Outline of study design. The legend on the right indicates which measurements were carried out. MD = match day with “+”/“-” signs indicate the distance in days to the regular season matches, AM = morning, PM = afternoon/evening, CMJ = countermovement jump, LPS = local positioning system. The illustration is analogous to the one used in the pilot study18. When the entire squad participated in a midweek match on MD − 3, MD − 2 was scheduled as a rest day. In contrast, when only selected players participated in a midweek match on MD − 3, these players participated in regular training on MD − 2. Created with BioRender.com.
