'Practise makes perfect' is a well-known expression in most sports, including top-level soccer. However, a high training and match load increases the risk for injury, overtraining and burnout. With the use of accelerometers and a self-report questionnaire, the aim of this study was to describe talented players' physical activity (PA) level. Data were collected three times during the 2011 Norwegian Football season (March, June and October). The accelerometer output, counts·min(-1) (counts per unit time registered), reports the daily PA-level for young talented soccer players. Results showed a stable PA-level across the season (March: 901.2 counts·min(-1), June: 854.9 counts·min(-1), October: 861.5 counts·min(-1)). Furthermore, comparison of five different training sessions across the season showed that the PA-level ranged from 2435.8 to 3745.4 counts·min(-1). A one-way ANOVA showed no significant differences between the three measured weeks during the soccer season (p≤0.814). However, the training sessions in January had a significantly higher PA-level than those in June and October (p≤0.001). Based on these results, we discuss how potential implications of PA-level affect factors such as risk of injury, overtraining and burnout. We argue that player development must be seen as part of an overall picture in which club training and match load should be regarded as one of many variables influencing players' PA-level. Key pointsIt is well established that to achieve a high performance level in sport, one must implement a high training and match load in childhood and youth.With the use of accelerometers and a self-reported questionnaire, the aim of this study was to describe talented players' total physical activity (PA) load.These results indicate that young talented soccer players must overcome large doses of PA on a weekly basis, exposing them to a high risk of injury, overtraining and burnout.
“熟能生巧”是大多数运动中众所周知的说法，包括顶级足球。然而，高训练和比赛负荷会增加受伤、过度训练和倦怠的风险。本研究使用加速度计和自我报告问卷，旨在描述有天赋的球员的身体活动（PA）水平。数据在 2011 年挪威足球赛季期间分三次收集（3 月、6 月和 10 月）。加速度计的输出，以计数·分钟（-1）（单位时间内记录的计数）表示，报告年轻有天赋的足球运动员的日常 PA 水平。结果显示，整个赛季的 PA 水平保持稳定（3 月：901.2 计数·分钟（-1），6 月：854.9 计数·分钟（-1），10 月：861.5 计数·分钟（-1））。此外，对整个赛季五个不同训练课程的比较显示，PA 水平在 2435.8 到 3745.4 计数·分钟（-1）之间。单向方差分析显示，足球赛季中三个测量周之间没有显著差异（p≤0.814）。然而，1 月的训练课程的 PA 水平明显高于 6 月和 10 月（p≤0.001）。基于这些结果，我们讨论了 PA 水平对受伤、过度训练和倦怠等因素的潜在影响。我们认为，球员的发展必须被视为一个整体画面的一部分，其中俱乐部的训练和比赛负荷应被视为影响球员 PA 水平的众多变量之一。要点在体育运动中，要达到高水平的表现，必须在儿童和青年时期实施高训练和比赛负荷。本研究使用加速度计和自我报告问卷，旨在描述有天赋的球员的总身体活动（PA）负荷。这些结果表明，年轻有天赋的足球运动员必须每周克服大量的 PA，使他们面临受伤、过度训练和倦怠的高风险。
