本研究比较了最常见的绝对冲刺阈值(>25.2km/h)与相对和个性化阈值(>70%,>75%,>80%,>85%和>90%的峰值匹配速度)。二十名精英足球运动员,参加葡萄牙联赛的甲级联赛,在三十四场正式比赛中使用GNSS设备进行了监测。作为在整个季节中达到的个人最大速度,检索了峰值匹配速度。当速度超过绝对和相对阈值时,记录距离。计算峰值速度和覆盖距离的平均值±SD,和Pearson相关(r)和平均配对差异分析阈值之间的关系和差异。峰值匹配速度为32.9±1.4km/h。使用绝对阈值和相对阈值覆盖的距离之间的相关性非常强(>70%:r=0.84,p<.001;>75%:r=0.89,p<.001;和>80%:r=0.88,p<.001),强(>85%:r=0.79,p<.001),至中度(>90%:r=0.59,p<.001)。总的来说,>75%(ES:0.23[95%CI:0.16,0.31])和>90%(ES:-1.65[95CI:-1.85,-1.48])相对阈值呈现最小和最大差异,分别,绝对阈值。在考虑比赛位置时也发现了差异。虽然中央中场球员覆盖的距离在绝对阈值和>80%阈值之间相似(-0.03[-0.16,0.10]),在绝对阈值中,后卫覆盖的距离-1.88[-2.42-1.50])比在>80%阈值中更多。玩家覆盖的距离根据选定的阈值而变化,影响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不是较高的相对阈值显示出更大的相似性。
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.
