AB  - The aim of this study is to investigate the biomechanical and muscular activation differences of countermovement jumps (CMJ) performed at different recovery durations after dynamic warm-up. Sixteen soccer players (U16; X ̅Age = 15.3 ± 0.9 years; X ̅Height = 173.3 ± 4.6 cm; X ̅BM = 62.9 ± 5.0 kg) voluntarily participated in the study. The soccer players performed two CMJ on a force platform at three different recovery durations (acute, 2nd minutes, and 4th minutes) following a 20-minute dynamic warm-up. The maximum jump height (JH) achieved under all conditions was evaluated for analysis. CMJ performance was analyzed in three phases (unweighting, braking, and maximum force). Kinematic (knee flexion angle), kinetic (JH, ground reaction forces-GRF), and electromyographic data (semitendinosus-ST) were recorded simultaneously during the jump. Differences in biomechanical and electromyographic parameters between CMJ tests performed at different recovery durations were analyzed using Repeated Measures ANOVA. According to the analysis results, JH, GRF, and ST muscle activity obtained after an optimal recovery interval of approximately 4 minutes were significantly higher than those obtained at other durations. This result indicates that the optimal recovery duration is approximately 4th minutes. Especially before high-intensity competitions, applying a recovery duration of approximately 4 minutes following warm-up may enhance performance in disciplines requiring explosive power, such as jumping and sprinting. Coaches and performance specialists should plan pre-competition preparation processes accordingly, considering the timing of the PAP effect.
