碩士 === 國立體育學院 === 教練研究所 === 92 === Abstract Jump shot is the most frequent shooting used by basketball players. Two-dimensional video techniques (60 Hz) were used to obtain images of basketball jump shots from free throw line (n=10), as performed by members of the men's quarter-finalist teams at the games of the UBA in Taiwan in 2003. The collected data were analyzed by, one-way ANOVA, and Pearson product-moment correlation. The results indicate that:(1)Jump shot Movement time is 0.97548± 0.2023 sec., (2)Squat Phase 58.1%±0.137 Take-off phase 33.8%±0.124 arm-push phase8%±0.03., (3)Angle of knee100.915∘±17.142.,(4)Ball release timing -0.021±0.081sec., (5)Ball release angle 50.533∘±6.162., (6) The difference between the shot made and missing, on phases percentage of movement time, timing of release ball and angle of release ball are unobvious. (7) The correlation between the shooting percentage and phases percentage of movement time, timing of release ball and angle of release ball are unobvious.
