It is important to warm the body to avoid sports injuries before exercise. Especially when the weather is colder, people are more likely to obtain muscle damage and other sports injuries if they haven’t done enough warm-up exercise. Therefore, it is a significant issue to teach students to do warm-up exercise in primary school since the first school year. However, in the textbook of Health and Physical education, the content about warm-up is too simple for the students to understand it. As a result, the students may still obtain sports injuries without enough warm-up exercise even though they have received the warm-up classes. Moreover, many athletes stopped their career because of severe sports injury.
In this study, we use information technology to teach the knowledge of warm-up to students in Health and Physical education class. We apply the BioDigital web application to show the 3D structure of human anatomy and to demonstrate the meaning of warm-up exercise for the fifth grade students. The survey from the students shows that the teaching of warm-up with the help of BioDigital can promote the correctness of doing warm-up exercise. It also help to increase the learning motivation of students as well.
