Contributions of the Selected Fundamental Factors to Basketball Performance for Paralympic Wheelchair Basketball Players. (Biomechanics)

Article excerpt

The movement dynamics and physical profile specifically related to handling a wheelchair, such as starting, sprinting, braking, turning and blocking are crucial to wheelchair basketball (WCB) performance. The movement dynamics and physical profile for WCB players are dependent on fundamental factors such as muscle strength and range of motion (ROM) of the upper extremity, the reaction time, and the upper body segment length. The purpose of this study was to determine the contributions of the selected fundamental factors (arm length, sitting height, simple reaction time (SRT) and choice reaction time (CRT), muscle strengths and ROMs at the shoulder, elbow, and wrist joints) to the WCB performance (average points, rebounds, assists, blocks and steals per game in the season statistics, and the coaches' evaluations) for Paralympic WCB players. Thirty-seven Paralympic WCB players (M age: 28.75 [+ or -] 7.52 years, M body mass: 58.95 [+ or -] 12.24 kg, and M time of playing-WCB: 9.75 [+ or -] 6.68 years) from seven countries participated in this study. A self-developed computerized reaction time system was used to test the SRT and CRT. The ROMs and the muscle strengths at the shoulder, elbow, and wrist joints were measured by a plastic goniometer and a MP DA100B BioPac force measurement system, respectively. Stepwise regression analysis was used to identify the contributions of these fundamental factors, and the "dimensional variables" (DV) derived from the fundamental factors to the WCB performance. …
