Kinematic Analysis of Different Jump Shots in Elite and Non-Elite Basketball Players
Abstract:This study was focused to analyze the characteristics of kinematic of jump shots between elite and non-elite collegiate basketball players. Eight SBL (Super Basketball League) and 8 collegiate (Class A3) basketball players were participated in elite and non-elite groups respectively. Both groups performed two kinds of basketball shots, dribble jump shot and set shot, which were captured by three-dimensional motion analysis system. Three-dimensional kinematic at each joint of whole body was analyzed to gain peak angular velocity and timing pattern. All values of this study were compared by t-test. Peak angular velocity of upper limb was observed with no significant difference between two kinds of shots in both elite and nonelite players. However, knee and ankle of the lower limb showed higher peak angular velocity for the dribble shot. During set shot and dribble jump shot, peak angular velocity of the right ankle and right knee was greater in non-elite than in elite player (p<.05). The peak angular velocity of the right wrist was greater, as well as, much more delay of time to peak angular velocity was observed in elite than in non-elite player during set shot (p<.05). From this data we concluded that the three-dimensional characteristics of the kinematic of set shot and dribble jump shot in upper limb were similar. The elite player relied on right wrist to execute set shot whereas the non-elite player relays more on right knee and ankle. (Full text)
