The aim of the study was to examine the influence of acute bouts of low and moderate resistance exercise on the executive function of community-living older adults. A total of 40 older adults (20 men and 20 women; age range: 60â€"75 years) were randomly assigned to an exercise or control group. The exercise group completed two 45-min resistance exercise bouts at 40% and 70% of their individual 10-repetition maximum on different days, whereas the control group watched an exercise-related video. To assess immediate and delayed effects of exercise on executive function, tests assessing working memory, response inhibition, and cognitive flexibility were performed before (pretest), 15 min and 180 min after the exercise. Exercise improved executive function, but no change was observed in the control group. The exercise-induced gains were (a) larger after moderate- than low-intensity exercise, (b) similar for women and men, and (c) larger at 15 min than 180 min after exercise. These results indicate that exercise improves, at least transiently, executive function in healthy older adults. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
