This study investigated if the quantity of high-speed running (movements >15 km.h(-1) completed in the first 15 min of competitive football matches differed from that completed in the corresponding 15 min of the second half. 20 semi-professional soccer players (age 21.2±3.6 years, body mass 76.4±3.8 kg, height 1.89±0.05 m) participated in the study. 50 competitive soccer matches and 192 data files were analysed (4±2 files per match) using Global Positioning Satellite technology. Data were analysed using 2-way repeated measures ANOVA and Pearson correlations. No differences were found between the first 15 min of each half for the distance completed at high-speed (>15 km.h(-1) or sprinting (>21 km.h(-1), or in the number of sprints undertaken (p>0.05). However, total distance covered was shorter (1st half vs. 2nd half: 1746±220 vs. 1644±224 m; p<0.001) and mean speed lower (1st half vs. 2nd half: 7.0±0.9 vs. 6.6±0.9 km.h(-1); p<0.001) in the first 15 min of the second half compared to the first. The correlations between the duration of the half-time interval and the difference in the high-speed running or sprinting between first and second halves (0-15 min) were very small (r=0.08 [p=0.25] and r=0.04 [p=0.61] respectively). Therefore, this study did not find any difference between the amount of high-speed running and sprinting completed by semi-professional soccer players when the first 15 min of the first and second half of competitive matches were compared The maintenance of high-speed running and sprinting, as total distance and mean speed declined, may be a function of the pacing strategies adopted by players in competitive matches.
本研究旨在探讨职业足球运动员在比赛上下半时的前 15 分钟内，高速跑动（速度大于 15km/h）的跑动量是否存在差异。20 名半职业足球运动员（年龄 21.2±3.6 岁，体重 76.4±3.8kg，身高 1.89±0.05m）参与了本研究。使用全球定位卫星技术，分析了 50 场比赛和 192 个数据文件（每场比赛平均 4±2 个文件）。数据采用双因素重复测量方差分析和 Pearson 相关分析。上下半时的前 15 分钟内，高速跑动（速度大于 15km/h）和冲刺跑（速度大于 21km/h）的跑动距离以及冲刺跑的次数均无差异（p＞0.05）。然而，下半时的总跑动距离更短（上半时 vs 下半时：1746±220m vs 1644±224m；p＜0.001），平均速度更低（上半时 vs 下半时：7.0±0.9km/h vs 6.6±0.9km/h；p＜0.001）。上下半时之间中场休息时间的持续时间与上、下半时高速跑动和冲刺跑之间的差异呈非常小的相关性（r=0.08，p=0.25 和 r=0.04，p=0.61）。因此，本研究未发现职业足球运动员在上、下半时的前 15 分钟内，高速跑动和冲刺跑的量存在差异。随着总跑动距离和平均速度的下降，维持高速跑动和冲刺跑可能是运动员在比赛中采用的配速策略的一个功能。
