Abstract
A field study was attempted to biomechanically evaluate four foreign skaters, who participated in the 500m female final round competitionand, and two Korean skaters during the World Short Track Skating Championship. The three dimensional motion analysis with DLT method was executed using four video cameras for analyzing the actual competition situation. In point of analyzing the actual competition situation, it is expected that skaters and coaches have the effective informations, and the following conclusions are drawn; The elapsed time by phase of the foreign skaters appeared shorter than those of Korean skaters, so the start training of Korean skaters should be reinforced. Also the displacement of C.G and foot segment of start phase of the foreign skaters appeared longer displacement than those of Korean skaters. Especially in the starting position, the foreign skaters are superior to Korean skaters in displacement of first(left) and next following stroke(right). The velocity of C.G. and maximum velocity of skate blade of foreign skaters are faster than those of Korean skaters. And the foreign skaters show the superior early velocity change. Both of leaning body angle, and left and right knee angles of the foreign skaters lead to positive point of having the propulsive force in the early starting position. Observing in the most prominent feature of foreign and Korean skaters in start phase, foreign skaters skate quickly the third stroke. These features of Korean skaters would appear the disadvantage of location selection in entering the corner course.
