The ability to differentiate the elite from nonelite athletes is not clearly defined. We investigated level differences in speed, change of direction speed (CODS), and reactive agility in a group of trained adolescent soccer players. A total of 75 adolescent male soccer players (aged 14-19 years) were recruited. The players were grouped based on the level of play to elite, sub-elite, and amateur players. Players were tested for 5-, 10- and 20-m sprints, CODS, and reactive agility tests (RAT). Elite players had faster reaction movement time during RAT with live opponent stimuli ( ≤ 0.01) compared to sub-elite and amateur players. Moreover, elite players showed a faster time during light stimuli ( ≤ 0.01) but only compared to amateur players. The times for 5-m and 10-m sprint groups did not differ ( > 0.05). The results demonstrated that the skilled players (elite and sub-elite) performed better in reactive agility tests, speed, and COD speed compared to amateur players. Additionally, we can conclude that total and reaction time in the agility test with live opponent stimuli can be a significant factor that differentiates between adolescent soccer players considering their level.
区分精英运动员和非精英运动员的能力尚未明确界定。我们研究了一组训练有素的青少年足球运动员在速度、变向速度（CODS）和反应敏捷性方面的水平差异。共有 75 名青少年男性足球运动员（年龄 14-19 岁）被招募。根据比赛水平，球员被分为精英、次精英和业余球员。对球员进行 5 米、10 米和 20 米短跑、CODS 和反应敏捷性测试（RAT）。与次精英和业余球员相比，精英球员在有实际对手刺激的 RAT 中具有更快的反应运动时间（≤0.01）。此外，与业余球员相比，精英球员在轻刺激下的时间更快（≤0.01）。5 米和 10 米短跑组的时间没有差异（>0.05）。结果表明，与业余球员相比，技术娴熟的球员（精英和次精英）在反应敏捷性测试、速度和变向速度方面表现更好。此外，我们可以得出结论，考虑到青少年足球运动员的水平，带有实际对手刺激的敏捷测试中的总时间和反应时间可以是区分他们的重要因素。
