The aim of this study was to compare the distances at various intensity in matches and small-sided games in elite-young soccer players using the metabolic power approach and running speed methods through fixed and individual speed zones. The second aim was to investigate the difference in high intensity external workload (% of total distances covered > 16 km/h or > 20 W/kg) between matches and small-sided games. Global positioning system data from 14 elite-youth players were analyzed during 13 matches and two types of small sided-games. Five intensity zones were used to compare the running distances between the metabolic power approach and the classic performance analysis. Metabolic power recorded more distances covered at high intensity than the running speed methods for every playing situations, except for the zone 5 of fixed speed (> 19 km/h) in matches (P<0.05). Smaller differences of external workload at high intensity were found when using the metabolic power approach compared to the traditional performance analysis. Our results highlight that the traditional analysis underestimates the athlete's high intensity efforts. The metabolic power approach seems more relevant to monitor matches and training situations but also to compare matches to small-sided games in elite-young soccer players.
本研究旨在通过固定和个体速度区间，使用代谢功率法和跑动速度法比较精英年轻足球运动员在比赛和小场比赛中不同强度下的跑动距离。第二个目的是研究比赛和小场比赛之间高强度外部工作量（%总跑动距离>16km/h 或>20W/kg）的差异。对 14 名精英青年球员在 13 场比赛和两种类型的小场比赛中的全球定位系统数据进行了分析。使用五个强度区间比较了代谢功率法和经典表现分析之间的跑动距离。在所有比赛情况下，除了比赛中的固定速度区 5（>19km/h）外，代谢功率法记录的高强度跑动距离都比跑动速度法多（P<0.05）。与传统表现分析相比，使用代谢功率法时高强度外部工作量的差异较小。我们的结果表明，传统分析低估了运动员的高强度努力。代谢功率法似乎更能监测比赛和训练情况，也更能将比赛与精英年轻足球运动员的小场比赛进行比较。
