The Influence of Physical Exercise on Academic Achievements of Adolescents:Effects and Characteristics
Physical exercise has a positive impact on adolescents'academic performance.Using a sample of 150,000 el-ementary school student questionnaires from the compulsory education quality monitoring of Jiangsu Province in 2020,this study calculated the effect size of physical exercise by using pan-precise exact matching weighted regression,compared the contribu-tion rates of physical exercise with homework duration and extracurricular tutoring by using Shapley value decomposition technol-ogy,and analyzed the impact of physical exercise on academic performance of different types of students by using quantile regres-sion.The study has found that physical exercise has a"high efficiency"value in improving students'academic performance with a higher contribution rate than purely academic investment.It also has a particularly beneficial effect on"struggling students"and can mitigate the adverse impacts of family background on primary school students.Based on this,it is recommended that the policy should continue to adhere to the general direction of reducing academic burdens;school administrators should create condi-tions for students to have one hour of physical exercise outside school;parents should shift their focus from an emphasis on aca-demic study only while neglecting physical education;and teachers may consider using physical exercise as an educational inter-vention to improve student learning.
