점핑-착지 시 착지거리에 따른 최대수직 지면반력과 요구 마찰계수의 시간관계 = The Relationship among Temporal Variables between Peak Vertical Force and RCOF according to the Landing Distance during Jumping-Landing

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze on relationship among temporal variables between peak vertical force and coefficient of friction(RCOF) required according to the landing distance during jumping-landing. They were divided into 3-types of landing distance(25 cm, 40 cm, and 50 cm) on wood box of 40 cm heights. As a result, the following conclusions obtained were as follows. The time of occurrence showed significant statistically with more shortened in RCOF max than that of peak vertical forces. Peak vertical forces showed significant statistically higher forces according to increase of landing distances. Loading rate didn``t show significant differences statistically according to landing distances, but, 50 cm showed higher loading rate than that of 40 cm and 25 cm during drop landing. RCOF showed significant differences statistically according to landing distances. But, RCOF max showed higher according to increase of landing distance during drop landing.
