滯空時間延長을 위한 二重 Jump의 軌跡分析 = The Trace of Wheels' Analysis of Twice High Jump in order to Extend the Flight Time

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the aerial motion of the twice high jump that extend of flight time with kinematical analysis method.
Two male basketball players of O.O.U were used for the purpose of this study. Twice high jump movement preformed by each players were taken by VTR camera. Then all tapes were assembled and analyzed by cinematographical techniques. The results of this study were summerized as follows :
It were two times for each subject's extending flight time in aerial motion and be attend with largely change of motion.
1. Sub. K largely flexed knee joint and shoulder joint at 7-8 situation and largely flexed legs and arms toward C.D.G at 9-10 situation.
2. Sub. Y largely flexed waist joint at 6-7 situation and largely flexed waist joint and shoulder joint at 9-10 situation.
3. Sub. K mainly used his legs and arms to the best advantage.
Sub. Y mainly used his waist to the best advantage.
