Acute Effects of Strength Training Over Executive Functions in Adolescents: A Randomized Controlled Trial

A group of 50 age-schooled adolescents was randomized into one intervention and another control group of 25 subjects each. After estimating one maximum repetition for all the participants in a previous session, the intervention group performed a resistance training based on a resistance exercise of 3 sets of 3 to 5 repetitions (90% of an estimated 1 RM) whereas the control group performed both stretching and balance exercises. Measures of executive functions ( i.e. a cognitive function associated with academic performance) were taken for all the participants before and after the training. Both independent and paired t-test will serve to check differences between and within groups respectively. The selected resistance exercise is based on a global muscle involvement.
