Effects Of Different Exercise Types On Inhibition And Control In College Students

Inhibitory control refers to the process of individual suppression of cognitive process or cognitive content,which is the core component of executive function,and its performance is mainly in cognition and behavior.At present,Stroop experimental paradigm is the first choice in the research field of cognitive inhibition,while Go/Nogo paradigm is mainly used in the research field of behavioral inhibition.Due to the continuous progress of The Times and the continuous improvement of the level of science and technology,the requirements for the refinement of experimental results are also increasing.fNIRS technology mainly reflects the signal of the cerebral cortex by accurately detecting the changes of oxygenated hemoglobin and deoxygenated hemoglobin.The accuracy of the test is accepted by the majority of scholars,so the application of fNIRS technology is becoming more and more popular.During exercise,stimulation to the brain improves the blood flow to the brain and the supply of oxygenated hemoglobin to the brain,and ultimately improves the efficiency of neurovascular coupling in the brain.Through fNIRS technology,behavioral task experimental paradigm and brain activation can be combined to study the mechanism of inhibiting control ability.Previous studies have shown that Stroop task and Go/Nogo task can activate prefrontal cortex signals;In addition,no matter in the open exercise group or the closed exercise group,it is well proved that exercise has a certain promotion effect on inhibition and control ability.Therefore,this study intends to use fNIRS technology to explore the mechanism of physical exercise on inhibition and control ability.Research objectives:1.Taking college students as the research object,the classic Stroop paradigm was adopted to explore the differences in cognitive inhibition between different exercise modes.2.Taking college students as the research object,the classic Go/Nogo paradigm was adopted to explore the differences in behavioral inhibition among college students with different exercise styles.3.Taking college students as research objects,fNIRS technology was used to record the hemodynamic response function to describe the changes of blood flow in a specific brain region after receiving a certain stimulus,so as to explore the activation states of different brain regions in different exercise modes for college students during Stroop task and Go/Nogo task.Research Methods:1.Fourteen students in the closed exercise group and the open exercise group were selected to complete the collection accuracy and response time of Stroop task.2.Fourteen students in the closed exercise group and the open exercise group were selected to complete the Go/Nogo task,and the response time and error rate were collected.3.To explore the effects of different exercise modes on the activation patterns of the prefrontal cortex during the Stroop task and the Go/Nogo task by using behavioral measurement and near-infrared spectroscopy.Results:1.For Stroop task,the response time of Stroop effect in the open exercise group was significantly higher than that in the closed exercise group,and the difference in response time was significant(P<0.05),but there was no significant difference in accuracy between the two groups.2.In the Go/Nogo task,the response time of the enclosed exercise group was significantly higher than that of the open exercise group,and the difference in response time was significant(P<0.05),but there was no significant difference in accuracy between the two groups.3.In the Stroop paradigm fNIRS study,there were significant differences in the activation degree of different brain regions between the two groups of subjects(P<0.05).In the Go/Nogo paradigm,there were significant differences in the activation degree of different brain regions between the closed exercise group and the open exercise group.Research Conclusions:1.In the Stroop paradigm,the response time index of the enclosed exercise group was lower than that of the open exercise group,that is,the cognitive inhibition ability of the enclosed exercise group was stronger than that of the open exercise group.The effect of enclosed exercise on cognitive inhibition was more obvious.2.In the Go/Nogo paradigm,the response time of college students in the open exercise group was shorter,that is,the behavior inhibition ability of college students in the open exercise group was stronger than that in the closed exercise group.The influence of open exercise on the inhibition ability of behavior is stronger.3.VLPFC,DLPFC and OFC were the main activated regions in the behavioral inhibition task in the open exercise,while VLPFC and DLPFC were the main activated regions in the cognitive inhibition task;The main activated regions were OFC,VLPFC and FPA in the cognitive inhibition task,and VLPFC,DLPFC and OFC in the behavioral inhibition task.
