This study aimed to report possible anthropometrical and physical performance differences between youth soccer players with different maturity status and to report the coaches' expectations, hypothesizing that coaches would expect more from players with advanced maturity. One hundred twenty-two (122) players completed a physical performance battery. Their maturity status was estimated and the coaches' efficacy expectations (CEEs) were assessed. Players with advanced maturation had better physical performance (F = 26.5-73.4; p < 0.01) and their CEEs for strength-related tasks were different according to the maturity status (F = 8.3-10.9; p < 0.01), but not for speed-related tests, nor for their general ability to play soccer. Normalized data showed significant differences between physical performance tests and their respective CEEs within each maturity group, especially in the Post-PHV group. This study confirms the physical advantages of players with advanced maturity while it shows controversial results of how maturation affects the coaches' perceptions and, indirectly, the coaches' identification and selection of talented players.
本研究旨在报告不同成熟状态的青少年足球运动员之间可能存在的人体测量学和身体表现差异，并报告教练的期望，假设教练对成熟度较高的球员期望更高。122名球员完成了一系列身体表现测试。评估了他们的成熟状态，并评估了教练的效能期望（CEEs）。成熟度较高的球员身体表现更好（F = 26.5 - 73.4；p < 0.01），并且他们在与力量相关任务上的CEEs根据成熟状态有所不同（F = 8.3 - 10.9；p < 0.01），但在与速度相关的测试以及他们踢足球的总体能力方面并非如此。标准化数据显示，在每个成熟度组内，身体表现测试与其各自的CEEs之间存在显著差异，尤其是在青春期后期高峰（Post - PHV）组。本研究证实了成熟度较高的球员在身体方面的优势，同时显示出关于成熟度如何影响教练的认知，以及间接影响教练对有天赋球员的识别和选拔的有争议的结果。
