摘要
本文探讨了专业乒乓球运动员与新手乒乓球运动员在执行跨步动作时膝关节的生物力学差异.实验招募了18名男性运动员,通过Vicon动作分析系统和高速摄像机同步捕捉运动学与动力学数据.分析结果表明,两组在膝关节屈伸、内外翻及内外旋等参数上存在显著差异.专业运动员在动作执行中显示出更优的膝关节控制和负载分配,减少了运动伤害的风险,提高了动作效率和预测对手动作的能力.这些发现为针对性训练提供了科学依据,有助于优化训练和比赛策略,同时促进乒乓球运动技术的提高.
Abstract
This article explores the biomechanical differences of the knee joint between professional and novice table tennis players during hip step movements.18 male athletes were recruited for the experiment,and kinematic and dynamic data were synchronously captured using the Vicon motion analysis system and high-speed cameras.The analysis results indicate that there are significant differences between the two groups in parameters such as knee flexion and extension,medial and lateral rotation,and medial and lateral rotation.Professional athletes demonstrate better knee joint control and load distribution during movement execution,reducing the risk of sports injuries,improving movement efficiency,and the ability to predict opponent movements.These findings provide scientific basis for targeted training,help optimize training and competition strategies,and promote the improvement of table tennis skills.
