Effects of long-term physical exercise on young people's balance ability under different cognitive tasks
Objective:To explore the balance performance of young adults under the interference of different cognitive tasks,and the moderating effect of long-term physical exercise.Method:The static and dynamic balance of healthy young people with physical exercise habit and without physical exercise habit were tested under the interference of different cognitive tasks.One-way repeated mea-sures ANOVA was performed with the group variable(Group)as the between-subjects factor and the results of multiple balance tests(Task)as the within-subjects variable.Result:Long term physical exercise had a positive moderating effect on the static balance during calculation,singing,and writing interference,the static mediolateral symmetrical balance during writing interference,the static anteroposterior symmetrical balance during singing interference,and the dynamic balance during comput-ing interference(P＜0.05).The dual-task cost of young people was significantly reduced when they are dis-turbed by the corresponding cognitive tasks(P＜0.05).However,it had a negative regulatory effect on the stat-ic mediolateral balance of calculation interference,the static anteroposterior balance of reading interference,and the dynamic mediolateral balance of calculation and singing interference(P＜0.05).Conclusion:Long term physical exercise has a significant moderating effect on young people's dynamic and static balance performance when different cognitive tasks are disturbed.
