Effects Of A Single Session Of Aerobic Exercise Of Different Intensities On Inhibitory Control In The Elderly

Inhibition control is a superior response that can inhibit one's own cognition when completing a cognitive task,and the ability to control the entry of irrelevant interference information.It is a basic cognitive mechanism and a core component of executive function.Older people may show cognitive theory of mind impairment when they complete the need to suppress dominant behavioral responses.This theory of psychological impairment can be explained by the scores of the elderly when they complete the Stroop task.Single bout of aerobic exercise has been shown to positively affect individual inhibitory control,with most studies using 20 minutes of moderate-intensity aerobic exercise as an intervention,but some research have claimed a positive effect of a single 10-minute session of moderate-intensity aerobic exercise on inhibitory control in older adults,but it is unclear whether there is an effect of low-intensity single-session aerobic exercise on inhibitory control in older adults.Based on this,this research was conducted to explore the effect of 20-minute single session of low-intensity,moderate-intensity aerobic exercise on inhibitory control in older adults,and to try to describe the neuroimaging mechanism of the inhibitory control process.This research aims to enrich the exercise prescriptions of elderly exercises and provide empirical research and reference basis for the formulation of single low-intensity aerobic exercise prescriptions.This research used a 2 × 3 within-subjects design to test inhibitory control using the Stroop task and monitored the relative changes in cerebral blood flow at baseline and 20 minutes of low-and moderate-intensity aerobic exercise on completion of the Stroop task in 12 older adults by functional brain imaging with near-infrared spectroscopy(f NIRS).Results revealed significantly faster than baseline levels at response time to the Stroop congruent and incongruent tasks after low-and moderate-intensity aerobic exercise,and significantly increased oxyhemoglobin concentrations in the bilateral frontal polar regions(FPA)and bilateral dorsolateral prefrontal lobes(DLPFC)of the brain during the Stroop incongruent task.This research found that a single 20-minute session of low-and moderate-intensity aerobic exercise increased blood oxygen concentrations in the bilateral lateral frontal polar areas(FPA)and bilateral dorsolateral prefrontal lobes(DLPFC)in older adults and thus improved inhibitory control behavior performance,revealing the cognitive benefits of a single session of low-intensity aerobic exercise and providing experimental support for widespread participation in sports and exercise in older adults.
