Effects Of Acute Open And Closed Skill Sports On Inhibitory Control

Purpose: Inhibitory control is an advanced cognitive function that plays a very important role in daily life.The effect of exercise on cognitive enhancement has been proven by numerous studies.More and more studies have explored the maximum cognitive value of sports from the perspectives of exercise intensity,exercise duration,and exercise types.The exercise types can be divided into open skill sports and closed skill sports according to the stability and unpredictability of the external environment.Do these two different exercise types affect inhibitory control differently? Are open skill sports with more cognitive involvement superior? In cross-sectional studies,cognitive advantages have been observed in open skill sports,but the results in acute exercise are equivocal.Therefore,our study explores the impact of acute open and closed skill sports on inhibitory control from the perspective of exercise types,and whether open skill sports have cognitive advantages over closed skill movements in inhibitory control.Method: Groups(badminton,running,and watching videos)are independent variables.Each person participated in three interventions in a balanced order of badminton,running,and watching videos.The exercise intensity of the exercise group was 50-60% of the heart rate reserve,and the exercise duration was 30 minutes.The control group watched a 30-minute documentary.In this study,inhibitory control is divided into disturbance inhibition and response inhibition.In Study 1,after the intervention,the Flanker task was uesd to measure interference suppression,and ERP was recorded at the same time.In Study 2,the Gonogo task was used to measure response inhibition after the Flanker task,and ERP was recorded at the same time.The correct rate,reaction time,N2 and P3 average amplitudes were selected for repeated measures analysis of variance.Results: Study 1 found that on Flanker correct rate and response time,the main effect of group was not significant,and the main effect of condition was significant.In N2 and P3 average amplitude,the main effect of gourp is not significant,and the main effect of condition is not significant.Study 2 found that on Go reaction time,the main effect of group was significant,and post-hoc comparative analysis found that badminton Go reaction time was significantly shorter than running.In correct rate,the main effect of group was not significant.In the average amplitude of N2,the group main effect is significant,and the post-hoc comparative analysis shows that the N2 amplitude of badminton is significantly greater than control.In the mean amplitude of P3,the main effect of group was not significant.Conclusion:(1)In interference suppression,compared to closed skill sports,acute open skill sports showed no cognitive advantage.(2)In response inhibition,acute open skill sports performed better than closed skill sports in speed of inhibition,and the possible neural mechanism advantage is that open skill sports are more sensitive to conflicting information detection and better prepared for stimuli.In terms of the duration of the cognition-promoting effect of exercise,the cognitive benefit of open skill sports lasts longer than that of closed skill sports.
