The structure of a class refers to several parts of a class, the order of teaching materials, the organization of teaching methods and the distribution of time. In physical education class, I mainly engaged in various sports activities. Living things have to bear certain physiological loads and have certain intellectual activities. Therefore, the structure of physical education class should not only follow the general laws of human cognitive activities, but also follow the laws of physiological activities. The law of physiological function activities is generally divided into three stages: rising, stabilizing and falling, which reflects the general trend of the change of people's working ability.

According to the above two laws, the structure of physical education class is generally divided into: preparation part, foundation part and ending part. From the following table, we can see the relationship between each part of the course and the three stages of people's working ability (see attached table). The three parts of the above course are the basic structure of physical education class. As for the specific structure of each part, it varies with the specific tasks, teaching materials, students' situation and number, and operating conditions (venues, equipment, seasonal climate, etc.). ). The consistency of the basic structure of the curriculum and the unity of the diversity of the specific structure constitute a complete physical education class structure. In order to strengthen the organization of teaching, physical education class in primary school can also divide the preparation part into two parts: "beginning" and "preparation", which become four classes, and there is no essential difference between them. At present, three-stage courses are widely used. However, in some countries, the structure of physical education class is not strictly divided.
