At each of the 3 testing days (pre, 6d, 25d), players performed 3 performance tests. In order to assure constant testing conditions (22°C, 35% humidity), all tests were carried out on an indoor field. Before the tests, participants completed a 15-min warm-up of moderate running, short sprints, and stretching, followed by a 5-min rest. All performance tests were carried out in the same order starting with a Counter Movement Jump (CMJ) (coefficient of variation (CV) = 5.5%) (Marina et al., 2013)
