Research on the prevention strategies of sports injuries in physical education teaching through sports biomechanics analysis

Sports activities induce significant changes in cell mechanics. Physical exercise prompts molecular adaptations in muscles, and analyzing the biomechanics of specific sports is crucial. Sports injuries, commonly occurring during exercise, often stem from overuse, crashes, or excessive forces. The physical and psychological rigors of sports and intense competitions heighten the risk of damage. For instance, hamstring strain injury is prevalent among football players. Understanding the biomechanics underlying such injuries is essential. This research focuses on gathering biomechanical data from physical education exercises, including joint angles, forces, velocities, and muscle activations. By preprocessing this data through cleaning and normalization, we aim to decipher the molecular and cellular level changes. Maximal hamstring flexibility and muscular tightness, identified as key factors, can provide insights into muscle cell mechanics and potential injury prevention. A novel Intelligent Flamingo Optimized Residual Network50 (IFO-ResNet50) is proposed. Through biomechanics analysis in physical education teaching, it targets the prevention of football muscle injuries. The method’s effectiveness is evaluated in terms of accuracy (98.1%), recall (98.4%), F1-Score (98.2%), AUC (98.5%), and precision (98.7%) in comparison to existing algorithms. This research not only aids in identifying the physiological and biomechanical changes at the cell or molecular level due to sports but also offers practical strategies for physical education teachers. By reducing injury risks, it can enhance student safety and performance in school sports programs, thereby contributing to a more comprehensive understanding of the relationship between sports and cell mechanics.
