Javelin throwing is very complicated. It is very important for athletes to master the javelin throwing technology. According to the investigation of athletes' ligament injuries, the preventive measures, treatment methods, rehabilitation methods and analysis were carried out by means of sports anatomy analysis. Through the analysis of Javelin throwers' injuries in sports, this paper uses the biomechanical analysis method to analyze the changes of data in the final exertion stage and the related reasons. The results showed that the injury constituent ratio of 50 national and elite javelin throwers was investigated. Obtain biomechanical indicators, focusing on the analysis of the possible sports injuries and the biomechanical characteristics of the javelin shots in the final stage of exertion. Studies have shown that athletes in the final stage of the force of the javelin shot, the left leg to stretch and stretch may be an important factor in the damage. Research on vulnerable sites should strengthen protective measures, such as strengthening the training of muscle strength in vulnerable parts and improving flexibility, and clarifying the relationship between injury and technical movement during exercise.

标枪投掷非常复杂。对运动员来说，掌握标枪投掷技术非常重要。根据对运动员韧带损伤的调查，通过运动解剖学方法进行了预防措施，治疗方法，康复方法和分析。通过对标枪运动员运动损伤的分析，运用生物力学分析方法，分析了标枪运动员最后用力阶段的数据变化及相关原因。结果表明，对50名全国及优秀标枪运动员的伤害构成比进行了调查。获取生物力学指标，重点是在运动的最后阶段对可能的运动损伤和标枪射击的生物力学特征进行分析。研究表明，运动员在标枪射出力的最后阶段，左腿的伸展和伸展可能是损伤的重要因素。对脆弱部位的研究应加强保护措施，例如加强脆弱部位肌肉力量的训练和提高柔韧性，并阐明运动过程中损伤与技术运动之间的关系。
