骑行运动中男子下肢体表尺寸变化规律

为更好地设计功能性骑行服结构，分析了骑行运动中男子下肢体表皮肤变化规律。挑选出6个具有代表性的骑行动作，利用体表画线实验法对测试者右腿进行测量，得到男子下肢体表数据并分析数据变化规律。实验发现：腿部各部位皮肤拉伸形变复杂且差异性大，变化率在（ -61.10%，110.82%）区间内；腰围线与大腿根围线之间的皮肤形变较为显著，腰围、臀围、大腿根围线的围度变化最显著；在长度方向上，前裆长度减少显著，最小值为-42.01%，到外侧缝线位置减少趋势逐渐减弱，后裆长度增大显著且最大值达61.71%；膝盖的屈伸导致各姿态下膝围区间段的数据变化复杂，且对体长变化影响较大。

Study on size changes of man's lower limb body inriding motion

In order to provide reference for the delearn about Man's lower limb skin change rule during riding was analyzed. The contraction and relaxation of the mrscles of the legs caused a greater change in the surface of the skin, and six typical riding actions were selected, and the testers' right leg size data were measured by lineation-on bodymethod to lbtain man'slower limb body surfacedata and the data change rule was nanlyzed.It is found that, the tensile deformation of the skin of all parts of the leg is complicated and varies considerably, with the wariation rate of-61.10% to110.82%. The skin deformation between the waist line and crotch line is significant, and the biggest one is the changes of the waist line, the hip line and the thigh contour line; in the longitudinal direction, the front crotch reduces the most, with theminimum valueof -42.01%, andthe decreasing trend gradually becomes smaller in the position of the outer side suture; the restcrotch increases the most with themaximumof61.71%; and knee movement causes more complicated changes in the knee line and a greater impact on the body length.
