Dynamic Changes Of The New Students From The Southeast University In College Physical Education Teaching Reform

College students' physiques have a great impact on the development of the countries. College students should be both mentally and physically healthy, therefore, the understanding of the condition of their physiques, the research on and exploration of the ways to improve their physiques are of great significance. The nation-wide surveys on physiques show that physiques of young people are declining, especially the functions of their hearts and lungs. In order to get a better understanding of the state of college students' physiques, this thesis conducts a comparative analysis on the data, which include height, weight, step experiment, vital capacity, standing long jump, the power of gripping (male) and sit-ups (female), about physiques check of freshmen in Southeast University ever since the implementation of Criteria on Students 'Physiques and Health five years ago. The thesis also makes the survey in the form of questionnaires on PE teaching and physical exercises in high schools, colleges and universities so as to understand the laws and reasons of dynamic changes in college students' physiques and put forwards constructive suggestion on PE teaching reform in colleges and universities.The research shows that: 1. The Southeast University freshmen's physiques are in good condition as a whole, but they are declining yearly, which is more obvious for girl students than for boy students. 2. Both boy and girl students' height and weight increases moderately, the percentage of boy students who tend to be heavier or lighter than the standard weight increases, and the percentage of girl students who are lighter than the standard weight increases. 3. Both boy and girl students' function of heart and lung decreases, and it's more obvious for girls than for boys. 4. The students' explosive force of lower limbs decreases, boy students' force of upper body decreases and girl students' force and endurance of waist and abdominal muscles remain good.In view of current situation and dynamic trend in college students' physiques as well as the existing problems in PE teaching in high schools and colleges and universities, the thesis puts forwards the following suggestions concerning PE teaching reform in colleges and universities: the teaching materials, based on students' interest, should attach great importance to the improvement of their heart and lung functions; the levels of PE classes should match the different levels of students' physiques; considerations should be given to the progresses students make in PE study when evaluating students; and guidance should be given through PE theory courses to enable students to exercise scientifically.
