In order to solve the problem of athletes with lower limb movement injuries in table tennis footwork, with the increasing risk of sports, the incidence of acute injury also increased. The increase in athletic training, on the one hand, improves the skill level of the athlete; on the other hand, it increases the chances of more chronic injuries. Through the investigation of the injury site of 143 table tennis players, the researchers found that the lower limb injury accounted for 32% of the total injuries and the upper limb injury rate accounted for 33.14% of the trunk, accounting for 34.29%. The injury sites are mostly concentrated in the lumbar region, followed by the shoulders and knees. Through epidemiological research on the injuries of outstanding table tennis players, the survey results show that the probability of lower extremity injuries ranks in the top three, and most of them are acute sprains and chronic strain injuries. By applying the principles of sports biomechanics, a biomechanical analysis of the asynchronous foot movement in table tennis is proposed; from three aspects of kinematics, dynamics, and plantar pressure, it is found that the injury of table tennis is closely related to technical play connect. The risk of sports injury is inevitable in a sense, due to the long-term local overload, which causes the strain of the sports system. In order to avoid or reduce the occurrence of such sports injuries, coaches should standardize the technical movements of the players and arrange the exercise load reasonably according to the characteristics of the sports.
为了解决乒乓球运动员下肢运动损伤的问题，随着运动风险的增加，急性损伤的发病率也有所增加。一方面，运动训练的增加提高了运动员的技能水平；另一方面，它增加了更多慢性损伤的机会。通过对 143 名乒乓球运动员受伤部位的调查，研究人员发现，下肢损伤占总损伤的 32%，上肢损伤率占躯干的 33.14%，占 34.29%。受伤部位主要集中在腰部，其次是肩部和膝盖。通过对优秀乒乓球运动员受伤情况的流行病学研究，调查结果显示，下肢受伤概率排名前三，且多为急性扭伤和慢性劳损。通过应用运动生物力学原理，对乒乓球中不同步的足部运动进行了生物力学分析；从运动学、动力学和足底压力三个方面发现，乒乓球的损伤与技术动作衔接密切相关。从某种意义上说，运动损伤的风险是不可避免的，由于长期局部超负荷，导致运动系统的劳损。为了避免或减少此类运动损伤的发生，教练员应根据运动特点规范运动员的技术动作，合理安排运动负荷。
