摘要:


文题释义:
全脚触地模式:受试者在引拍和挥拍击球期间确保右脚的脚跟着地,整个脚掌尽可能与地面产生接触。
正常触地模式:作为对照条件,受试者按正常动作习惯自由发挥。

背景:探讨基于步法的足部触地模式对乒乓球运动中下肢关节运动特征的影响,可为指导下肢训练提供科学依据。
目的:对比乒乓球运动中不同触地模式下的运动学和动力学差异。
方法:使用动作捕捉和三维测力台同步采集17名专业乒乓球运动员在正常触地和全脚掌触地模式下优势侧下肢的运动学和动力学数据。配对样本t检验用于分析关节角度、地面反作用力、关节反作用力和关节力矩等离散指标的统计学差异;统计参数映射用于分析足底压力中心移动轨迹和膝关节力矩等时间序列数据的统计学差异。
结果与结论:①正常触地模式下的膝关节内翻、侧向地面反作用力、膝关节垂直反作用力和伸膝力矩峰值显著高于全脚掌触地模式;②在足底压力中心移动距离中的89%-91%运动阶段,正常触地模式压力中心显著远于全脚掌触地模式;③在X轴力矩曲线中的23%-38%运动阶段,正常触地模式的伸膝力矩显著大于全脚掌触地模式;④在Y轴力矩曲线的8%-18%运动阶段,全脚掌触地模式显著大于正常触地模式。通过对比不同触地模式的下肢生物力学特征值和统计参数映射分析结果,认为全脚掌触地模式可能是影响乒乓球运动表现的重要因素。乒乓球运动中需要针对性地对触地模式进行调整和练习,避免使用全脚掌触地模式,提升乒乓球运动者下肢运动能力。

Abstract: BACKGROUND: Exploring the effects of foot contact patterns based on footwork on the joint movement characteristics of human lower limbs in table tennis can provide a scientific basis for guiding lower limb training.
OBJECTIVE: To analyze the differences in kinematic and kinetic characteristics of table tennis athletes under different ground contact patterns. 
METHODS: Motion capture system and three-dimensional force platform were used to synchronously collect kinematic and kinetic data of the dominant side lower limb of 17 professional table tennis athletes in normal foot contact pattern and full-foot contact pattern. Paired t-tests were used to analyze the statistical differences in discrete metrics such as joint angles, ground reaction forces, joint reaction forces, and joint moments. Statistical parametric mapping was employed to analyze the statistical differences in continuous time-series data, such as the movement trajectory of the center foot of pressure and the knee joint moments.
RESULTS AND CONCLUSION: (1) In the normal foot contact pattern, knee internal rotation, lateral ground reaction force, knee vertical reaction force, and knee extension moment were significantly higher than those in the full-foot contact pattern. (2) In the 89%-91% movement phase of the distance traveled by the plantar center of pressure, the center of pressure in the normal foot contact pattern was significantly farther away from that in the full-foot contact pattern. (3) In the 23%-38% movement phase of the X-axis torque curve, the knee extension moment in the normal foot contact pattern was significantly higher than that in the full-foot contact pattern. (4) In the 8%-18% phase of the Y-axis torque curve, the knee extension moment in the full-foot contact pattern was significantly higher than that in the normal foot contact pattern. By comparing the difference in lower limb biomechanical characteristics between different ground contact patterns and statistical parametric mapping analysis results, the full-foot contact pattern may be an important factor affecting athletes’ performance. It is necessary to adjust and practice the touch patterns to avoid the use of full-footed touch patterns to improve the lower limb athletic ability of table tennis athletes.
