The present study examined whether performance characteristics discriminated between selected and deselected players in talent development programmes. This examination was carried out in talented soccer players, aged 16-18 years using objective measurement instruments. Four domains of multidimensional performance characteristics (physiological, technical, tactical and psychological) were assessed by using a test battery consisting of soccer-specific field tests and questionnaires. Multivariate analyses of covariance revealed that the physiological characteristics peak and repeated shuttle sprint, the technical characteristics of peak and repeated shuttle dribble and the tactical characteristic of 'positioning and deciding', significantly differed between the selected (n=76) and deselected players (n=37), with selected players performing better (P<0.05). Discriminant function analysis showed that the combination of the technical characteristic 'peak dribbling', the tactical characteristic 'positioning and deciding' and the physiological characteristic of 'peak sprinting' classified 69% of talented players correctly. In conclusion, the decisions made by the investigated clubs to either select or deselect players in their talent development programme, whom were aged 16-18 years, were mostly discriminated by aspects of the players' technical, tactical and physiological skill performances. Sports research can play an essential role in investigating the club's perception of important performance characteristics in talented players.
本研究旨在探讨在青少年足球人才发展计划中，表现特征是否可以区分入选和落选的球员。本研究通过使用客观的测量工具，对 16-18 岁的有天赋的足球运动员进行了研究。通过使用由足球专项场测试和问卷组成的测试组合，评估了多维表现特征的四个领域（生理、技术、战术和心理）。协方差的多变量分析显示，在生理特征中的峰值和重复穿梭冲刺、技术特征中的峰值和重复穿梭运球，以及战术特征中的“定位和决策”方面，入选球员（n=76）和落选球员（n=37）之间存在显著差异，入选球员表现更好（P<0.05）。判别函数分析表明，技术特征“峰值运球”、战术特征“定位和决策”以及生理特征“峰值冲刺”的组合可以正确分类 69%的有天赋的球员。总之，在所研究的俱乐部在其青少年足球人才发展计划中做出的入选或落选球员的决定，主要是通过球员的技术、战术和生理技能表现的各个方面来区分的。体育研究可以在调查俱乐部对有天赋的球员的重要表现特征的看法方面发挥重要作用。
