Talent development programmes for professional soccer clubs aim to guide players towards professional level performance. We identify whether the intermittent endurance capacity of these players may have changed over time. Since the 2000/2001 competition season, the intermittent endurance capacity of players in the talent development programmes of two professional soccer clubs was measured annually. A total of 492 players participated, divided across seven age categories (under 13 (U13), U14, U15, U16, U17, U18, U19) and resulting in 953 measurements. Analyses of variance showed an improvement in intermittent endurance capacity from the 2000/2001 season to 2009/2010 of around 50% in all age groups (P < 0.05). A possible explanation is the increased quantity and quality of training over the years. When identifying, developing and selecting young players, scouts, trainers and coaches have to be aware that the current level of soccer and its underlying performance characteristics--such as intermittent endurance capacity--are improving over time. This factor may have consequences for current young players aiming to make it to the top 10 years from now.
人才发展计划旨在引导球员达到专业水平的表现。我们确定这些球员的间歇性耐力能力是否随时间发生了变化。自 2000/2001 赛季以来，我们每年都会对两家职业足球俱乐部的人才发展计划中的球员的间歇性耐力能力进行测量。共有 492 名球员参加，分为七个年龄组（U13、U14、U15、U16、U17、U18、U19），共进行了 953 次测量。方差分析显示，所有年龄组的间歇性耐力能力从 2000/2001 赛季到 2009/2010 赛季都有所提高，大约提高了 50%（P<0.05）。一个可能的解释是，多年来训练的数量和质量都有所增加。在识别、培养和选拔年轻球员时，球探、教练和教练必须意识到，当前的足球水平及其潜在的表现特征（如间歇性耐力能力）正在随着时间的推移而提高。对于目前的年轻球员来说，这一因素可能会对他们在未来 10 年内进入顶级联赛产生影响。
