An Experimental Study On The Influence Of Exercise App Intervention On College Students’ Physical Fitness:The Chain Mediating Role Of Exercise Motivation And Exercise Persistence

Since the reform and opening up,the market economy has been developing rapidly and the living standard of residents has been climbing.With the expansion of university enrollment,the number of college students is increasing,and the attention of all sectors of society to college students is also increasing.In recent years,college students’ physical health has become a hot issue,which is not only related to the future of the country and the nation,but also related to the happiness of hundreds of millions of families.Since the Ministry of Education promulgated the National Students’ Physical Health Standards in2014 and implemented them,the physical health standards of domestic students have been on the rise.However,the results of the eighth national survey on students’ physique and health show that the rate of college students’ physique reaching the standard of good and good has hardly increased.Therefore,by comparing the physical fitness changes of college students before and after using sports apps,this study aims to understand whether sports apps have a positive impact on college students’ physical fitness after exercise,and whether there is a chain mediating effect between the use of sports apps,physical fitness,exercise motivation and exercise persistence.Through exploring various relationships between them,the thesis puts forward more effective ways to use sports apps,so as to improve the physical quality of college students.Methods: Taking 200 undergraduates of Hangzhou Normal University as survey objects,including 100 male students and 100 female students,50 male students and 50 female students were respectively taken as a group,the experimental group and the control group were set up,and there was no significant difference in the data between the two groups before the experiment.The results of physical health test,exercise motivation and physical exercise persistence of college students were collected.Descriptive analysis and multiple linear regression analysis were used for statistical processing of the data,and the mediating role of the data was analyzed.Research results:(1)Based on the requirements of National Students’ Physical Health Standards,the exercise APP intervention experiment was carried out.Through the experimental research,it was found that the test scores of college students were significantly improved after the use of exercise APP,which can be judged that the exercise APP intervention can effectively improve the institutional health level of universities;(2)There was a significant positive correlation among APP intervention,physical fitness,exercise motivation and exercise persistence;(3)Exercise motivation and exercise persistence play a partial mediating role in the relationship between exercise APP intervention and physical health,with the mediating effect accounting for 60.85% of the total effect.Conclusion: Through the experimental study found that sports APP intervention has a significant impact on the physical fitness of college students,help to improve the physical fitness of college students.There is a chain mediating effect between the influence of sports apps on college students’ physical fitness,their exercise motivation and exercise persistence.The use of sports apps can directly improve the physical health of college students,but also indirectly improve the physical health level of college students by affecting their exercise motivation and exercise persistence and its chain mediation.
