RT info:eu-repo/semantics/article T1 Recovery kinetics of countermovement jump performance after soccer matches: differences between starters and non-starters: Recovery of countermovement jump performance in soccer A1 Marqués-Jiménez, Diego A1 Castillo Alvira, Daniel A1 Ramírez Jiménez, Miguel A1 Izquierdo Velasco, José María AB The present study aimed to explore differences in the recovery kinetics of countermovement jump performance in starting and non-starting soccer players after the competition. Twelve male outfield players (age: 27.05 ± 4.31 years; height: 177.50 ± 4.56 cm; body mass: 71.48 ± 4.63 kg) were included in this case series study. It included two data collection periods within a single competitive season, each encompassing one official match and the subsequent 48-h recovery period. Each participant was included in the starting line-up only in one match. Countermovement jump performance was monitored on each morning of the match-day, and subsequent measurements were acquired immediately post-, at 24-h and at 48-h post-match. Both output-orientated and time-based metrics were obtained from each jump. Afterwards, each participant's data was compared between two conditions: when they were a starter (included in the starting line-up) and when they were a non-starter (not included in the starting line-up, regardless of match playing time). Time-related changes in performance within each group were determined using a repeated-measures ANOVA with Holm post hoc analysis and the Cohen's d effect size statistic. Group differences in performance at post-match, 24-h, and 48-h post-match were determined by conducting ANCOVA with Holm post hoc analysis and partial eta squared, using pre-match values as covariates. Compared to baseline, jump height and propulsive impulse were significantly decreased at 24-h post-match only in starters (p < 0.001), while no significant time-related changes were found in non-starters. Compared to non-starters, starters exhibited a longer propulsive phase duration post-match (p = 0.037), lower jump height and propulsive impulse at 24-h post-match (p = 0.019, p = 0.005, respectively), and lower absolute peak power at 48-h post-match (p = 0.042). Thus, both jump outcome and movement strategy responses to neuromuscular fatigue evidenced a faster recovery of countermovement jump performance in non-starters players.
