What does Professor Ma Yuehan think physical education class should do if it is really effective?

Professor Ma, proceeding from reality and step by step, thinks that the development of human body has certain natural laws. Physical exercise must abide by this law and must not be violated. Otherwise, it will not only fail to improve health, but also damage the body. Everyone should step by step according to their physical condition, and can't fool around! Physical exercise is too small to work. If the amount of exercise exceeds the physical burden, it will produce a certain degree of reaction. So in principle, the amount of exercise must be increased slowly and gradually according to everyone's physical condition. "

Insist on and maintain daily exercise. Professor Ma Yuehan once said, "All the development of the human body is not sudden. It will take a long time to gradually strengthen. Therefore, it is necessary to exercise regularly. If you exercise for a period of time, make progress for a period of time and shrink back for a period of time, your physical progress will not be consolidated. He added: "The exercise time is not necessarily long. It's important to keep practicing. In this way, after a long time, it is good for your health.

"Ma Yuehan's two principles about physical exercise are the guiding ideology of physical education in Tsinghua University today, namely, regular action, reasonable action and scientific action. Professor Ma Yuehan clearly pointed out in the article "Talking about physical exercise with young people" that "sports are interrelated on the basis of various sciences. "... sports are used to promote physical development. In order to achieve the goal of sports, we must master and be familiar with many scientific theories and knowledge.

Therefore, he put forward seven principles of exercise for young students, which is a valuable scientific experience summed up by Mr. Ma in his teaching practice for many years. He stressed that exercise should be based on personal physical condition; Exercise should be based on personal physique; Exercise must be gradual; Exercise must be regular and continuous. American exercise must have goals, plans and steps; Exercise must be combined with all aspects of life; Sports safety; Pay attention to cultivating students' interest in sports and implement the principle of teaching students in accordance with their aptitude.
