Morning ratings of fatigue, sleep quality, and delayed-onset muscle soreness (DOMS), as well as submaximal exercise heart rate (HRex), postexercise heart-rate recovery (HRR%), and heart-rate variability (HRV) were recorded before match day and 1, 2, and 4 d postmatch. Data were collected for a median duration of 3 wk (range 1\u201313) and reduced to a typical weekly cycle including no midweek match and a weekend match day.

Perceived fatigue, sleep quality, and DOMS improved by 17\u201326% from postmatch day to 3 d postmatch, with further smaller (7%\u201314%) improvements occurring between 4 d postmatch and prematch day (<jats:italic>P<\/jats:italic> &lt; .01).
