# Influence of Fatigue and Defensive Pressure on Three-Point Jump-Shot Kinematics in Basketball
## 3 Results  
The descriptive parameters of heart rate among conditions and the 300 m protocol are presented in Table 1. In the 300 m running test, the average result was 76.22 s. Heart rate during this test was at 187.07 beats per minute (BPM). In condition 1 (CON1_HR), which was shooting without influence of fatigue and defense, athletes had an average 148.81 BPM. CON2_HR showed similar values as CON1_HR. After the fatigue protocol, HR was 33-38 BPM higher. Considering that HR in the 300 m test was at 187 BPM, in CON4_HR the heart rate was nearly maximal. In Table 2, mean and standard deviation values were presented for each observed condition. The highest values of the jump height were determined in CON4 (16.44 cm). Furthermore, the height of the center of mass during ball catching was highest in CON4. The lowest point of the center of mass during the jump-shot performance was in CON1. The release height was highest in CON2. The shoulder angle was higher in the no-fatigue condition, whilst under the influence of defense it did not show differences. The slowest velocity of segments was determined in the upper arm during shooting in CON1 (1.13 m/s). In the horizontal displacement variable, the longest distance was covered in CON1(37.10 cm) and CON2 (36.99 cm). The shot time was quickest in the condition without fatigue and with a defensive player. In the same condition, the arc of the ball was the highest (45.35). \begin{table}
