Abstract

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 (r) 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%: r = 0.84, p < .001; > 75%: r = 0.89, p < .001; and > 80%: r = 0.88, p < .001), strong (> 85%: r = 0.79, p < .001), to moderate (> 90%: r = 0.59, p < .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.

分析足球比赛的短跑距离:基于 GPS 的绝对阈值和相对阈值的比较。
这项研究将最常见的绝对冲刺阈值(> 25.2 公里/小时)与相对阈值和个性化阈值(> 70%、> 75%、> 80%、> 85% 和> 90% 的比赛峰值速度)进行了比较。在 34 场正式比赛中,使用全球导航卫星系统设备对参加葡萄牙甲级联赛的 20 名精英足球运动员进行了监测。比赛峰值速度是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,则记录距离。计算了峰值速度和距离的平均值(± SD),并通过皮尔逊相关性(r)和平均配对差异来分析阈值之间的关系和差异。峰值匹配速度为 32.9 ± 1.4 km/h。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%:r = 0.84,p < .001;> 75%:r = 0.89,p < .001;> 80%:r = 0.88,p < .001)、强(> 85%:r = 0.79,p < .001)到中等(> 90%:r = 0.59,p < .001)不等。总体而言,相对阈值 > 75% (ES: 0.23 [95%CI: 0.16, 0.31])和 > 90% (ES: -1.65 [95%CI: -1.85, -1.48]) 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。中场球员在绝对临界值和大于 80% 临界值时的覆盖距离相似(-0.03 [-0.16, 0.10]),而后卫在绝对临界值时的覆盖距离要比大于 80% 临界值时的覆盖距离大得多(-1.88 [-2.42 -1.50] )。根据所选临界值的不同,球员的覆盖距离也不同,这影响了不同位置球员的覆盖距离。作为位移阈值中最高的速度阈值,绝对冲刺阈值与较低而非较高的相对阈值有更大的相似性。
