Purpose: The aim of this study was 2-fold: (1) to assess and compare the external and internal load of elite young soccer players during competitive microcycles and (2) to describe the training/match ratios (TMr) in elite male youth soccer players. Method: Twenty-one youth soccer players were monitored using a 10-Hz global positioning system. Total distance covered, running distance (RD), high-speed RD, sprint distance, number of accelerations and decelerations, player load, and rated perceived exertion were recorded during training sessions and matches. The TMr was calculated for each load measure. All variables were also normalized dividing the load per minute of activity. Results: The RD, high-speed running, and sprint distance were higher 3 days before the match and 2 days before match compared with the rest of the training sessions. However, accelerations, decelerations, and player load were higher 4 days before match than other sessions. Besides this, the TMr of RD, high-speed running, and sprint distance were associated with lower values than the TMr of total distance covered, accelerations, decelerations, and player load. The match constituted the highest load during competitive microcycle. Conclusions: The present data support the idea that youth soccer coaches and practitioners must consider relative training load according to match demands to better manage and evaluate player periodization.

目的：本研究的目的有两个：（1）评估和比较精英青年足球运动员在竞技微循环期间的外部和内部负荷；（2）描述精英男青年的训练/比赛比率（TMr）足球运动员。方法：使用 10-Hz 全球定位系统监测 21 名青年足球运动员。在训练课程和比赛期间记录了总跑距离、跑步距离 (RD)、高速 RD、冲刺距离、加速和减速次数、球员负荷和额定感知用力。为每个负载测量计算 TMR。所有变量也被归一化，除以每分钟活动的负荷。结果：与其他训练课程相比，赛前 3 天和赛前 2 天的 RD、高速跑和冲刺距离更高。然而，赛前 4 天的加速、减速和球员负荷高于其他时段。除此之外，RD、高速跑步和冲刺距离的 TMr 与总覆盖距离、加速度、减速度和运动员负荷的 TMr 值相关。比赛构成了竞技微循环中的最高负荷。结论：目前的数据支持这样的观点，即青年足球教练和从业者必须根据比赛需求考虑相对训练负荷，以更好地管理和评估球员的分期。
