Handball jump shoot kinematics – differences between Croatian elite and professional players

The main goal of this study was comparison of Croatian elite handball players with players that participate in Croatian premier handball league in the kinematic parameters of jump shoot. The kinematic analysis was conducted by GAIT – LaBACS software system. Five groups of variables was used, totally 25 kinematic parameters. Every variable group corresponded to 5 phases of jump shoot performance: run-up, take-off, flight, throw, and landing. The differences between elite and professional handball players were analysed by multivariate and univariate variance analysis. MANOVA results show significant differences between the groups (λ=0.01. F=10.29. p=0.02) and also between two phases of jump shoot performance ; run-up (λ=0.43. F=2.83. p=0.03) and flight (λ=0.34. F=8.1. p=0.00). Differences observed in this study are most probably influenced by different level of handball demands. Elite players play faster and with more optimal technique that force them on minimal number of steps during run-up phase. Speed of the game demands better perception that influence more extended body position during attacking and shooting movements. Players of lower quality compensate morphological deficiencies with different jump shoot technique. It demands more power for jumping higher and longer, especially during use of jump shoot in breakthrough situation. These players, also set ball on higher position during throwing movement which is another compensation mechanism that can give shorter players advantage against higher defenders.
