# Influence of Fatigue and Defensive Pressure on Three-Point Jump-Shot Kinematics in Basketball
## 3 Results

Table 2: Descriptive parameters of observed kinematic variables in different jump-shot conditions. When conducting the repeated-measures ANOVA, general statistically significant difference was determined (F = 13.43; \(p\) < 0.01). As differences were established in repeated-measures ANOVA, the Tukey post-hoc (Table 3) test was used to further analyze the interactions between the conditions. In the Jump_H variable, conditions 1, 2, and 3 presented significant differences in relation to condition 4 (_p_ = 0.03). The center of mass in the catching and shooting phases differed significantly between CON2 and both conditions after the fatigue protocol. Moreover, CON1 presented differences in relation to CON4 in these two variables. Maximum height release of non-fatigue conditions showed significant differences (_p_ < 0.01) in relation to CON4. The shoulder angle during ball release showed differences between CON2 and conditions after the fatigue protocol. In the Hor_D variable, significant differences were determined between non-fatigue and fatigue conditions (_p_ < 0.00 and 0.02). The duration of shot (Sh_T) did not differ only between CON1 and CON4. With other variables (Shoulder_V; Upper arm_V; Forearm_V; and Arc), statistics did not present any differences. \begin{table}

Table 3: The results of the Tukey post-hoc test. Figure 2 shows that participants performed highest shooting precision in CON4 and lowest in CON1. Additionally, the shooting precision was the same between CON2 and CON3.
