基于跑步运动中人体下肢皮肤形变的压缩裤分区设计

Partition Design of Compression Pants Based on Skin Deformation of Lower Limbs in Running

为揭示跑步运动中下肢运动姿势的皮肤形变规律,探讨运动压缩裤的结构与人体皮肤形变的关系,运用三维运动捕捉系统采集跑步过程中人体动态变化,对人体下肢运动姿态做定性分析;选取4个关键动作,从横、纵向分析皮肤形变规律。结果表明:在跑步运动周期过程中,腰臀尺寸变化较小,在±3%内波动;腿部横向变化率在(-5.57%,7.26%),纵向变化率在(-15%,15.15%);皮肤纵向变化大于横向,且不同区域的变化存在差异,其中膝盖纵向变化最为明显,变化率最大值达43%左右。压缩裤的结构设计需考虑下肢运动特征,不同区域的皮肤变化量可作为结构设计及面料选择的依据。

In order to reveal the skin deformation law of lower limb movement posture during running,and explore the relationship between the structure of sports compression pants and the skin deformation of human body,the paper used the three-dimensional motion capture system to collect the dynamic change of the human body during running,analyzed qualitatively the posture of human lower limb and selected four key movements,from the lateral and longitudinal structure to analyze the law.The results show that during the running cycle,the size of the waist and buttocks changed little and fluctuates within 3%,the lateral change rate of the legs is in the range from-5.57%to 7.26%,and the longitudinal change rate is in the range from-15%to 15.15%.The change of the longitudinal direction is greater than that in the lateral direction,and there are differences in different areas,the knee longitudinal change is the most obvious,with the maximum change rate about 43%.The structural design of compression pants should consider the movement characteristics of lower limbs,the skin variation in different areas can be used as the basis for structural design and fabric selection.
