A Study Of The Effects Of Two Different Forms Of Self Weight Training Methods On The Physical Fitness Of Junior High School Students

Self-weight training is becoming more and more accepted by sportspeople and enthusiasts because of its rich training methods and theoretical system,as well as its simple and easy-to-implement characteristics that do not require high training environment.In recent years,due to the impact of the new epidemic,people’s range of activities has been restricted to a certain extent.Self-weight training has gradually developed from the field of medical rehabilitation to the field of mass sports,and the research results have been further supplemented and expanded through continuous practice.However,relatively little research has been done in the field of school sport on self weight training.The selection of suitable exercise methods to improve physical fitness and enhance the adaptability of the organism is an important task in the teaching of physical education in junior high schools.Therefore,this study takes this as a breakthrough to integrate self weight training into junior high school physical education classrooms.In accordance with the growth and development characteristics of junior high school students,grasp the sensitive period of physical fitness development of junior high school age adolescents,arrange training contents with self weight training and conduct experimental interventions,with the aim of investigating the effects and differences of two different muscle contraction forms of self weight training on the physical fitness of junior high school students.Aim of the study:In this study,according to the different forms of muscle contraction,power and static self weight training contents were selected to intervene on the experimental subjects,two sets of training programs were designed for power and static,two groups were set up,power group and static group,through a 10-week intervention experiment,the scores of various test indexes of the two groups before and after training were obtained,and by comparing the differences between the test scores of the two groups before and after training,the analysis of By comparing the differences in the test scores of the two groups before and after training,we analyzed the changes in the test indexes of the two groups before and after the experiment,so as to know the actual effect of the self weight training on the junior high school students;to explore the effectiveness of the self weight training method in improving the physical quality of junior high school students;to improve the physical health of junior high school students so that these people can have a stronger body and contribute to the society;to find out the suitable self weight training method and exercise intensity for junior high school students to improve their physical quality.Research methods:This study used literature,expert interviews,experimental method,statistical data method and logical analysis methodResearch results:A total of 80 students from two classes in the second year of junior high school in Taiping Town,Bin Hai New Area,Tianjin were used as subjects.A total of 10 weeks of experimental intervention was conducted and the results of the experiment were as follows.1.Strength quality: After 10 weeks of training,both the power group and the static group improved their standing long jump and grip strength scores,but the power self-weight training improved the standing long jump scores more significantly(P<0.01)and the static self-weight training improved the grip strength scores more significantly(P<0.01).2.Endurance quality: After 10 weeks of training,the boys and girls improved more significantly in the 1000 m and 800 m performance(P<0.01),while the static group did not show any significant difference(P>0.05)in the pre-and post-test performance.3.Flexibility: After 10 weeks of training,the post-test scores of both groups did not show significant differences compared to the pre-test scores(P>0.05).4、Balance quality: After 10 weeks of training,both groups showed significant improvement in the test indexes reflecting the balance quality compared with the pre-experimental results(P<0.01),but the effect of static self-weight training on the balance quality was more obvious.5.Speed quality: After 10 weeks of training,the power self-weight training improved the 50 m performance more significantly(P<0.01),while the static group did not show any significant difference in 50 m performance before and after the experiment(P>0.05).6.In terms of agility: after 10 weeks of training,the performance of the power group improved more significantly(P<0.01)in the repetitive crossing event,while the performance of the static group did not show any significant difference before and after the training(P>0.05).Study conclusion:After 10 weeks of self weight training intervention,the self weight training experiment was successfully completed.By comparing the data before and after the experiment,it was found that the power self weight training and static self weight training had their respective strengths in terms of training effects,and compared with each other,the power self weight training was more effective in improving the performance of the standing long jump,which reflects the power strength quality,the800 or 1000 m,which reflects the aerobic endurance quality,the 50 m,which reflects the speed quality,and the repeated crossing,which reflects the agility quality.Static weight training is more effective in improving grip strength,which reflects static strength qualities,and the BOSU ball stability test,which reflects students’ balance qualities.
