The Design And Experimental Study Of The High School Students' Elastic Strength Exercise

With the rapid development of society and the continuous improvement of comprehensive national strength,people's material and living consumption level has been raised,and their physical health level has always been concerned by the state.At present,the physical health of my youth is also the focus of our country's relevant departments.In order to improve the physical health of middle school students,the state has promulgated a series of related policies,which requires vigorously popularizing sports activities,strengthening physical exercise inside and outside class,enriching the forms and contents of sports activities,in order to improve students' physical quality and physical health.The elastic band exercises is based on a fitness exercise,with elastic belt for devices using elastic belt has the characteristics of resistance characteristics,and basic strength exercises combined by elastic band content practice can improve the quality of the power of middle school students and comprehensively improve the physical quality of students.Based on literature study and interviewing method,this thesis studies the elastic band strength exercise's theoretical basis,design principles,guiding ideology,goals and methods.Used over the course of three months,the elastic band strength exercise(self-created)and the "National Aerobics and Dance Regulations"-"elastic band aerobics"(State prescribed set)were studied in comparative teaching experiments and through evaluation questionnaire,experimental questionnaire and the elastic band strength exercise satisfaction and feedback questionnaire on Guangzhou Juxian middle school PE teachers and students.The primary conclusions as follows:1.elastic and healthy operation is a feasible way to popularize a physical exercise in secondary schools.In the course of the experiment,the sports teachers and students in Guangzhou high school are well received.The students are satisfied with the movement content,the difficulty of music,the movement and the connection of the movements.The physical education teachers in the school think that the elastic strength exercise is suitable for the school,the equipment is convenient for the school management and this set of movements can also promote the improvement of the students' strength.2.Elastic band strength exercise can ameliorate the students' body shape and improve their physical function level.In the two indexes of height and vital capacity,the average ring growth rate of male and female in the experimental group was 0.05%,0.03% and 0.42% and 0.75%higher than that of the control group.Among the two items of weight and BMI value,the average ring growth rate of male and female was 1.44% and 3.09%,1.33% and1.53% lower than those of the control group.3.Elastic band strength exercise can improve the comprehensive physical quality of middle school students.Through the exercise of elastic force exercise,the two aspects of strength quality and flexibility quality have been improved remarkably,and good results have been achieved in improving endurance quality,but the effect of improving speed sensitive quality is general.But on the whole,resilience and fitness exercises have a positive effect on improving the physical quality of students.3.The action content of the elastic belt exercise is very pertinent.The average ring growth rate of the test results of both male and female students in the experimental group was higher than that of the boys and girls in the control group,especially in the two indexes,which reflected the strength quality of the ball and the 1min sit ups.The experimental group was 6.77% and 11.07%,7.64% and 9.27% higher than the control group.This shows that the content of resilience and strength exercises is more effective to improve the strength and quality of middle school students,and its action is more targeted.
