Two dimensional kinematic analysis of jump shot among basketball players on different heights

Abstract

The aim of the study was to investigate the two-dimensional kinematic investigation of jump shot in basketball among three different heights. The variables selected for study were height of CG in shooting stance, player s CG height during at time of ball release, time taken to perform the skill, displacement of CG, releasing velocity of the ball, height of ball release, angles at joint of the ankles, knees, hips, shoulders, wrists, as well as the angle of ball releases, standing height, arm length, leg length and palm length. N=30 (10 in each group) right-handed male basketball players divided into three different groups according to their height i.e. Group I: 160 170cm, Group II: 171-180 cm, and Group III: 181-190 cm or above were selected from NBA Basketball Academy, Indore as the subjects for the study. The data was retrieved using the two specified locations for each successful attempt. (A) The moment of take-off on a jump shot. (B) The moment the ball is released during the jump shot. Two-dimensional method was used for the study and correlation, regression, and one-way ANOVA were used as statistical tools. The variables have implications for understanding the nature of jump-shots in basketball. In correlation analysis, researcher found significant relationships among CG displacement, player s CG height of release ball, height of ball release and left angle of ankle joint, right angle of ankle joint, player height, arm length, leg length and palm length while performing jump-shot in basketball. The remaining selected variables were found to have an insignificant relationship at the jump-shot performance at the time of ball release.
