Sažetak
The aim of this study was to determine whether the dynamic motor stereotype of movement (shooting technique) is violated under conditions of an increased lactate concentration in a player's blood after a 30–15 intermittent fitness test. The hypotheses was that there would be statistically significant differences in ball speed and shooting accuracy in jump shots on the goal before and after the occurrence of fatigue in the player. The sample of respondents consisted of 10 top-level handball players of the highest competition rank in Croatia. The results showed significant differences before and after the fatigue protocol in the run-up speed (F=5.66 ; p=0.02), in the maximum speed of the forearm (F=5.85 ; p=0.02) and the hand (F=4.01 ; p=0.04), in the speed in the shoulder joint (F=5.39 ; p=0.02) and wrist joint (F=4.06 ; p=0.04), and in the ball shooting speed (F=5.42 ; p=0.02). The accuracy of the shot was, on average, lower (36.20 vs. 33.17 cm) but not significantly so.
