Biomechanical principles in the prevention of sports injuries

Biomechanics, as an interdisciplinary field involving multiple fields, can help analyze individual differences, develop personalized training plans, and effectively prevent injuries to vulnerable areas of athletes. This article used a high-precision 3D motion capture system and various physiological monitoring devices to collect athletes’ motion and physiological data. Combined with biomechanical modeling and risk assessment methods, the impact of five key parameters, step frequency, stride, joint angle, muscle strength, and speed, on injury risk was analyzed. The experimental results showed that implementing the personalized biomechanical prevention strategy applied in this article reduced the incidence of sports injuries by 20%, and optimizing step frequency, stride length, and enhancing muscle strength can significantly reduce the risk of injury. This article provided a scientific basis for developing personalized prevention strategies, which can help improve athletes’ athletic performance and safety.
