Countermovement jump
Each testing session started with the CMJ test on a force plate (Muscle lab, Ergotest Technology AS, Porsgrunn, Norway), which was used to evaluate jump height (cm), maximal power (W), rate of force development (kN/s), and peak force (N/kg). The CMJ was performed with feet shoulder-width apart and hands on the hips during the whole jump. From a standing position, participants were required to squat to a self-selected depth and then perform a maximal vertical jump. The feet had to be straight during the flight time. Jump height was calculated with impulse (Muscle lab, Ergotest Technology AS, Porsgrunn, Norway). As a warm-up, the participants performed three submaximal CMJ trials with approximately 50%, 75%, and 90% intensity (45 s of rest between attempts). Following the warm-up, three CMJ attempts were performed, and the participants rested 15 s between each attempt. Highest values for each of the analyzed variables were used for statistical analysis.
