Mireille, M, Johan, P, Matthieu, L, and Pieter, V. A retrospective analysis of the national youth teams in volleyball: Were they always faster, taller, and stronger? J Strength Cond Res 36(9): 2615-2621, 2022-Although there are numerous studies comparing the characteristics of young and adult volleyball players of different levels, it remains unclear to what extent these findings can be used for performance prediction because very few are based on longitudinal or retrospective analyses. The aim of the current retrospective study was to test to what extent anthropometry, physical performance, and motor coordination can predict future selection in national youth teams. From 2012 to 2015, 1738 10- to 13-year-old boys and girls who played volleyball completed 3 anthropometric, 4 physical performance, and 3 motor coordination tests. In January 2020, 52 athletes of this sample were found to be part of one of the national youth teams of Belgium. A multivariate analysis of covariance, discriminant analyses, and logistic regression analyses were conducted to compare the test results of the selected vs. the nonselected players. Significance level was set at p ≤ 0.05. Results showed that the selected players were already taller and showed better jumping performance, and for females, they tended to have better motor coordination at the time of baseline measurement. Therefore, it seems important to focus on the development of motor coordination and jumping performance at young ages because superiority in these characteristics increases the chances to be selected for the national team 4-8 years later. Nevertheless, considering the large variation in results, selection cannot be made based on these characteristics alone. The practical implications for coaches and federations with respect to training and talent detection are discussed.
米雷耶、M、约翰、P、马修、L 和皮特、V. 一项关于国家青年排球队的回顾性分析：他们是否总是更快、更高、更强壮？J 力量与体能研究 36(9)：2615-2621，2022-虽然有许多研究比较了不同水平的年轻和成年排球运动员的特点，但由于很少有研究基于纵向或回顾性分析，因此仍不清楚这些发现在多大程度上可以用于预测表现。本回顾性研究的目的是测试人体测量学、身体表现和运动协调能力在多大程度上可以预测未来在国家青年队中的选拔。从 2012 年到 2015 年，1738 名 10-13 岁的男孩和女孩参加了 3 项人体测量学、4 项身体表现和 3 项运动协调测试。2020 年 1 月，发现该样本中的 52 名运动员是比利时国家青年队的一员。进行了多元协方差分析、判别分析和逻辑回归分析，以比较入选和未入选运动员的测试结果。显著性水平设为 p ≤ 0.05。结果表明，入选运动员的身高更高，跳跃表现更好，而对于女性，她们在基线测量时的运动协调能力往往更好。因此，似乎重要的是要在年轻时关注运动协调和跳跃表现的发展，因为这些特征的优势会增加 4-8 年后入选国家队的机会。然而，考虑到结果的巨大差异，不能仅根据这些特征进行选拔。讨论了教练和联合会在训练和人才选拔方面的实际意义。
