English Abstract

It had been executed the new international basketball rules on October 1, 2010. The three-point line extended the distance from the original 6.25 meters to 6.75 meters. According to the press reported that the SBL basketball game adopted the new basketball rules and had caused reducing three-point shooting frequency in Taiwan. The coaches and the players had expressed that the long distance shooting is indeed more difficult and change jump-shot motion pattern. The purpose of this study is to know the kinematics and dynamics differences of the jump-shot motion in three-point line, old three-point line and free-throw line, which can provide the useful information. Methods: This study recruited eight Taiwan college basketball team players as the subjects to perform jump shot in three kinds of distance. We used ten Vicon infrared cameras (250Hz), one FASTEC high-speed camera (125Hz) and one Kistler force plate (1000Hz) to collect the basketball jump-shot movement from preparatory action to landing movement. By using SPSS 19.0 statistic software to calculate the Freeman two-way analysis of variance by ranks and Pearson product-moment correlation to compare the kinematics and kinetics variables among three jump shots. The significant level was at α = .05. Results: The motion parameters of jump-shot in the new, old three-point line and free-throw line were no significant differences, but the new three-point line motion parameters have a tendency toward greater value. There were significant differences between the new three-point line and free-throw line in the movement variables. Conclusion: There was a trend that the basketball players should reduce jump height and increasing the forward horizontal displacement when they executed the new three-point jump shot movement. We recommend that if the play wants to perform the jump-shot in the New Three-point Line, the players must increase the release velocity, reducing release angle, reducing the time from crouch to release, increasing the upper-limb joint angular velocity and the speed of take-off center of gravity to help shooting. Therefore, it has occurrence of reducing jump height and increasing the forward horizontal displacement.
