Children and adults may react differently to warm‐up preservation due to different physical characteristics. This study aimed to: (i) assess the impact of different rewarm‐up routines in swimmers during a transition phase (20–25 min), including passive rest (SWU) or dynamic activities (RWU), on countermovement jump and swimming start performances, and (ii) explore potential RWU adaptations considering maturity offset (peak height velocity—PHV) and sex. Performance was analyzed using mixed effect ANCOVA, considering protocol, maturity offset (pre‐PHV, mid‐PHV, post‐PHV, and adv. post‐PHV), and sex. Results favored RWU over SWU with substantial magnitudes for jump height: pre‐PHV (min‐20, ES = 1.21; min‐25, ES = 1.65), mid‐PHV (min‐20, ES = 1.23; min‐25, ES = 1.14), post‐PHV (min‐20, ES = 1.37; min‐25, ES = 0.73), and adv. post‐PHV (min‐20, ES = 1.03; min‐25, ES = 0.65). Significant interactions at 25 min (p = 0.033, 0.047) showed that RWU outperformed SWU, especially in younger groups (pre‐PHV, mid‐PHV). RWU was superior to SWU for the reactive strength index at 20 min (p = 0.042) and 25 min (p = 0.047), with females having lower RSI than males at 20 min (p = 0.008, p = 0.015) and 25 min (p = 0.049) in later developmental stages. The flight distance (p = 0.009) and horizontal hip velocity (p = 0.014) revealed significant three‐way interactions, with the male adv. post‐PHV group responding better to RWU. Knee angular velocity was also higher after RWU, with male adv. post‐PHV group showing more pronounced improvements (p = 0.016). These results suggest that though RWU had higher influence in male adults, it is a valuable approach for varying ages athletes.

热身保存是否受生物成熟和性别的调节?对下肢表现的影响



由于身体特征不同,儿童和成人对热身保存的反应可能不同。本研究旨在:(i) 评估游泳者在过渡阶段(20-25 分钟)的不同热身程序的影响,包括被动休息 (SWU) 或动态活动 (RWU),对反向运动跳跃和游泳起跑表现的影响,以及 (ii) 探索潜在的 RWU 适应考虑到成熟偏移(峰值身高速度——PHV)和性别。使用混合效应 ANCOVA 分析性能,考虑方案、成熟度偏移量 (PHV 前、中期 PHV、PHV 后和 PHV 后高级)和性别。结果有利于 RWU 而不是 SWU,跳跃高度的幅度很大:PHV 前(min-20,ES = 1.21;min-25,ES = 1.65),中 PHV(min-20,ES = 1.23;min-25,ES = 1.14),PHV 后(min-20,ES = 1.37;min-25,ES = 0.73)和 adv.后 PHV(min-20,ES = 1.03;min-25,ES = 0.65)。25 分钟时的显着交互作用 (p = 0.033, 0.047) 表明 RWU 优于 SWU,尤其是在年轻群体 (pre-PHV, mid-PHV)。RWU 在 20 分钟 (p = 0.042) 和 25 分钟 (p = 0.047) 的反应强度指数优于 SWU,女性在 20 分钟 (p = 0.008,p = 0.015) 和 25 分钟 (p = 0.049) 的 RSI 低于男性在后期发育阶段。飞行距离 (p = 0.009) 和水平髋速 (p = 0.014) 揭示了显着的三向相互作用,男性 adv. PHV 后组对 RWU 的反应更好。RWU 后膝关节角速度也较高,男性 adv. PHV 后组显示出更明显的改善 (p = 0.016)。这些结果表明,尽管 RWU 对男性成年人的影响更大,但对于不同年龄的运动员来说,这是一种有价值的方法。
