Dose Characteristics of School Physical Exercise in Alleviating Negative Emotions:Dimensions of Exercise Frequency and Exercise Duration
摘要
Abstract
In order to clarify the characteristics of exercise dose for adolescents to alleviate negative emotions in the context of school sports,and to explore the regularity of solving psychological behavior problems of adolescents from the perspective of school physical exercise,this study utilizes the trace data from the China Education Panel Survey(CEPS)from 2014 to 2015 to conduct empirical analysis on a sample of 8 984 middle school students through multiple regression,U-test and nonlinear regulatory effect analysis.The results indicate that the relationship between weekly exercise frequency and negative emotions does not exhibit a U-shaped pattern,but a consistent declining trend,which means the higher weekly exercise frequency yields better outcomes;exercise duration has a U-shaped relationship with negative emotions,which means negative emotions initially decrease and then increase with longer exercise duration which optimal interval is 40-60 minutes;learning stress can weaken and relieve the U-shaped relationship between exercise duration and negative emotions.In comprehensive effect,3 times a week and 50-60 minutes each time,or 6 times a week and 50-120 minutes each time,can get good results of improving negative emotions.To promote the psychological health of adolescents,school physical exercise should ensure the students'exercise duration of about 1 hour per day and guide the reasonable allocation of study and exercise time to prevent the risk of excessive exercise leading to increased negative emotions under high learning stress.关键词
