摘　　要：使用三维运动捕捉设备采集了8名B罩杯女性裸胸状态下无绳跳绳时的乳房运动坐标,计算乳房竖直相对位移,并与裸胸跑步时乳房竖直相对位移进行对比,同时分析了无绳跳绳和有绳跳绳产生的乳房竖直相对位移曲线和速度曲线。结果表明:无绳跳绳时的乳房竖直相对位移小于跑步时,且无绳跳绳与有绳跳绳的运动学参数不同。为进一步探究模拟跑步的运动假人是否能模拟跳绳运动,还须对比穿着文胸状态下跑步和无绳跳绳时的乳房竖直相对位移,以及裸胸时跑步与有绳跳绳时的乳房竖直相对位移。Three-dimensional motion capture system was used to collect the breast displacement coordinates when 8 participants with B cup were rope skipping in no bra condition.Then the coordinates were calculated to get the vertical relative breast displacement,which was compared between rope skipping and running.And the vertical relative displacement and speed curves of breasts between ropeless skipping and rope skipping were analyzed.The results show that the vertical relative displacement of breasts when ropeless skipping is less than running,and the kinematic parameters are different between ropeless skipping and rope skipping.In order to explore whether the dynamic mannequin,which can simulate vertical breast displacement in running,can simulate rope skipping or not,it is necessary to compare the vertical relative breast displacement in bra condition between running and ropeless skipping,as well as the vertical relative breast displacement in no bra condition between running and rope skipping.
