The aim of this study was to determine whether declines in physical performance in a professional soccer team during match-play were associated with reductions in skill-related performance. Computerized tracking of performance in midfield players (n = 11) showed that total distance and distance covered in high-speed running (>14.4 km · h⁻¹) were greater in the first versus second half of games (both P < 0.001) and in the first versus the final 15 min of play (P < 0.05). Analysis of high-speed running across 5-min periods showed that more distance was covered in the first versus the final game period, and in the peak period of activity compared with the following period and game mean for other periods (all P < 0.05). Analysis of skill-related measures revealed no significant decline between halves, across 15-min intervals or in the 5-min period following that of peak high-speed activity compared with the game mean for other 5-min periods. In contrast, frequencies of passing, ball possessions, and duels were greater in the first 5-min than in the final 5-min period (P < 0.05). Neither physical nor skill-related performance was affected across three consecutive games within a period of ≤7 days. The results suggest that the players were generally able to maintain skill-related performance throughout games and when competing in successive matches within a short time.
本研究旨在确定职业足球运动员在比赛中体能表现的下降是否与技能表现的下降有关。对中场球员（n = 11）表现的计算机跟踪显示，总距离和高速跑动（> 14.4 公里/小时）距离在比赛的上半场与下半场（均 P < 0.001）和上半场与最后 15 分钟的比赛（P < 0.05）之间更大。对 5 分钟期间高速跑动的分析表明，与最后一个比赛阶段相比，与下一个比赛阶段相比，第一个比赛阶段覆盖的距离更远，与其他阶段的比赛平均相比，活动高峰期的距离更远（均 P < 0.05）。对技能相关措施的分析表明，与其他 5 分钟阶段的比赛平均值相比，在比赛的两个半场之间、在 15 分钟的间隔内或在高峰高速活动后的 5 分钟内，并没有明显的下降。相比之下，在第一个 5 分钟内，传球频率、控球次数和决斗次数都大于最后一个 5 分钟（P < 0.05）。在不超过 7 天的时间内，连续三场比赛中，无论是体能还是技能相关表现都没有受到影响。研究结果表明，球员在整个比赛中通常能够保持技能相关的表现，并且在短时间内连续比赛时也能保持这种表现。
