Exercise and Academic Performance: Implications of Aerobic Capacity and Hand Grip Strength in Middle-School Students
Exercise and Academic Performance: Implications of Aerobic Capacity and Hand Grip Strength in Middle-School Students

Summary/Abstract: The regular practice of physical exercise has a positive role on mental health and a positive contribution to the development of cognitive function, considered beneficial to academic performance. The present study aimed to analyse the impact of physical exercise on students' academic performance. 227 students participated, of which 112 (49.3%) were male and 115 (50.6%) were female, aged between 10 and 13 years old, from 5th and 6th grades in a Portuguese public school. The Susan Harter Self-Concept Scale validated for the Portuguese population was used, and a descriptive and inferential analysis of the data was conducted to analyse the levels of handgrip strength, aerobic capacity and academic performance. Linear regression analysis was used to interpret the predictive variables and we calculated the magnitude of the effect. The results suggest that the practice of physical exercise enhances the levels of aerobic capacity, handgrip strength and academic performance of students. In addition to physical education classes, the individual sports combined with the team sports present very positive values in relation to the variables described.
