Abstract
Three-dimensional kinematic data were obtained from 15 male wheelchair basketball players performing a successful free throw. Players were divided into two groups, according to their International Wheelchair Basketball Federation (IWBF) classification (Group 1: 2-2.5 point players and Group 2: 4-4.5 point players). The angle of release of the ball was 58 for both groups. Group 2 released the ball from a significantly greater height than Group 1 (1.57 - 0.12m v 1.78 - 0.17m; p < .05). Although nonsignificant, the following trends were found: Group 1 showed greater ball release speeds and generated greater angular velocity of the wrist at release while Group 2 generated greater shoulder flexion angular velocity at release. In conclusion, players from different IWBF classes tend to rely on different kinematic strategies to produce successful release conditions.
