Application of sports biomechanics in improving the technical level and reducing sports injuries in athletes

This paper focuses on the field of sports biomechanics, and deeply explores its key applications in improving the technical level of athletes and reducing the risk of sports injury. Using rugby and football, two highly representative sports, the underlying internal link between athletes’ skill level and sports injury. It has been found that gender differences in athletes and the range of exercise have different effects on the range of exercise in their muscles and joints. In studies of sport football, the data show distinct sex differences. In the male experimental group, the Angle and torque of the knee plane decreased, and those in the ankle decreased more significantly, while in the female experimental group, the knee angle increased slightly, and the ankle Angle and torque increased to varying degrees. This change shows that the adjustment of sports mechanics of the football players has a positive effect, especially male athletes, the movement significantly reduced, effectively reduce the risk of injury, fully proved the sports mechanics adjustment in reducing the key value of injury rate, help athletes to maintain good physical condition in training and competition, reduce injuries. In the study of rugby movement, in terms of hip frontal torque, the female experimental group was 8.73, which is lower than the female control group. This data intuitively shows that the female experimental group has lower damage in this dimension, reflecting that the adjustment of motor mechanics also plays an important role in rugby movement.
