Abstract

In this study, we have attempted to create a motion model regarding the timing skills that female skiers need to acquire, based on image analysis data of double poling movements by elite Japanese male and female skiers. As a result, the features of the motion model which could make female athlete A acquire the main skills of the gliding motion of a male athlete as below. (1) Because the muscle power exerted by flexion and extension of the elbow joint and hip joint is efficient, the present joint angular velocity is maintained. (2) The timing is synchronized to let the elbow joint extend in phase P with the time point for maximum angular velocity of flexion of the shoulder joint. (3) The timing is synchronized to allow bending of the elbow joint and hip joint in phase P. In other words, flexion timing is hastened so that maximum angular velocity of hip joint flexion appears with pole grounding approximately at the same time. (4) The timing is hastened to let the hip joint extend in phase G. About after 0.2s at the approximately the time point for maximum angular velocity of elbow joint extension.
