| Inhibitory control is defined as the ability of an individual to repeal a dominant response,or to suppress a reaction deemed to be irrelevant,inappropriate,and no longer required.Inhibitory control is an important component of executive function,and plays an important role in human cognitive activities such as intelligence,learning and reasoning.It is found that acute aerobic exercise may affect the inhibitory control function of an individual.However,acute aerobic exercise has a complex relationship with changes of the inhibitory control function,and it is affected by many factors,known as the existence of the so-called “dose effect”.It refers to the relationship between the various elements of individual aerobic exercise and the interaction and cognitive function,such as exercise intensity,measurement of cognitive tasks,cardiopulmonary function,and exercise.However,most researches only take a variety of factors as independent variables,while the other factors are taken as control variables.A few of researches focus on the interaction between various factors which affect the function of inhibitory control training.It is found in the researches that duration of cardiopulmonary function and the measurement of the cognitive task will affect the inhibition function,and no research focuses on interaction of these two factors.Hence,this research intends to take high and low cardiorespiratory functions of college students as the research object,so as to explore the short-term dynamic changes of moderate intensity aerobic exercise at different stages of the individual inhibition control function.In the first research,female college students of 18-21 years old were selected as the research object.The subjects were divided into two groups: high and low cardiorespiratory functions,wherein the Stroop task was used to measure the inhibitory control function.It was shown in the results that: in the Stroop task,results obtained in the consistent trial,the inconsistent trial,and the neutral trial were significantly lower than those of the low cardiorespiratory function group.With regard to the interference effect,the interference score of the high cardiorespiratory function group was significantly lower than that of the low cardiorespiratory function group.In the second research,female college students of 18-21 years old were taken as the research object.With application of the Bruce method,the subjects were divided into two groups of high and low cardiorespiratory functions.In-group crossover design was used to conduct 30 minutes of moderate intensity acute aerobic exercise to the two groups of subjects.Before and after the exercise,Stroop was used to measure task inhibitory control function of the subjects.The results showed that: in comparison with the control group,after acute moderate intensity aerobic exercise,high and low cardiorespiratory functions of the two groups of subjects in the consistent trial,the inconsistent trial,and the neutral trial were significantly lower than the control group.After short-term exercise,the inhibition scores of the two groups were significantly improved.In the third study,female college students of 18-21 years old were taken as the research object.With application of the Bruce method,the subjects were divided into two groups of high and low cardiorespiratory functions.In-group crossover design was used to conduct 30 minutes of acute moderate intensity aerobic exercise to the subjects.During exercise,immediately after exercise,and after post-exercise delay of 30 minutes,the Stroop task was used to measure the inhibitory control function of subjects.The results showed that: during the exercise and immediately after the exercise,the task response of high cardiorespiratory function of subjects and control groups manifested no significant difference,while the low cardiorespiratory function task response group was significantly greater than that of the control group;after post-exercise delay of 30 minutes,the task response of two subject groups of high and low cardiorespiratory functions were significantly lower than that of the control group.However,no significant difference existed in the scores of interference between the groups during the exercise,immediately after exercise and after post-exercise delay of 30 minutes.Based on above results,this research concluded that: 1)inhibitory control ability of the high cardiorespiratory function group was significantly better than that of low cardiorespiratory function group;2)through acute aerobic exercise,inhibitory control abilities of cardiorespiratory function level of the two groups of subjects were significantly improved,but the improvement effect of low cardiorespiratory function group prevailed over that of the high cardiorespiratory function group;3)the high cardiorespiratory function group was not influenced by the movement interference during the exercise and immediately after the exercise in a short period of time,and the low cardiorespiratory function group was influenced by the movement of interference during the exercise and immediately after the exercise in the short term,the general information processing ability of the cardiorespiratory function of two groups of subjects was significantly improved after post-exercise delay of 30 minutes,but the senior inhibitory processing abilities of the two groups of subjects were not significantly improved at three movement stages. |
