Does Exercise Help With Studying?

As a Dutch review of previous studies suggests, being physically active can have a positive effect on the child’s academic performance. The review examined 14 studies which include more than 12,000 children. According to those studies, engaging in physical exercise may help increase blood and oxygen flow to the brain, boosting the cognitive function of the children.

Writing in Archives of Pediatrics & Adolescent Medicine, researchers stated that they discovered strong evidence of a relation between physical activity and academic performance.

However, according to VU University Medical Center in Amsterdam, the authors of the said research, they stated that more accurate and reliable measurement instruments were required to examine the link in greater detail.

Dr. Amika Singh and colleagues were triggered to observe the connection between exercise and the child’s performance in the classroom due to concerns that the pressure to improve the grades and performance of the students could result into more time being spent in the classroom and very limited time to perform physical exercise.

So the authors identified ten observational and four interventional studies for review. Twelve of the mentioned studies were done in the U.S., one in Canada and one in South Africa. The sample sizes of the studies varied between fifty-three to twelve thousand subjects between the ages of six to eighteen years old, the period of follow-up ranges from eight weeks to more than five years.

As the study suggests, two of the reviewed researches were evaluated as being of high quality.

Blood flow

According to the researchers, they noticed a clear proof of a “significant positive relationship” between exercise and academic performance using those two studies as evidences.

The study suggests that the reason behind it is that exercise is responsible for increasing the blood and oxygen flow to the brain. The improvement in the blood and oxygen flow positively affects the cognitive functions of the brain. However, according to the researchers, more studies were needed to investigate the exact connection between physical activity and academic performance.

Participating in any kind of physical activity also helps in stress management, mood regulation, and it can also alleviate anxiety, helping children behave better in the classroom.

According to Dr Singh, “children who learn to participate in sport also learn to obey rules. This may mean they are more disciplined and able to concentrate better during lessons.”

“People always ask, ‘How much exercise do I need to do to get an A?’ We don’t know that, but we would like to find out,” said Dr. Singh. “Children should be active for at least one hour a day, for health reasons. But we also need to look at other things, like what kind of activities they should do, when they should do them and for how long.”

None of the studies used an objective measure of physical activity. Most of the studies instructed the subjects or their parents to write down how much physical activity they were getting.
