Experimental Study On The Influence Of Different Exercise Interventions On Adolescent Female Body Shap

Exercise intervention is according to a certain exercise program,through the appropriate exercise load,exercise intensity and frequency to carry out planned intervention on the subjects for a period of time,to achieve the expected purpose of intervention.There are many ways of exercise intervention,such as high strength interval training(HIIT),resistance training,aerobic training and so on.Through exercise intervention,the body shape of the subject can be changed.This topic is the application of the above several exercise intervention methods,the adolescent female body shape changes for the relevant experimental research and discussion.By using the methods of literature,experiment,logical analysis and mathematical statistics,the influence of exercise intervention on adolescent female body form was taken as the research object.The students in Jilin Girls’ School were selected as the experimental group(HIIT group)(20 persons)and the aerobic combined resistance training group(20 persons),with a total of 40 persons as the experimental objects.In this study,the exercise intervention of high intensity interval training(HIIT)and aerobic training combined with resistance training was selected,and two sets of different exercise intervention programs were designed.Under the intervention of two different programs,the influence of the two exercise interventions on the body form of adolescent female was explored,and the changes in the body form of adolescent female were analyzed according to the experimental results.The following indexes reflecting body shape were selected: body weight,BMI,water percentage,fat content,basal metabolic rate,muscle content,waist circumference,hip circumference,waist-to-hip ratio,thigh circumference,upper arm circumference,abdominal skin fold thickness,scapular skin fold thickness.Through exercise intervention and experiment test,the relevant research and analysis are carried out.The results show that:1.The adolescent female body shape of experiment group 1 and experiment group2 showed good adaptive changes before and after the experiment.That is,the BMI value and fat content decreased after the experiment,and the changes showed highly significant differences.Compared with the experiment group two,the experiment group one underwent HIIT exercise intervention had a more obvious effect on reducing BMI.2.After the experiment,the waist circumference and hip circumference of adolescent female in experiment group 1 and experiment group 2 decreased,but the change was not significant difference;In terms of upper arm circumference and thigh circumference,the changes were significantly different.Compared with experimental group 2,the effect of HIIT exercise intervention on upper arm circumference and thigh circumference was more obvious in experimental group 1.3.After the experiment,the abdominal skin fold thickness of adolescent female in experiment group 1 and experiment group 2 decreased,and the change was not significant difference;There was a significant difference in the reduction of shoulder pleat thickness.Compared with the first group,the effect of aerobic combined with resistance training exercise intervention on the reduction of shoulder pleat thickness was more obvious in the second group.4.After the experiment,the moisture rate of adolescent female in experiment group1 and experiment group 2 increased,and the change was not significant difference;There were significant differences in the improvement of basal metabolic rate and muscle content.Compared with the experimental group 1,the effect of aerobic combined with resistance training exercise intervention in the experimental group 2 was more obvious in improving the basal metabolic rate and muscle content.
