The aims of this study were twofold: (1) to characterize repeated high-intensity movement activity profiles of a professional soccer team in official match-play; and (2) to inform and verify the construct validity of tests commonly used to determine repeated-sprint ability in soccer by investigating the relationship between the results from a test of repeated-sprint ability and repeated high-intensity performance in competition. High-intensity running performance (movement at velocities >19.8 km · h(-1) for a minimum of 1 s duration) was measured in 20 players using computerized time-motion analysis. Performance in 80 French League 1 matches was analysed. In addition, 12 of the 20 players performed a repeated-sprint test on a non-motorized treadmill consisting of six consecutive 6 s sprints separated by 20 s passive recovery intervals. In all players, most consecutive high-intensity actions in competition were performed after recovery durations ≥61 s, recovery activity separating these efforts was generally active in nature with the major part of this spent walking, and players performed 1.1 ± 1.1 repeated high-intensity bouts (a minimum of three consecutive high-intensity bouts with a mean recovery time ≤20 s separating efforts) per game. Players reporting lowest performance decrements in the repeated-sprint ability test performed more high-intensity actions interspersed by short recovery times (≤20 s, P < 0.01 and ≤30 s, P < 0.05) compared with those with higher decrements. Across positional roles, central-midfielders performed more high-intensity actions separated by short recovery times (≤20 s) and spent a larger proportion of time running at higher intensities during recovery periods, while fullbacks performed the most repeated high-intensity bouts (statistical differences across positional roles from P < 0.05 to P < 0.001). These findings have implications for repeated high-intensity testing and physical conditioning regimens.
(1) 描述职业足球队在正式比赛中的高强度重复运动活动模式；(2) 通过研究重复冲刺能力测试结果与比赛中高强度重复表现之间的关系，为常用于确定足球重复冲刺能力的测试提供信息并验证其结构有效性。使用计算机时间-运动分析，对 20 名球员的高强度跑动表现（速度>19.8km·h(-1)且持续至少 1s 的运动）进行了测量。分析了 80 场法国甲级联赛比赛中的表现。此外，20 名球员中的 12 名在非电动跑步机上进行了重复冲刺测试，该测试由六个连续的 6s 冲刺组成，间隔 20s 的被动恢复间隔。在所有球员中，比赛中大多数连续的高强度动作都是在恢复时间≥61s 后进行的，恢复活动通常是积极的，大部分是步行，球员每场比赛进行 1.1±1.1 次高强度重复（至少有三次连续高强度动作，平均恢复时间≤20s 分隔努力）。在重复冲刺能力测试中报告最低性能下降的球员在较短的恢复时间（≤20s，P<0.01 和≤30s，P<0.05）之间进行了更多的高强度动作，与那些性能下降较大的球员相比。在各个位置角色中，中场球员在较短的恢复时间（≤20s）之间进行了更多的高强度动作，在恢复期间花费更多的时间以较高的强度奔跑，而边后卫则进行了最多的高强度重复动作（不同位置角色之间的统计差异从 P<0.05 到 P<0.001）。这些发现对高强度重复测试和身体适应方案具有影响。
