This paper discusses the causal factors behind the occurrence of sports injuries in athletic training and proposes relevant analyses. Firstly, the definition of sports injuries is provided, followed by a classification of common types of sports injuries. Subsequently, an analysis is conducted on the factors that influence the occurrence of sports injuries, including individual, sports-related, and environmental factors. By understanding these influencing factors, it is possible to better prevent and manage sports injuries. Furthermore, the mechanisms behind the occurrence of sports injuries, both acute and chronic, are discussed. Finally, strategies for the prevention and management of sports injuries, including preventive and managerial approaches, are proposed. Through an exploration of the causal analysis and relevant strategies for sports injuries, this study aims to provide guidance for the safety and effectiveness of athletic training.
