登山运动中女子肩臂部位体表尺寸变化规律

Study on Size Changes of Women’s Shoulder and Arm in Outdoor Mountaineering

为了更科学合理地设计女子户外登山服的衣袖结构,文章分析了登山运动过程中女子上半身与手臂部位体表皮肤的变化规律。挑选6个代表性的动作姿态,利用体表画线法对测试者上半身及手臂皮肤尺寸进行测量,分析数据变化规律。实验发现,靠近腋窝的肩臂部位皮肤拉伸变形较大,分析整线最大伸长率,其中靠近后腋点的背宽线达42%,靠近腋底的纵向线达25%以上,在靠近臂根的位置,手臂横向线达到30%以上,经过肘部的横向线和纵向线均大于20%。分析各区段线段变化率,越靠近腋窝的位置,区间线段变化率越大。在进行结构设计时,需要综合考虑满足前后腋点周围的横向、纵向拉伸量以及腋窝底点周围的纵向伸长量。

In order to design the sleeve structure of women’s outdoor mountaineering suits more scientifically and reasonably,the paper analyzed the size changes of the upper body and arms of women during mountaineering.Six representative action postures were selected,and the size changes of the tester’s upper body and arms were measured by lineation-on-body experiment,so as to analyze the laws of data change.Results indicated that the skin of the shoulder and arm near the armpit had a large tensile deformation.The maximum elongation of the whole line was analyzed.Thereinto,the back-width line near the back armpit was 42%,and the longitudinal line near the armpit bottom was more than 25%.The transverse line of the arm was more than 30%near the arm root,and the transverse line and longitudinal line through the elbow were more than 20%.The paper analyzed the change rate of each segment.The closer the position is to the armpit,the greater the change rate is.In the structural design,it is necessary to comprehensively consider the lateral and longitudinal stretch around the front and rear armpit points and the longitudinal stretching around the armpit bottom points.
