Health A Majority of The World’s Teens Aren't Getting Enough Physical Activity People who reported doing more physical activity showed higher scores on cognitive testsconsistent with previous studies linking more exercise to better brain health. But when the researchers adjusted for the effect that factors like high blood pressure, diabetes and heart disease can have on brain function, the link disappeared. Conditions like these could impair blood flow to the brain and therefore compromise cognitive functions, says Dr. Clinton Wright, associate professor of neurology and public health sciences at University of Miami and senior author of the study. That suggests that people with low physical activity levels also had a greater burden of those risk factors, he says. Get our Health Newsletter.

at the beginning and end of the study. They found similar trends showing that people who exercise more had higher cognitive scores, while those who were less physically active tended to have lower scores. This time, even after accounting for the contribution of possible confounding factors, they found that this trend remained strong in two areas in particular: thinking speed and memory of specific past events.

The drops were equivalent to the declines found during normal aging over about 10 years, they concluded. MORE: Exercise Makes Kids Brains More Efficient The data doesnt prove that exercise can actually reverse or prevent a slowdown in higher level thinking skills. But it does suggest that physical activity may help people with bloo
d flow issues to the brain, such as stroke patients, maintain their cognitive status. Wright is already studying such a group of patients who will wear activity moni
tors and be randomly assigned to a physical exercise program or not to see whether there is any difference in their test scores over time. Contact us at email@example.com.
