Knee joint is one of the most important joints of the human body. It plays a vital role in basketball, football, volleyball and other sports that need to do repeated jumping and landing in high-speed sports. However, the rate of knee joint injury is high in sports, and knee joint injury often occurs in single leg landing. It is related to the decrease of flexion angle of hip and knee joint on the supporting side, the increase of extension and valgus moment, and the increase of ground reaction force. Kinesio taping has been widely used in the field of sports protection in recent years, but whether it can correct injury-related biomechanical risk factors is still controversial, and there are few studies on the timeliness changes of kinesio taping. Therefore, starting from the above concerns, this study compares the differences in biomechanical characteristics of lower limb joints in knee joints under three conditions : kinesio taping, placebo taping and no taping. At the same time, the changes of biomechanical characteristics of lower limbs before and after taping were observed in order to provide reference for the application of knee joint kinesio taping in sports injury protection.
