Purpose:
This exploratory study investigated the effects of a 3-minute re-warm-up protocol implemented during halftime on sprint and jump performance in female soccer players.
Methods:
Twenty-two professional female soccer players from 2 Portuguese clubs from First and Second Divisions were randomly assigned to either a control group (G1: passive rest) or an experimental group (G2: re-warm-up). The Integrated Re-warm-up soccer protocol, performed by G2, consisted of 6 FIFA 11+ power exercises and a small-sided game. Performance was measured using a 20-m sprint and countermovement jump at baseline (post-warm-up) and after the half-time intervention. A 2-way analysis of variance (group × time) was conducted for analysis, with effect sizes reported as partial eta squared (ηp2).
Results:
A time × group interaction was found for sprint performance (F = 6.66, P = .019, ηp2=.27), favoring the experimental group (G1: -0.25 s vs G2: -0.40 s). For countermovement jump performance, no time × group interaction was observed (F = 2.66, P = .483, ηp2=.02), although a main effect of time effect was detected (F = 10.34, P = .005, ηp2=.36); both groups showed a decrease in jump height, but to a lesser extent in the re-warm-up group (G1: -2.85 cm vs G2: -1.82 cm).
Conclusions:
A brief 3-minute re-warm-up protocol implemented at halftime improved sprint performance compared to passive rest. These findings suggest that time-efficient re-warm-up protocols, combining FIFA 11+ power exercises and small-sided games may be useful during the half-time interval in female soccer players.
