Effect of Acute Aerobic Exercise on Executive Function（EF）of Elderly People:Evidences from fNIRS and Behavior Experiments

Objective:Brain imaging technique was used to monitor the changes of the brain activation patterns in the process of psychological task to reflect the effect of the aerobic exercise on the executive function and to evaluate the training effect of the aerobic exercise on the performance of the executive function.Methods:The behavior and brain activation patterns of 15 elderly people with 10 min moderate intensity cycling were discussed by means of behavioral measurement and near infrared spectroscopy(fNIRS).Results:The Flanker interference of reaction time(RT)of the experiment group was significant lower than the control group(t(1,14)=-2.64,P<0.05).The flanker interference of oxy-Hb single of experiment group was significant higher than the control group in left frontopolar area(L-FPA)(t(1,14)=3.94,P<0.001),Conclusions:10min moderate intensity aerobic load can significantly improve the operation behaviors of the elderly flanker task,and enhance the neural activity in the left frontal pole(L-FPA)and the improvement of local regions of the brain neural activity increased with cognitive performance synchronization occurs.
