An Exploratory Study On The Influence Of Sports Load In Physical Education And Health Classroom On The Physical And Mental Health Of Senior High School Students

Exercise load is an important index to measure the teaching quality of physical education and health.Appropriate exercise load can effectively promote the development of students' physical and mental health.On the one hand,the existing research on sports load in physical education and health class mainly explores the current situation and reasons of sports intensity and sports density in physical education and health class through investigation and research,and rarely explores the impact of different sports load in normalized physical education and health class on students' physical health;On the other hand,a few experimental studies mainly explore the impact of exercise load on students' physical health level,and less explore the promotion of students' mental health level;Moreover,different studies have different criteria for determining the appropriate exercise load.Therefore,this study attempts to investigate the different exercise load stimuli obtained by students with different classroom participation in senior high school physical education and health class,summarize and refine the appropriate exercise load range combined with literature and interviews,and explore the impact of appropriate exercise load in physical education and health class on senior high school students' physical and mental health through experiments.This study adopts the methods of literature,questionnaire,interview,experiment and mathematical statistics.40 people are selected from some classes of grade one of senior high school in Sucheng No.1 middle school.Through the analysis of the changes of students' physical health level,the suitable exercise load range of physical education and health class is extracted.Then 40 people(22 girls and 18 boys)in the volleyball optional class of grade 2 of Sucheng No.1 middle school were selected as the experimental objects.Through the exercise intervention in the appropriate exercise load range,the effect of the appropriate exercise load in physical education and health class on the physical and mental health of senior high school students was verified.Through the above research,the following conclusions are drawn:1.The suitable exercise load for high school physical education and health class is HR?160-40 min,that is,the average heart rate range of each class is 140-160 beats /minute.2.Appropriate exercise load in physical education and health class can effectively improve the physical health level of senior high school students,especially for students' cardiopulmonary endurance,flexibility,speed,endurance and lower limb strength.3.The appropriate exercise load in physical education and health class has a certain positive impact on the mental health of senior high school students,which can effectively alleviate interpersonal tension,sensitivity and hostility.
