This study was for examining efficient starting skills and ideal starting pose by analyzing kinematical characteristics of sprint start in roller-skating. For that it targets 6 high-ranking players in each section of middle school, high school, and adults and calculates kinematical data about the point of starting time through three-dimensional cine-photogrammetry. The results of calculating kinematical variables such as the time required at each part, of starting motion, movement of physical center, angle of the legs, angular speed , and so on were as follows： 1. It showed that the shorter necessary time of one step in starting section helped players gel the good record. 2. After the start, the movement of acceleration and deceleration in turn happened repeatedly. And (he good players were faster at the third step than others. 3. In the movement of physical center respect, good players got. the smaller horizontal movement displacement and the lower the vertical movement, displacement. 4. The angle of the lower limbs joint (coxa! articulation, knee joint, and ankle joint.) was enerally large at the starting point, and early starting motion, El and E2. 5. The angle of legs’ speed showed large additional change negative in S6, especially the speed oi the angle of knee joint got the most striking change.
