To investigate the dose-response effect of green elements and duration of green exercise on executive function among college students.
Using a mixed experimental design, 90 physically active college students were assigned to greener and less green environment exercise groups and 10-, 20-, and 30-minute exercise durations according to their physical activity level. All subjects completed a moderate-intensity two-legged jump-rope workout, during which heart rate was monitored using a Polar RS800. Inhibitory control, working memory and cognitive flexibility were tested before and after the exercise.
(1) The inhibitory control as well as working memory in the greener group was significantly better than that of less-green environment at the end of the exercise; (2) inhibitory control, working memory, and cognitive flexibility were significantly better in 20 versus 30 minutes condition than in 10 minutes, but 20 versus 30 minutes was not significant.
Green environments and long duration exercise are more conducive to improving executive function, but there is no significant synergistic effect of green environments and exercise duration.
