To examine whether preceding high-intensity race efforts in a competitive weekend affect pacing behavior and performance in elite short-track speed skaters.
Finishing and intermediate lap times were gathered from 500-, 1000-, and 1500-m short-track speed skating world cups during the seasons 2011-2016. The effect of preceding races on pacing behavior and performance was explored using 2 studies. Study I: The effect of competing in extra races due to the repechage (Rep) system, leading to an increased number of high-intensity race efforts prior to the subsequent main tournament race, was explored (500-m, n = 32; 1000-m, n = 34; and 1500-m, n = 47). Study II: The performance of skaters over the tournament days was evaluated (500-m, n = 129; 1000-m, n = 54; and 1500-m, n = 114). For both analytic approaches, a 2-way repeated-measures analysis of variance was used to assess differences in pacing and performance within skaters over the races.
An additional number of preceding high-intensity race efforts due to the Rep system reduced the qualification percentage in the first main tournament race for the next stage of competition in all events (500-m, direct qualification = 57.3%, Rep = 25.0%; 1000-m, direct = 44.2%, Rep = 28.3%; and 1500-m, direct = 27.1%, Rep = 18.2%) and led to a decreased pace in the initial 2 laps of the 500-m event. By contrast, tournament day (Saturday vs Sunday) only affected the pacing behavior of female skaters during the 1500-m event.
High-intensity race efforts earlier in the day affected pacing and performance of elite skaters, whereas the effect of high-intensity race efforts from the previous day seemed to be only marginal.
研究在一个竞争周末中之前的高强度比赛是否会影响精英短道速滑运动员的配速行为和表现。
在 2011 年至 2016 年的短道速滑世界杯比赛中，收集了 500 米、1000 米和 1500 米的比赛完赛时间和中间圈数。使用 2 项研究来探索之前比赛对配速行为和表现的影响。研究 I：研究由于复活赛（Rep）系统而参加额外比赛对后续主要锦标赛比赛之前高强度比赛次数增加的影响（500 米，n=32；1000 米，n=34；和 1500 米，n=47）。研究 II：评估运动员在整个比赛日的表现（500 米，n=129；1000 米，n=54；和 1500 米，n=114）。对于这两种分析方法，使用双向重复测量方差分析来评估运动员在比赛中的配速和表现的差异。
由于 Rep 系统，高强度比赛次数的增加降低了所有项目下一阶段比赛的第一阶段主锦标赛比赛的资格率（500 米，直接资格率=57.3%，Rep=25.0%；1000 米，直接资格率=44.2%，Rep=28.3%；和 1500 米，直接资格率=27.1%，Rep=18.2%），并导致 500 米比赛的前两圈速度下降。相比之下，仅比赛日（星期六对星期日）影响了女子 1500 米比赛中运动员的配速行为。
当天早些时候的高强度比赛会影响精英运动员的配速和表现，而前一天高强度比赛的影响似乎只有边际效应。
