First, the education and health departments did not pay enough attention to the school sports health work, did not really put the students' physical health problems on the agenda, and lacked policies and human, financial and material support for the school sports health work.
Second, teenagers lack physical exercise.
Some schools don't attach importance to physical education class, which is manifested in that the curriculum and time schedule can't be guaranteed, the teaching content and training methods are backward, and the exercise effect is not ideal; Extracurricular mass sports activities organized by the school
(including long-distance running activities, class ball games, etc. ) reduced; Students' study burden is heavier, study time is prolonged, and outdoor exercise time is reduced; Due to the increase in the number of only children, it is common for students to be afraid of hardship and fatigue. When participating in physical exercise and choosing exercise programs, we often avoid "heavy" and "light".
In a word, there are some problems such as insufficient school space, backward teachers' equipment, time arrangement and sports activities, and students' lack of willingness to exercise hard. Social prejudice against education, one-sided understanding of teaching quality evaluation and one-sided pursuit of enrollment rate also affect the development of school sports activities.
Due to the above factors, students are deprived of physical exercise to some extent.
