Experimental Study On The Effect Of Elastic Belt Exercise On Physical Fitness Of Pupils Aged 11-12 Years

Physical quality refers to all kinds of functions and abilities of human body in all sports,and it is an important standard to measure our physical health.Primary school is a very special age,they are in the transition from childhood to youth,they are in the key stages of physical and physical development.Therefore,this special group needs special treatment in the face of the problem of enhancing physical fitness.In the sensitive period of physical quality,the reasonable exercise of strength has a good effect on the growth of physical fitness of pupils,and the elastic belt itself has some characteristics,which are more suitable for the quality of strength.Relatively weak pupils are trained in strength.Therefore,starting from the reality of the physical fitness of primary school students,this paper introduces the elastic belt practice into the primary school physical education classroom teaching,and applies it to the practice of primary school students' physical fitness.This paper analyzes the influence of elastic belt exercise on improving the physical quality of primary school students,and provides some reference for the application of elastic belt practice in primary school physical education class through this experimental study.In this paper,48 students in Class 1 of Grade 5 and Class 2 of Grade 5 of Liqu Primary School in Zhuozhou City were taken as the experimental objects.Before the experiment,the subjects were randomly divided into experimental group and control group,24 in the experimental group,12 in the male group and12 in the female group,and 24 in the control group,12 in the male group and12 in the female group.After T test,there was no significant difference between the two groups before the experiment.On this basis,the elastic band exercise was carried out for 12 weeks in the experimental group,while the normal class in the control group.After 12 weeks of the experiment,the indexes of 48 students were tested again,and the scores of the students in the experimental group and the control group were analyzed.Results: after 12 weeks of experiment,by comparing the six indexes of physical fitness test,it was found that the scores of physical fitness test of experimental group students and control group students were improved.After T test,there was significant difference in the improvement of strength quality between the experimental group and the control group.Although the flexibility quality,speed quality and endurance quality were improved,there was nosignificant difference between the experimental group students and the control group students after the experiment.The practice of elastic belt has obvious effect in improving the physical quality of primary school students.The practice of elastic belt can be regarded as a way to improve the physical quality of primary school students.
