The purpose of the study was to (1) assess the training load experienced during pre-season and in-season meso-cycles within youth academy soccer players and (2) investigate the extent to which the intended periodized approach was implemented, considering those factors that affected its realization. An explanatory sequential mixed-method design comprising two phases was adopted. Phase 1 encompassed the quantitative analysis of training load data, using 10 Hz GPS, and consisted of 17 youth academy soccer players (age 17 ± 1 yrs; stature 179 ± 9 cm; body mass 72 ± 9 kg), from a professional English soccer academy. Phase 2 involved the collection of qualitative data in relation to the data collected in phase 1 of the study. Three semi-structured interviews were conducted with the lead strength and conditioning coach at the same academy, to gain his reflections on the data, its alignments with desired outcomes, and factors that impacted on the enactment of the periodized training programme. The results provide original information on the training load experienced within a youth soccer academy and novel insights into the complex realities of enacting periodized training programmes in practice.
(1)评估青年学院足球运动员在赛季前和赛季中中周期经历的训练负荷；(2)考虑到影响其实现的因素，调查实施预期的周期性方法的程度。采用了包含两个阶段的解释性顺序混合方法设计。第 1 阶段包括使用 10 Hz GPS 对训练负荷数据的定量分析，涉及来自一家专业英国足球学院的 17 名青年学院足球运动员（年龄 17 ± 1 岁；身高 179 ± 9 厘米；体重 72 ± 9 公斤）。第 2 阶段涉及与研究第 1 阶段收集的数据相关的定性数据的收集。与同一学院的首席力量和调理教练进行了三次半结构化访谈，以了解他对数据的看法、数据与预期结果的一致性以及影响周期性训练计划实施的因素。研究结果提供了有关青年足球学院内部经历的训练负荷的原始信息，并深入了解了在实践中实施周期性训练计划的复杂现实。
