To compare anthropometric and power-related attributes between competition levels in under-19-year-old (U19) male basketball players.
National-level (n = 7; age: 17.7 [0.5] y), first-division state-level (n = 8; 17.4 [0.4] y), and second-division state-level (n = 8; 17.1 [0.4] y) players from Australian basketball programs participated in this pilot study. Players had various anthropometric attributes (height, standing reach height, wingspan, and body mass) and power-related attributes (isometric midthigh pull, linear sprint, countermovement jump, 1-step vertical jump, standing long jump, repeated lateral bound, and Modified Agility T Test) measured in the preseason. Differences between groups were assessed using 1-way analyses of variance with Tukey post hoc tests and effect sizes (ES) interpreted as trivial, <0.20; small, 0.20 to 0.59; moderate, 0.60 to 1.19; large, 1.20 to 1.99; and very large, ≥2.00.
Regarding anthropometric attributes, national-level players possessed greater (P < .05, large-very large) height (ES = 2.09), standing reach height (ES = 1.54), wingspan (ES = 1.45), and body mass (ES = 1.77) than second-division state-level players. For power-related attributes, national-level players possessed greater (P < .05, large-very large) isometric midthigh-pull peak force (ES = 1.46-2.57), sprint momentum (ES = 1.17-2.18), and countermovement jump peak force (ES = 1.73-2.01) than state-level players. Moreover, national-level players demonstrated greater (P < .05) 1-step vertical jump height (ES = 1.95, large) than second division state-level players.
Specific anthropometric and power-related attributes clearly differ between competition levels in U19 male basketball players. This information can inform development of testing protocols, reference ranges, and training programs in practice. Further research is encouraged on this topic to confirm our findings across larger samples of basketball players.
比较19岁以下（U19）男性篮球运动员不同竞赛水平之间的人体测量学和力量相关属性。
来自澳大利亚篮球项目的国家级（n = 7；年龄：17.7 [0.5]岁）、一级州级（n = 8；17.4 [0.4]岁）和二级州级（n = 8；17.1 [0.4]岁）球员参与了这项初步研究。球员们在季前赛中测量了各种人体测量学属性（身高、站立摸高、臂展和体重）以及力量相关属性（等长股四头肌拉力、直线冲刺、反向纵跳、单步垂直跳、立定跳远、重复侧向跳跃和改良敏捷T测试）。使用单因素方差分析和Tukey事后检验评估组间差异，并将效应量（ES）解释为微不足道，<0.20；小，0.20至0.59；中等，0.60至1.19；大，1.20至1.99；非常大，≥2.00。
在人体测量学属性方面，国家级球员的身高（ES = 2.09）、站立摸高（ES = 1.54）、臂展（ES = 1.45）和体重（ES = 1.77）比二级州级球员更大（P < .05，大至非常大）。在力量相关属性方面，国家级球员的等长股四头肌拉力峰值力（ES = 1.46 - 2.57）、冲刺动量（ES = 1.17 - 2.18）和反向纵跳峰值力（ES = 1.73 - 2.01）比州级球员更大（P < .05，大至非常大）。此外，国家级球员的单步垂直跳高度（ES = 1.95，大）比二级州级球员更高（P < .05）。
U19男性篮球运动员不同竞赛水平之间的特定人体测量学和力量相关属性存在明显差异。这些信息可为实际中的测试方案、参考范围和训练计划的制定提供参考。鼓励就该主题进行进一步研究，以在更大样本的篮球运动员中证实我们的发现。
