Kinematics Analysis of successful and unsuccessful free shot of Oman’s Wheelchair Basketball Team.

Abstract

This study aimed to identify the values of the parameters kinematic variables of the free shot of Oman’s Wheelchair Basketball Team, and to identify the differences between the values of the kinematic variables of the successful and unsuccessful free shot.The researchers used the descriptive approach to suit the study problem. The study sample included (9) fourth-ranked players from Oman's wheelchair basketball team. The researchers used a Canon EOS 250D video camera with a frequency of (25) images per second, in addition to the kinetic analysis program (Kinovea) that used to analyze the kinematic variables of the free shot.The results of the analysis showed that the average values of the kinematic variables for a successful free shot were as follows (The horizontal velocity of the ball launch was 4.99 ± 0.20 m/s, the vertical velocity of the ball launch was 6.81 ± 0.20 m/s). s, the resulting velocity of the ball launch was 8.45 ± 025 m/s, the height of the ball from the ground at the instant of launch was 174.85 ± 7.90 cm, the launch angle was 53.76 ± 2.26 degrees, and the maximum height of the ball in flight was 2.37 ± 0.25 m,).The results of the study showed that there were statistically significant differences between the successful free shot and the unsuccessful free shot in the following variables (the resultant velocity of the ball launch) in favor of the unsuccessful free shot, (the height of the ball at the instant of launch) in favor of the successful free shot, while the results did not show any significant differences in the rest of the study variables.
