An Experimental Study On The Effect Of Eight-week Different Intensity Exercise Intervention On The Physical Quality Of Overweight Primary School Students

In recent years,under the concern of the Party and the state,the physical health level of primary school students has improved significantly,but overweight,obesity is still a primary school students physical health problems.Since the promulgation and implementation of the “healthy China” strategy,it has become the consensus of the sports circle to solve the problem of overweight of primary school students through scientific sports intervention.How to adopt reasonable exercise intensity and appropriate amount of exercise,and get the most effective effect to improve the body shape of overweight pupils is a theoretical and practical problem concerned by the academic community.Taking this as the logical starting point,this paper adopts the research methods of Literature,Experiment,Mathematical Statistics and experiment,and takes the overweight primary students of Dalin Primary School in Tianfu new district of Chengdu as the experimental objects,to explore the influence of different intensity exercise intervention on the body shape quality of overweight primary school students by means of 8-week exercise intervention of different exercise modes and exercise intensity,to provide theoretical and practical reference for effectively improving the body shape quality of overweight pupils.In this study,60 overweight primary school students were randomly divided into low-intensity Group,middle-intensity Group and Control Group.Each group had 20 students,and the number of boys and girls was the same,eight weeks(October 2019-december 2019)of different intensity of the exercise intervention experiment,collected the relevant data compared to carry out comparative analysis.The results are as follows:(1)moderate and low intensity exercise intervention has certain influence on the body shape of overweight pupils,which proves the effectiveness of exercise intervention in improving the body shape of overweight pupils;(2)low intensity exercise intervention can help overweight pupils to improve their body shape,but moderate intensity exercise intervention has more obvious effect,and has good effect of weight reduction and weight reduction;(4)aerobic training of moderate and low intensity,such as rope skipping,jogging and interval training,can improve the body shape,physical function and quality of overweight pupils,among them,rope skipping is more effective in promoting height growth,reducing body weight,reducing body fat rate,and improving sensitivity and coordination quality,while jogging is more effective in strengthening body function,reducing body fat rate,and improving speed and endurance quality,the effect of Interval Aerobic Training on weight reduction,physical function and endurance is more obvious.(5)through sports intervention,the female students get better weight reduction effect than the male students,boys were better than girls at improving speed,abdominal strength and flexibility.
