Physical Activity, Vitamin E, and Antioxidant Capacity Associated With Improved Academic Performance
Previous research has suggested that physical activity can have an impact on cognitive skills and academic performance. A new study has found that physical activity, vitamin E levels, and total antioxidant capacity all have a positive correlation with academic performance.
One hundred and twenty students in grades 7 to 9 participated in the study. The researchers assessed maximum oxygen uptake (VO2max) at baseline. Physical activity was assessed based on the amount of time spent performing moderate and intense exercise programs. Participants were classified into three groups, mild, moderate, or active. Blood samples were taken to evaluate vitamin E levels and total antioxidant capacity. School grades ranging from 1.0 for very poor to 10.0 for outstanding were obtained at the end of the academic year.
The researchers found that participants in the moderate to intense physical activity groups had higher levels of vitamin E and higher total antioxidant capacity. Academic performance and executive function were found to be higher in the moderate to intense physical activity groups, compared to the mild group.
The study was conducted by researchers from King Saud University. It was published online ahead of print on May 17, 2019 in BMC Pediatrics.
