An Experimental Study On The Participation Of Physical Homework In Promoting Physical And Mental Health Of Overweight And Obese Primary School Students

With the development of the society,the rate of overweight and obesity is increasing rapidly.Obesity is a chronic disease that affects students’ physical and mental health,intellectual development and social resilience.the prevention and intervention of obesity has always been a problem of many concerns,but most of the interventions are mainly short-term.the purpose of this study is to explore the effect of long-term physical and mental homework intervention on the physical and mental health of obese students,and to provide relevant theoretical and practical basis for long-term intervention measures to control overweight and obesity of adolescent students.Eighty-six overweight and obese students aged 10 years in Jinhui Primary School and Jincheng Primary School of Chengdu High-tech Zone were selected as experimental subjects.There are 45 students in the experimental class(21 boys and 24 girls)and 41 students in the control class(20 boys and 21 girls).The experimental group was assigned sports homework with no less than 30 minutes of effective practice time 3 ～ 4 times a week.After 40 weeks of implementation,the students’ body shape height,weight,BMI index,vital capacity in body function,50 m running,1min skipping,sitting forward bend and 1min sit-up in physical fitness,body self-esteem and physical exercise behavior were investigated.Independent sample t test and paired sample t test were used to analyze the data results.The results are as follows:(1)the weight and BMI of overweight and obese students decreased after participating in sports homework.(2)participation in sports homework increased the lung capacity of overweight and obese students.(3)After participating in sports homework,the four physical fitness indexes of overweight and obese students,such as 50-meter running and 1min rope skipping,were significantly improved.(4)participation in sports homework effectively improved the frequency,time and intensity of physical exercise for overweight and obese students.(5)participation in sports homework improved the level of body self-esteem of overweight and obese students.In conclusion,the physical quality,shape,function,body self-esteem and physical exercise behavior of overweight and obese students have been significantly improved after participation in sports homework.
