Abstract:

By modeling system, movement of female limb joints, skeletal and muscle were analyzed for cycling sports. Five key frames were chosen, the five frames were critical points of joints, skeletal and muscle motion. The method of mask rubbed deformed skin of five key frames and areas were computed by graphics software. The deformation of thigh skin was researched in quantitative and qualitative. The experiment founds the skin of hip is stretch and the rate of stretch reaches 58% in the area of hip fold. The skin shrinkage of oblique area near groin increases gradually, shrinkage rate reaches 50%. Skin deformation of anterior thigh is bigger than posterior thigh. It provides theoretical basis for specific loose measurement design of each partitioning area of the cycling trousers and the fabric selection. 

Key words: cycling motion, skeletal muscle simulation, female lower limb, skin deformation
