Study On The Influence Of Physical Education Class On The Healthy Development Of Middle School Students During The Normalization Of Epidemic Situation

Since the emergence of the new crown epidemic,the epidemic has brought many conflicts to all walks of life.The teaching activities of school education were forced to switch to online teaching due to the outbreak of the epidemic,and students spent more time using electronic equipment,staying at home and sedentary behavior.During the period of epidemic normalization,the teaching form is mainly a mixture of online teaching and offline teaching.The quality and continuity of teaching activities in physical education class can not be guaranteed,and the scope of students’ learning and living environment has become smaller,which has a certain negative impact on students’ physical and mental health.This paper studies the influence of physical education class on students’ physical health development during the period of epidemic normalization,in order to provide reference for students’ personal physical health development in physical education class during the extraordinary period.This study uses the methods of literature,questionnaire,interview,observation and mathematical statistics.By searching literature,we can master the changes and development trends of school physical education and physical education class teaching,and clarify the goals and requirements of the current curriculum standards for school physical education.Through sorting out,counting and analyzing students’ physical health test data,vision test data,interview content and questionnaire.The results are as follows:(1)During the epidemic normalization,the students’ physical health level changed with the increase of students’ grades.Among them,the excellent rate of female students’ body mass index increased by 0.4%;The excellent rate of sitting forward flexion increased from 10.1% for boys to 15.0% and from 14.2% for girls to 19.8%.The excellent rate of pull-ups increased from 3.8% to 5.4%.However,the excellent rate of other projects has decreased to varying degrees;Only pull-ups and sit-ups have increased the good rate of physical fitness test,while other items have decreased to varying degrees.(2)The detection rate of students’ visual myopia.The normal rate of students’ right eye vision is 10.6%,and the normal rate of left eye vision is 16.8%.The normal rate of right eye vision and left eye vision of 2020 students is 17.1% and 21.8%,respectively.The normal rate of right eye vision and left eye vision of students in grade 2021 was 15.3%and 19.9%,respectively.In the second vision examination,the detection rate of normal vision decreased to varying degrees.(3)During the period of epidemic normalization,there is a big shortage in physical education class in terms of students’ health behavior,the cultivation of sports morality,the mastery and application of sports skills,and the participation of physical education class.Through the analysis of the research results,the following conclusions are drawn:(1)During the period of epidemic normalization,physical education class’ s role in promoting students’ physical fitness weakened with the increase of students’ grades;Physical education class’ s promotion effect on students’ healthy behavior and sports morality is not ideal.(2)Teachers’ role in promoting students’ health under the online and offline mixed teaching mode during the epidemic normalization period is relatively small;Teachers need to be more active in updating their teaching professional ability and dare to practice and apply new ideas and methods in teaching practice.(3)Students’ participation in self-management,the application of exercise methods and online physical education class is relatively low in the environment of lack of teacher supervision during the epidemic normalization period.
