Abstract
Evidence suggests that acute exercise is an effective way for improving inhibition control, however, the effect of different types of Acute Aerobic Exercise and Inhibitory Control (IC) remains unclear. Using a crossover design, 25 participants (M = 20.20year, SD=0.91) completed 20 min of interventions at 1) moderate intensity exercise, 2) moderate intensity exercise with high cognitive demand (high cognitive-demand exercise), 3) moderate intensity exercise with high physical demand (high physical-demand exercise), and 4) rest condition (low physical and cognitive demand) in a counterbalanced way. Flanker task was completed before and after each intervention to evaluate their inhibitory control ability. The four interventions significantly reduce reaction times for both congruent and incongruent trials with Flanker task (all P < 0.05). Compared to acute moderate intensity exercise, high physical-demand exercise induced a greater reduction in reaction times for both trial types, whereas high cognitive-demand exercise led to faster reaction times in incongruent trials. Although each intervention effectively enhanced inhibitory control, the exercise demanding high cognitive and physical effort contributed to a more pronounced improvement in inhibitory control performance. This indicates that both increased physical and cognitive engagement can significantly improve the level of inhibitory control in young adults.
