Re-warm-up activities are recommended in team sports due to loss of muscle temperature during half-time. This study aimed to evaluate the effects of a half-time re-warm-up strategy on female basketball players. Ten players U14, separated into two teams of five players, performed either a passive rest condition or repeated sprints (5×14 m) plus 2 min of a shooting wheel (re-warm-up condition), during the half-time break (10 min) of a simulated basketball match, where only the first three quarters were played. The re-warm-up did not elicit significant effects on jump performance and locomotory responses during the match, except for the distance covered at a very light speed, which was significantly higher than in the passive rest condition (1767 ± 206 vs 1529 ± 142 m; p < 0.05). Mean heart rate (74 ± 4 vs 70 ± 5%) and rate of perceived exertion (4.5 ± 1.5 vs 3.1 ± 1.44 a.u.) were higher in the re-warm-up condition during half-time (p < 0.05). In conclusion, performing re-warm-up activities based on sprints could be a valuable strategy to avoid the reduction of sport performance during prolonged breaks, but given the limitations of the study, these relationships need to be further explored in official competitions.
