediatrics and Adolescent Medicine, the team said exercise may help cognition by increasing the flow of blood and oxygen to the brain. Similarly, physical activity reduces stress and improves mood, which probably makes children more likely to behave in the classroom, they said. Besides, children who played any kind of sport also learn to obey the rules (of the game), which could mean that they would be more disciplined in the classroom and be able to concentrate better on the lessons, according to Dr. Singh. “We still have to find out how much exercise would be needed to get good grades, but we do feel that for health reasons, children should be active for at least an hour every day. However, we also need to find as to what kind of, time of day and duration children should do exercises,” he said. The study was prompted by concerns that the pressure to score high marks in school was forcing children to spend more time studying, and, therefore, less time doing physical activity. The team then conducted ten observational and four interventional studies involving children between six and 18 years of age. They conducted 12 studies in the US, one in Canada and one in South Africa. The follow-up period was from eight weeks to more than five years. Archives of Paediatrics and Adolescent Medicine is a monthly peer-reviewed journal for physicians and other professionals, published by the American Medical Association. INCIDENTALLY, although the spirit of the proverb cited at the beginning of this piece has existed earlier, its modern form first appeared as long ago as in 1659 in Anglo-Welsh historian and writer James Howell’s Proverbs in English, Italian, French and Spanish and in his Paroimiographia. It was later included in several collections of proverbs. Some writers even added a second part to the proverb, like Irish writer Maria Edgeworth did in her 1825 novel Harry and Lucy Concluded: “All work and no play makes Jack a dull boy, All play and no work makes Jack a mere toy.”
