Abstract
The purpose of this study is to identify how the human body’s joints work together in producing the ideal release angle and initial velocity of a basketball during jump shooting and how these joint movements change with distance and subject’s skill level. We hypothesized advanced shooters would show less variability in their movements than novice and intermediate shooters. We also hypothesized there are a variety of release angles and velocities that could lead to a successful shot at any given distance. Fifteen young adults were recruited for this study among three different skill levels: novice (5), intermediate (5), and advanced (5). Each subject’s joint angle, joint velocity, and joint accelerations were tracked across 50 trials at 10 different distances from the hoop, with 5 trials occurring at each distance. Release angle and initial velocity of the ball were also determined. The subjects were recorded from the side with a Sony Rx 100 Mk. V camera. Tracking was done with Deep Lab Cut and joint analysis was done in Matlab. The results indicate a pattern between joint variability and expertise. Novices showed more joint variability than advanced shooters. We also found that there are variety of combinations of initial release angles and velocities that lead to a successful shot. This study provides some insight into how being able to control your movements (less variability) is beneficial into leading to more consistent successful jump shots. This idea can be implemented into training techniques to help players become better at jump shooting.
