Differences in some kinematic parameters during shooting for two and three points in basketball under influence of different physiological loads

The aim of this study was to determine whet her a progressive physiological load affects changes in certain kinematic parameters when performing a two and three-point jump shot in basketball. The effect of fatigue on jump height, duration of the flight phase, and duration of contact with the ground, amortization angle were observed through the concentric and eccentric contraction phases with respect to the duration of the shot, the shoulder angle and the angle at which the ball enters the basket. In this study, 6 participants were members of the Croatian national basketball team with an average age 16, 46 ± 0, 71 y, body height of 188.88 ± 5.09 cm, body mass of 80.71 ± 2.06 kg and subcutaneous fat tissue of 11.96 ± 2.14%. Descriptive indicators (Min, Max, Mean, Sd) were obtained and the anova for repeated measures showed statistically significant differences in jump height(F=10.16, p<0, 00), duration of the flight phase (F=9.53, p<0, 00), duration of contactwith the ground (F=15.20, p <0.00) and duration of the concentric contraction phase(F=20.91, p<0.00)under the influence of progressive physiological load for two-points shots. And in the three-points shot the difference in jump height (F=9.09, p<0, 00), duration of the flight phase (F=10.29, p<0, 00), duration of contactwith the ground (F=15.20, p <0.00) and duration of the concentric contraction phase(F=11.65, p<0.00) and finally with the duration of the eccentric contraction(F=5.96, p<0.02). Analysing kinematic parameters when performing a two and three-point jump shot under the influence of progr essive physiological load we can conclude that certain kinematic parameters changed because of fatigue such as: jump height, duration of the flight phase, duration of contact with the ground and duration of concentric and eccentric contraction phases. Future studies should concentrate on different player positions under the influence of progressive physiological load.
