In the 1920s and 1930s, Professor Ma Yuehan believed that physical education was a theoretical science that went deep into practice. It involves physiology, psychology, medicine, anatomy and other disciplines. Although exercise is inseparable from exercise, exercise is not equal to exercise. Working people engage in manual labor, but manual labor cannot replace sports. Ma Yuehan believes that some people in social places have incorrect views on sports. On the one hand, some people don't understand that sports is a science; On the other hand, people engaged in sports work don't know enough about sports, and they don't feel that they have a deep understanding of sports.

Physical education is a science to enhance physical fitness. It specializes in sports activities, so that a person's body can reach the highest sound level in all aspects. Physical education is based on various sciences. Sports is used to deal with a person's physical development. In order to achieve the goal of physical education, we must master and be familiar with many scientific theories and knowledge in order to develop and strengthen our bodies correctly.

If you want to practice equipment and run and jump, you must master the scientific foundation. First of all, we should be familiar with physics, sports humanities, psychology and physiology, so as to better develop sports and improve technology. In order to enhance a person's heart function, we must first be familiar with anatomy, student science, medicine and so on. And then take appropriate exercise according to your personal situation. For example, we don't have a good scientific basis for what is wrong with sports. In order to make teaching and training scientific, he made a comprehensive and in-depth scientific analysis and research on physical education.

Ma Yuehan applied for Tsinghua in his early years. He made a scientific study on the relationship between physical development and physical exercise of middle school students and the effect of physical exercise on the nervous system. He is very interested in sports policies, principles, organization, personnel training, teaching and training, sports research and physical exercise. He has long had a scientific theory on personality training, and his reasoning is profound, clear and thorough. For example, Mr. Ma attaches great importance to students' physical development and health, and has implemented a series of measures such as physical fitness measurement, physical examination, physical fitness measurement and physical fitness test, and conducted comprehensive inspections and tests on students every year, and established detailed records and files.
