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; < 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 ( < 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.
在团队运动中，由于中场休息期间肌肉温度下降，建议进行复温活动。本研究旨在评估中场休息时复温策略对女子篮球运动员的影响。10 名 U14 球员被分为两组，每组 5 名球员，在模拟篮球比赛的中场休息（10 分钟）期间，分别进行被动休息（对照组）或重复冲刺（5×14m）加 2 分钟投篮轮（复温组）。仅进行前三节比赛。复温组在比赛期间对跳跃表现和运动反应没有产生显著影响，但在极慢速度下的跑动距离明显高于被动休息组（1767±206 比 1529±142m；<0.05）。复温组在中场休息时的平均心率（74±4 比 70±5%）和感知用力程度（4.5±1.5 比 3.1±1.44 单位）更高（<0.05）。总之，基于冲刺的复温活动可能是一种避免长时间休息期间运动表现下降的有效策略，但鉴于本研究的局限性，这些关系需要在正式比赛中进一步探讨。
