In this study, the effects of a prolonged period of fixture congestion (8 successive official matches in 26 days) on physical performance and injury risk and severity in a professional soccer team were investigated. Computerised motion-analysis was used to analyse the overall distance covered and that run at light- (0.0-11.0 km·h - 1); low- (11.1-14.0 km·h - 1); moderate- (14.1-19.7 km·h - 1) and high-intensities (≥19.8 km·h - 1) for the team as a whole. Distances were measured in metres per minute. Information on match injuries was recorded prospectively. The overall distance covered varied across successive matches (p<0.001) as more distance was run in games 4 and 7 compared to 2 and 3, respectively (126.6 ± 12.3 m·min - 1 and 125.0 ± 13.2 m·min - 1 vs. 116.0 ± 8.0 m·min - 1 and 115.5 ± 11.0 m·min - 1). Distance run in light-intensity exercise also varied (p<0.001) as more distance was covered in game 4 vs. 1, 2, 3, 5 and 6 (75.5 ± 3.8 m·min - 1 vs. 70.6 ± 2.4 m·min - 1, 71.8 ± 3.4 m·min - 1, 69.3 ± 2.6 m·min - 1, 71.5 ± 3.1 m·min - 1, and 70.3 ± 2.8 m·min - 1) and in game 8 vs. game 3 (73.1 ± 3.8 vs. 69.3 ± 2.6 m·min - 1), respectively. When comparing match halves, there were no differences across games in overall or high-intensity distance covered and performance in these measures was similar for matches played before, during and after this period. Globally, no difference over the 8 games combined was observed between the reference team and opponents in any of the performance measures whereas the overall distance covered and that in low- (both p<0.001) and high-intensity running (p=0.040) differed in individual games. The incidence of match injury during the congested fixture period was similar to rates reported outside this period but the mean lay-off duration of injuries was substantially shorter during the former (p<0.05). In summary, while the overall distance run and that covered at lower intensities varied across games, high-intensity running performance and injury risk were generally unaffected during a prolonged period of fixture congestion. These results might be linked to squad rotation and post-match recovery strategies in place at the present club.
在这项研究中，研究了在 26 天内连续进行 8 场正式比赛的情况下，对职业足球队的身体表现和受伤风险及严重程度的影响。使用计算机运动分析来分析整个距离和在低强度（0.0-11.0km·h-1）；中低强度（11.1-14.0km·h-1）；中高强度（14.1-19.7km·h-1）和高强度（≥19.8km·h-1）下的整体跑动距离。距离以米/分钟为单位进行测量。前瞻性地记录比赛受伤信息。连续比赛中覆盖的总距离不同（p<0.001），与第 2 和第 3 场比赛相比，第 4 和第 7 场比赛中跑动的距离分别增加（126.6±12.3m·min-1和 125.0±13.2m·min-1 vs. 116.0±8.0m·min-1和 115.5±11.0m·min-1）。轻强度运动中的跑动距离也有所不同（p<0.001），与第 1、2、3、5 和 6 场比赛相比，第 4 场比赛中覆盖的距离分别增加（75.5±3.8m·min-1 vs. 70.6±2.4m·min-1，71.8±3.4m·min-1，69.3±2.6m·min-1，71.5±3.1m·min-1，70.3±2.8m·min-1），与第 3 场比赛相比，第 8 场比赛中覆盖的距离分别增加（73.1±3.8 vs. 69.3±2.6m·min-1）。在比较比赛半场时，在总距离或高强度距离以及这些指标的表现方面，各场比赛之间没有差异，在这段时间前后进行的比赛表现相似。总体而言，在 8 场比赛的总和中，参考队和对手在任何表现指标上都没有差异，但在个别比赛中，总跑动距离和低强度（均 p<0.001）和高强度跑步（p=0.040）有差异。在比赛密集期间受伤的发生率与报告的该期间以外的发生率相似，但在前一时期受伤的平均休战时间要短得多（p<0.05）。总之，虽然总跑动距离和低强度跑动距离在比赛中有所不同，但高强度跑动的表现和受伤风险在长时间的比赛密集期间通常不受影响。这些结果可能与目前俱乐部实施的阵容轮换和赛后恢复策略有关。
