This study compared the most common absolute sprint threshold (> 25.2 km/h) with relative and individualized thresholds (> 70%, > 75%, > 80%, > 85% and > 90% of peak match speed). Twenty elite soccer players, competing in the first division of the Portuguese League, were monitored using GNSS equipment during thirty-four official matches. Peak match speed was retrieved as the individual maximal speed reached during the full season. Distances were registered when speed overcame the absolute and the relative thresholds. Mean ± SD of peak speeds and distances covered were calculated, and Pearson correlation () and mean paired differences were performed to analyze relationships and differences between thresholds. The peak match speed was 32.9 ± 1.4 km/h. Correlations between distances covered using the absolute and relative thresholds varied from very strong (> 70%: = 0.84, < .001; > 75%: = 0.89, < .001; and > 80%: = 0.88, < .001), strong (> 85%: = 0.79, < .001), to moderate (> 90%: = 0.59, < .001). Overall, the > 75% (ES: 0.23 [95% CI: 0.16, 0.31]) and the > 90% (ES: -1.65 [95%CI: -1.85, -1.48]) relative thresholds presented the smallest and largest differences, respectively, with the absolute threshold. Differences were also found when considering the playing positions. While the distances covered by central midfielders were similar between the absolute and > 80% thresholds (-0.03 [-0.16, 0.10]), fullbacks covered largely more distance -1.88 [-2.42 -1.50]) in the absolute threshold than in the > 80% threshold. The distances covered by players varied based on the selected threshold, affecting the distances covered by different playing positions. Being the highest speed threshold within displacements thresholds, the absolute sprint threshold showed greater similarity to lower rather than higher relative thresholds.
本研究将最常见的绝对冲刺阈值(>25.2公里/小时)与相对和个性化阈值(>峰值比赛速度的70%、>75%、>80%、>85%和>90%)进行了比较。20名参加葡萄牙联赛第一级别比赛的精英足球运动员,在34场正式比赛期间使用全球导航卫星系统设备进行监测。将峰值比赛速度作为整个赛季中个人达到的最大速度。当速度超过绝对阈值和相对阈值时记录距离。计算峰值速度和所覆盖距离的平均值±标准差,并进行皮尔逊相关性()和平均配对差异分析,以分析阈值之间的关系和差异。峰值比赛速度为32.9±1.4公里/小时。使用绝对阈值和相对阈值所覆盖距离之间的相关性从非常强(>70%:=0.84,<.001;>75%:=0.89,<.001;>80%:=0.88,<.001)、强(>85%:=0.79,<.001)到中等(>90%:=0.59,<.001)不等。总体而言,>75%(效应量:0.23[95%置信区间:0.16,0.31])和>90%(效应量:-1.65[95%置信区间:-1.85,-1.48])相对阈值与绝对阈值的差异分别最小和最大。在考虑比赛位置时也发现了差异。虽然中场中路球员在绝对阈值和>80%阈值之间所覆盖的距离相似(-0.03[-0.16,0.10]),但边后卫在绝对阈值下所覆盖的距离比在>80%阈值下大得多(-1.88[-2.42,-1.50])。球员所覆盖的距离因所选阈值而异,这影响了不同比赛位置所覆盖的距离。作为位移阈值内的最高速度阈值,绝对冲刺阈值与较低而非较高的相对阈值表现出更大的相似性。
