Factors contributing to sports injuries include overuse, insufficient conditioning, and poor technique. Overtraining without adequate rest increases the risk of physical strain, while a lack of proper warm-up routines can lead to muscle injuries. Additionally, the use of inappropriate equipment or playing surfaces can exacerbate injury risk. Environmental factors, including extreme weather conditions, can also play a role. Understanding these factors is crucial for designing effective injury prevention strategies and ensuring the longevity and health of athletes throughout their careers.
