An Experimental Study Of The Effects Of Elastic Band Exercises On The Physical Fitness Of Primary School Students Aged 9-11

The physical fitness of primary school students has always been the focus of national and social attention,and their physical fitness is in these rapid development periods.At this stage,their physical fitness directly affects their future work and life.Therefore,it is also the focus of national and social attention.However,in recent years,the current decline in the physical fitness of primary school students in China is worrying.How to improve the physical quality of primary school students safely and effectively is also a research hotspot of many scholars.The purpose of this study is mainly to introduce elastic bands into elementary school physical education classes.Starting from the actual teaching of physical education in elementary schools,we discuss the changes in physical fitness of primary school students after using elastic bands.In this study,the effect of elastic band exercises on the physical fitness of 9-11 year old pupils is taken as an object.The third and fourth grade students of Huoying Central Primary School in Changping District,Beijing are used as experimental objects.The elastic band exercises are used to improve the physical fitness of primary school students.This article mainly uses comprehensive research methods such as literature data method,expert interview method,experiment method and mathematical statistics method to get the following research conclusions.(1)The elastic band is easy to carry and use,is relatively light,and will not be affected by the venue and the weather.It is suitable for introducing into the physical education classroom of the primary school and improving the physical fitness of the pupils.(2)After 16 weeks of experimental intervention,the test indicators of the students in the control group and the students in the third and fourth grades all showed different increases.The main reason for this stage is the sensitive period of the physical development of primary school students.At this stage,students taking appropriate amounts of physical exercise will further promote physical growth and development.(3)The elastic band practice helps to improve the speed quality,muscle endurance and flexibility of the third and fourth grade students.It has little effect on coordination and cardiopulmonary function.(4)After 16 weeks of experimental intervention,the improvement of the speed and quality of the fourth grade students is more obvious,while the muscle endurance and flexibility of the third grade students are more improved.
