Effects of Moderate Exercise on Cortical Resilience: A Transcranial Magnetic Stimulation Study Targeting the Dorsolateral Prefrontal Cortex.

摘要: OBJECTIVE The beneficial effects of exercise on the brain regions that support cognitive control and memory are well documented. However, examination capacity acute to promote cortical resilience-the ability recover from temporary pertubation-has been largely unexplored. present study sought determine whether single session moderate-intensity aerobic can accelerate recovery inhibitory centers in dorsolateral prefrontal cortex after transient perturbation via continuous theta burst stimulation (cTBS). METHODS In a within-participants experimental design, 28 female participants aged 18 26 years (mean [standard deviation] = 20.32 [1.79] years) completed each very light-intensity exercise, randomized order. Before session, received active cTBS left cortex. A Stroop task was used quantify both initial subsequent control. RESULTS Results revealed significant condition (moderate-intensity exercise) by time (prestimulation, poststimulation, postexercise) interaction (F(2,52) 5.93, p .005, d 0.38). Specifically, proportion cTBS-induced decrement inhibition restored at 40 minutes postexercise significantly higher bout (101.26%) compared with (18.36%; t(27) -2.17, .039, -.57, 95% confidence interval -161.40 -4.40). CONCLUSION These findings hypothesis promotes resilience, specifically relation resilience-promoting have empirical theoretical implications for how we conceptualize neuroprotective exercise.
