Kinematic analysis is an objective method for examining basketball technique. However, there are just a few studies featuring a kinematic analysis of passing. The purpose of this study was to determine whether the kinematic parameters and accuracy of passing changed when players were under the influence of fatigue. Eleven Croatian basketball players who are members of the youth national program (age: 18.36 ± 0.67 years; height: 192.32 ± 9.98 cm; weight: 83.35 ± 11.19 kg; body fat: 15.00 ± 4.40%, arm span: 194.34 ± 10.39 cm) participated in fatigue and non-fatigue repetitive tests. A Xsens suit was used to analyze the kinematic parameters of push passing; a radar gun was used to determine ball speed; heart rate and blood lactate were used to identify fatigue and non-fatigue state. There was a significant difference in angular velocities of shoulder ( = 0.01), elbow ( = 0.04), and wrist ( = 0.01), accuracy ( = 0.01), ball speed ( = 0.00), pelvis position ( = 0.00), and velocity of the pelvis in X-axis ( = 0.00) between fatigue and non-fatigue state. Fatigue influences some kinematic parameters and accuracy of passing. The findings of this study suggest that coaches conduct as many drills as possible in situational conditions that are similar to the conditions during the basketball game itself.
运动学分析是一种检查篮球技术的客观方法。然而，仅有少数研究对传球进行了运动学分析。本研究的目的是确定当球员疲劳时，传球的运动学参数和准确性是否会发生变化。11 名来自青年国家队的克罗地亚篮球运动员（年龄：18.36±0.67 岁；身高：192.32±9.98cm；体重：83.35±11.19kg；体脂：15.00±4.40%，臂展：194.34±10.39cm）参加了疲劳和非疲劳重复测试。使用 Xsens 套装分析推传球的运动学参数；使用雷达枪确定球速；心率和血乳酸用于确定疲劳和非疲劳状态。在肩角速度（=0.01）、肘角速度（=0.04）和腕角速度（=0.01）、准确性（=0.01）、球速（=0.00）、骨盆位置（=0.00）和骨盆在 X 轴上的速度（=0.00）方面，疲劳和非疲劳状态之间存在显著差异。疲劳会影响传球的一些运动学参数和准确性。本研究的结果表明，教练应尽可能在类似于篮球比赛本身的情况下进行现场条件的训练。
