Physical Activity,Inhibitory Function And Internet Addiction Among Middle School Students:Relationship And Role

Research background:With the continuous development of the Internet scale,more than one billion users in China have access to the Internet,and the proportion of young people in all Internet users is as high as 26%.The problem of teenagers’ Internet addiction is becoming more and more serious in China.The proportion of teenagers’ Internet addiction is between 6% and 14%.More reports show that teenagers in some areas of China have the highest detection rate of Internet addiction.Internet addiction not only has a negative impact on the body and mind of teenagers,but also does great harm to the family and society.Research shows that compared with normal people,the inhibitory function of Internet addicts is impaired.A large number of literatures have proved that the higher the physical activity,the better the inhibitory function.It is worth noting that the relationship among physical activity,inhibition function and Internet addiction is not clear.Therefore,this study aims to explore the relationship between physical activity,inhibitory function and Internet addiction in middle school students through a cross-sectional survey Purpose of the study:(1)By investigating the physical activity,inhibition function and Internet Addiction of middle school students,this paper analyzes the differences of physical activity,inhibition function and Internet addiction among middle school students of different genders and grades(2)By analyzing the relationship among physical activity,inhibitory function and Internet addiction in middle school students,this paper discusses the regulatory effect of inhibitory function between physical activity and Internet addiction in middle school students.Research methods:This study adopts the method of literature,based on the relevant literature of databases at home and abroad,to provide a theoretical basis for this study.Taking middle school students in Shanghai Shidong experimental school as the survey object,through the school computer room and taking the class as the unit,this paper conducted an online questionnaire survey on physical activity and Internet addiction.Use e-prime3 0 software test was used to test the inhibitory function of 216 middle school students.Spss18 0 software to process and analyze the questionnaire and behavior data,calculate the frequency and mean value through descriptive statistics,calculate the significant difference between samples through multiple analysis of variance,and calculate the correlation and significance of each variable through correlation analysis,through process3 3.The adjustment effect was calculated by software,and the significance level was taken as 0.05.Research results:(1)A total of 216 subjects were included in the analysis,including 114 males,accounting for 52.77%,and 102 females,accounting for 47.22%.The number of low,medium and high physical activity was 103,66 and 47 respectively,accounting for47.68%,30.55% and 21.75% respectively.There were 44 middle school students with internet addiction,accounting for 20.37%.Demographically,there is no significant difference in physical activity,inhibition function and Internet addiction between middle school students and different gender and grade.(2)Middle school students have significant correlation with internet addiction and physical activity inhibition.There was a significant negative correlation between physical activity and go response time in inhibitory function(r =-0.202,P < 0.01);There was a significant negative correlation between physical activity and Internet addiction score(r = 0.446,P < 0.01);There was a significant positive correlation between Internet addiction score and go response time in inhibitory function(r =0.223,P < 0.01);There was a significant positive correlation with the reaction time under inconsistent conditions(r = 0.136,P < 0.05).(3)the inhibitory effect of middle school students on physical activity has a moderating effect on the influence of Internet addiction,and the moderating effect is2.4%,reaching a significant level(P=0.0108).Research conclusion:(1)The physical activity of middle school students is not optimistic,and the problem of Internet addiction is more prominent.Demographically,there is no significant difference in physical activity,inhibition function and Internet addiction degree between middle school students and different gender and grade,suggesting that different gender and grade have no effect on middle school students’ physical activity,inhibition function and Internet addiction degree.(2)There is a very significant relationship between physical activity and inhibitory function of middle school students.Through analysis,it is found that there is a positive correlation between them.At the same time,physical activity is also closely related to the degree of Internet Addiction of middle school students,and there is a negative correlation between them.The degree of Internet Addiction of students is also positively correlated with inhibitory function.It can be concluded that if the physical activity of middle school students is high,it can be judged that the better their inhibitory function is,the lower their degree of Internet addiction will be;The higher the degree of middle school students’ Internet addiction,the worse their inhibitory function.(3)Inhibition function has a regulatory effect between physical activity and the degree of Internet addiction in middle school students,that is,compared with internet addicts with lower inhibition function,the group with higher inhibition function shows a lower degree of Internet addiction,and the effect of physical activity on the degree of Internet addiction is relatively low.It is suggested that the effect of physical activity on Internet addiction in middle school students is affected by inhibitory function.
