This study assessed the internal and external workload of starters and non-starters in a professional top-level soccer team during a congested fixture period. Twenty Serie A soccer players were monitored in this study during two mesocycles of 21 days each. Starters and non-starters were divided based on the match time played in each mesocycle. The following metrics were recorded: exposure time, total distance, relative total distance, high-speed running distance over 20 km·h, very high-speed running distance over 25 km·h, individual very high-speed distance over 80% of maximum peak speed, and rating of perceived exertion. Differences between starters and non-starters were found for: exposure time (effect size=large to very large), rating of perceived exertion (large to very large), total distance (large to very large), and individual very high-speed distance over 80% of maximum peak speed (moderate to large). Furthermore, differences for relative total distance, high-speed running distance over 20 km·h and very high-speed running distance over 25 km·h were small to moderate, but not significant. This study reports that during congested fixture periods, starters had higher exposure time, rating of perceived exertion, total distance, and individual very high-speed distance over 80% of maximum peak speed than non-starters.
本研究评估了在一个密集赛程期间，职业顶级足球俱乐部的首发球员和非首发球员的内部和外部工作负荷。在这项研究中，有 20 名意甲足球运动员在两个为期 21 天的中周期内接受了监测。首发球员和非首发球员根据每个中周期的比赛时间进行了划分。记录了以下指标：暴露时间、总距离、相对总距离、超过 20km·h 的高速跑距离、超过 25km·h 的超高跑距离、个人最高速度 80%以上的超高跑距离和感觉用力评级。首发球员和非首发球员在暴露时间（效应大小为大到非常大）、感觉用力评级（大到非常大）、总距离（大到非常大）和个人最高速度 80%以上的超高跑距离（中等到大）方面存在差异。此外，相对总距离、超过 20km·h 的高速跑距离和超过 25km·h 的超高跑距离的差异较小到中等，但无统计学意义。本研究报告称，在密集赛程期间，首发球员的暴露时间、感觉用力评级、总距离和个人最高速度 80%以上的超高跑距离高于非首发球员。
