Abstract

ABSTRACT Talent identification and selection process in young football is based on coaches’ decisions regarding the players’ performance at early ages. The aim of this study was to show how the maturity status and the relative age impact on young football players’ physical performance and their coaches’ efficacy expectations. The physical performance (1RM, Peak power output [PPO], 30-m sprint and t-test) of 118 young football players (U13 to U15; and their coaches’ efficacy expectations were assessed. Relative age was calculated according to the players’ date of birth within their selection year. The maturity status was estimated as the years from/to their peak height velocity (PHV). Linear regression analyses showed a significant relationship between players’ physical performance and their maturity status but not with their relative age. In contrast, the maturity status of players only was associated to the coaches’ efficacy expectations in the 1RM and PPO tests, whereas the relative age was a predictor of the coaches’ expectations about players’ performance in the t-test. These findings may be important for coaches and managers in young football academies since inter-individual differences in the maturity status but not in the relative age are related to physical performance despite the coaches’ expectations.
成熟度而非相对年龄对优秀青年足球运动员身体素质的影响
摘要:年轻足球的人才识别和选拔过程是基于教练对球员早期表现的决定。本研究的目的是展示成熟度和相对年龄如何影响年轻足球运动员的身体表现和教练的效能预期。对118名U13至U15年轻足球运动员的身体表现(1RM、峰值功率输出[PPO]、30米短跑和t检验)及其教练的疗效预期进行了评估。根据球员在其选择年份内的出生日期计算相对年龄。成熟状态估计为从/到其峰值身高速度(PHV)的年份。线性回归分析显示,球员的身体表现与他们的成熟状态之间存在显著关系,但与他们的相对年龄无关。相反,在1RM和PPO测试中,球员的成熟度仅与教练的效能预期相关,而在t检验中,相对年龄是教练对球员表现预期的预测因素。这些发现对年轻足球学院的教练和管理者来说可能很重要,因为尽管教练有期望,但成熟状态而非相对年龄的个体间差异与身体表现有关。
