| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系在職進修碩士班 === 98 === Purpose: To find the shooting sequence and to compare the differences of the shooting kinematical variables between Jump and Set Shots. Methods: The high speed video camera photographed and recorded the shooting parameters of 10 graduating 9th grade male students who performed Jump and Set Shots at 4.25m and 5.25m. 5 successful shooting of each shot type were performed at 2 distances. The Kwon3D was used to analyse the image and the SPSS 13.0 was used for two way ANOVA and correlation statistics. The parameters included: 1.the shooting sequence of upper and lower extremities; 2. the differences of the shooting time, squat time, angular displacements and velocities of, the wrist, elbow, shoulder, hip, knee, and ankle joints; and 3. The correlation between the shooting time , the squat time, and the angular displacements and velocities. The α level was set as .05. Results: 1. The shooting sequence of the joint was from shoulder, hip, knee, ankle, elbow, to wrist. 2. Faster angular velocities of squatting knee, shorter squat time, and larger shooting angular of hip, knee, ankle were found in Jump Shot than Set Jump (p ＜.05). 3. The positive correlation was noted between angular velocity of squatting knee and the angular displacement of the shoulder (p ＜.01). The negative correlations were also found between the angular velocity of squatting knee and angular velocity of elbow (p ＜.05), and between the angular displacement of the shoulder and the angular velocity of elbow (p ＜.01). Conclusion: The results from this study indicated that the basketball shooting was taken from shoulder and then from lower limb to upper limb. Shorter period of shooting, squatting faster and deeper, larger angular of hip, knee, and ankle while shooting, and slower angular velocity of elbow were found in Jump Shot than Set Shot.
