| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系 === 106 === Most of the previous studies related to jump shot focused on shooting distance and the influence of defenders rather than pull up jumpers. According to the analysis of the 2017 NBA Finals, dribbling past an opponent and “catching and shoot” were the main players’ techniques; players dribble past their opponents and jump shot with 1-2 step. The purpose of this study was to compare the difference among the movements of the “left-hand dribble and shoot”, “right-hand dribble and shoot”, “left-side catch and shoot” and “right-side catch and shoot” on the 3 points line in biomechanical approach. Eight Taiwan UBA (University Basketball Association) division one were served as the participants. Seven VICON infrared cameras (300Hz) and a JVC high-speed camera (300Hz) were used to collect the dynamics variables in the experiment. The dada were calculated by the software of the Visual3D and the Kwon3D. All the variables were tested by Friedman two-way ANOVA non-parametric statistical test and the post-hoc comparison were calculated by SPSS 23.0, the significant levels as α = .05. The results showed the step length of “dribble and shoot” was longer than “catch and shoot”; the horizontal COM velocity at the landing point of the pivot foot in “dribble and shoot” was faster than “catch and shoot”. The time of COM descending phase was shorter in “dribble and shoot” than in “catch and shoot”. The results showed that the angular velocity of knee-joint, the vertical velocity of the COM was faster and the jump height was higher in “dribbling and shooting” than “catching and shooting” movements. The differences between the “dribble and shoot” and the “catch and shoot” was greater than the difference between using left hand and right hand or the two cutting directions. There were no significant kinematical differences in the upper limbs among the four movements.
