The Influence Of Physical Exercise On Dolescent Aggression:Mediating Effect Of Executive Function

Objective: to seek effective measures to prevent or alleviate juvenile aggressive behavior;To explore whether physical exercise can reduce aggression;As an intermediary,the executive function has the relationship between the function and the reducing of aggression,physical exercise and execution function;This paper aims to construct a harmonious and safe campus and promote the development of the young people through the horizontal and vertical research.Methods: This paper studies 117 teenagers(14-16 years old)by horizontal research method through two experimental studies.The relationship among physical exercise,explicit attack and executive function is explored.In the second study,112teenagers(14-16 years old)were studied by longitudinal research method.The exercise intervention group and control group were set up.The data of pre and post-test were analyzed,and the intervention,aggression and executive function of long-term physical training were studied.Physical exercise and explicit attack were collected by questionnaire,and E-Prime was used to collect data for execution function and implicit attack.Spss23.0 was used to analyze the data.Results: the results were as follows:(1)the amount of exercise was small the amount of exercise was higher than that of the middle one in different intensity(2)There was a correlation between physical exercise and explicit attack,and the inhibition and control function in executive function was significantly related to physical exercise(r =-0.21,P < 0.05)and explicit attack(r = 0.28,P < 0.05).There is a correlation between physical exercise and implicit attack.Attention conversion function in executive function is significantly related to physical exercise(r =-0.12,P < 0.05)and implicit attack(r = 0.20,P < 0.05)(3)The inhibition of control function(C ’=-0.13)plays a complete mediating role in physical exercise and explicit attack;Attention switching function(C ’=0.00)plays a complete mediating role in physical exercise and implicit attack.The results showed that:(1)in the exercise intervention group and the control group,the difference of the external attack(F = 15.22,P < 0.05)was significant,the difference of implicit attack(F = 0.22,P > 0.05)was not significant,the information refresh function(F = 4.73,P < 0.05)was significant,the inhibition control function(F = 16.20,P < 0.05)was significantly different,and the attention conversion function(F = 0.50),The difference was not significant(2)The difference of the explicit attack(F = 34.44,P < 0.05)was significant in the pre-test and post-test time,the difference of implicit attack(F = 1.60,P < 0.05)was significant,the information refresh function(F = 23.27,P < 0.05)was significantly different,the inhibition control function(F = 20.50,P < 0.05)was significantly different,and the attention conversion function(F = 51.85,P < 0.05)was significantly different.Conclusion:(1)the overall exercise amount is low in terms of physical exercise quantity.In different sports,the subjects with medium exercise amount have the highest function of information refresh,inhibition control and attention conversion,the second is the large amount of exercise and the lowest in small exercise;In terms of external attack,the subjects were in the middle level,and the average exercise volume was the lowest in different exercise;In terms of implicit attack,the lowest implicit attack was found in the subjects with moderate exercise(2)Physical exercise can prevent and reduce the adolescent explicit attack.The effect of physical exercise on the explicit attack of teenagers can be realized by inhibiting the control function,and the control function plays a complete intermediary role(3)Physical exercise can prevent and reduce the implicit attack of teenagers.The effect of physical exercise on the implicit attack of adolescents is realized by the function of attention conversion,and the function of attention conversion plays a complete intermediary role(4)In the horizontal and vertical research,the exercise with medium exercise can improve the executive function of teenagers and reduce the explicit and implicit attack behaviors of teenagers.
