Los Arcos, A and Martins, J. Physical fitness performance of young professional soccer players does not change during several training seasons in a Spanish elite reserve team: club study, 1996-2013. J Strength Cond Res 32(9): 2577-2583, 2018-The purpose of this study was to assess the changes in physical fitness performance in young professional soccer players during several training seasons in a Spanish elite reserve team. Physical test values (i.e., vertical jump test, straight line sprint test, and discontinuous and progressive submaximal running test) of 97 young professional soccer players who belonged for at least 2 consecutive seasons to the reserve team of a Spanish professional team from 1996 to 2013 were analyzed. A distinction was made between the soccer players who were promoted to the Spanish first/second divisions (n = 38) and those who were not (n = 59) (until the end of the 2016/2017 season). Players were also classified according to their playing positions. Independently of the competitive level reached and the playing position, the variability of the fitness performance was limited (coefficient of variation <6%) and the players did not improve their fitness values (effect size ≤ small) from the first to the last season in which they were enrolled in the team (after 2-4 seasons). During the last stage of training in an elite soccer academy, young professional soccer players achieve a very similar physical fitness performance when their soccer competence is evaluated, and other soccer performance factors are those which make them stand out for selection.
洛斯阿科斯和马蒂内斯，J. 西班牙精英预备队中，年轻职业足球运动员的身体素质表现不会在几个训练赛季中发生变化：俱乐部研究，1996-2013 年。J 力量与条件研究 32(9)：2577-2583，2018 年-本研究的目的是评估西班牙精英预备队中年轻职业足球运动员在几个训练赛季中身体素质表现的变化。分析了 1996 年至 2013 年期间至少连续两个赛季属于西班牙职业队预备队的 97 名年轻职业足球运动员的体能测试值（即垂直跳跃测试、直线冲刺测试和不连续和渐进式亚最大跑步测试）。根据他们晋升到西班牙第一/第二分区的足球运动员（n = 38）和那些没有晋升的足球运动员（n = 59）（到 2016/2017 赛季结束）进行了区分。根据他们的比赛位置，球员也进行了分类。无论达到的竞争水平和比赛位置如何，体能表现的可变性都很有限（变异系数<6%），并且球员从参加球队的第一个赛季到最后一个赛季（在 2-4 个赛季后）都没有提高他们的体能值（效果大小≤小）。在精英足球学院的最后训练阶段，当评估他们的足球能力时，年轻的职业足球运动员会达到非常相似的身体素质表现，而其他足球表现因素则是使他们脱颖而出的因素。
