This study investigated the effects of match location, quality of opposition (classified into: strong [1st to 4th position]; intermediate [5th to 15th position]; weak [16th to 20th position]), and match outcome on the match running performance of starters and non-starters from a top elite Brazilian soccer team. Absolute measures were calculated using total distance, high-speed (19.8–25.2 km·h−1), sprinting (≥ 25.2 km·h−1), total distance high-acceleration (> 2m·s2 ), and deceleration (< −2m·s2) were recorded by GPS units from a sample of young soccer players ( N = 25) in a total of 17 matches. Relative measures were calculated by dividing absolute measures by the total duration of the matches. Non-starters covered greater total distance ( p = 0.02), sprinting ( p = 0.02), high-acceleration and deceleration ( p = 0.04), sprinting distance relative per minute played ( p = 0.005), and high-acceleration and deceleration relative per minute played ( p < 0.001) when the team plays at home, strong opponents, and wins the matches. Starters covered greater total distance in high-speed running ( p = 0.04), high-acceleration and deceleration ( p = 0.03), and high-speed running relative per minute played ( p = 0.04) when the team plays strong opponents and wins the matches. These findings highlight the impact of contextual factors during matches on the locomotor performance of young soccer players.

情境因素对青年男足球精英运动员首发和非首发运动员比赛跑动表现的影响

本研究调查了比赛地点、对手质量（分为：强[第1至4位]；中[第5至15位]；弱[第16至20位]）和比赛结果对比赛跑动表现的影响。来自巴西顶级精英足球队的首发球员和非首发球员。绝对测量值使用总距离、高速（19.8–25.2 km·h−1）、冲刺（≥25.2公里·小时−1),总距离高加速(>2m·s2) 和减速度 (< −2m·s2）是由 GPS 装置记录的年轻足球运动员样本（N = 25）总共 17 场比赛的数据。相对测量值是通过将绝对测量值除以比赛总持续时间来计算的。非首发选手的总距离更长 (p = 0.02)、冲刺 (p = 0.02)、高加速和减速 (p = 0.04)、每分钟相对冲刺距离 (p = 0.005) 以及相对高加速和减速当球队在主场、强大的对手并赢得比赛时，每分钟的比赛次数 (p < 0.001)。当球队与强敌交手并赢得比赛时，先发球员在高速跑（p = 0.04）、高加速和减速（p = 0.03）以及高速跑相对每分钟跑动距离（p = 0.04）中所跑的总距离更大。火柴。这些发现强调了比赛期间的背景因素对年轻足球运动员运动表现的影响。
