Yamashita, Y and Umemura, Y. Effect of high-intensity with short-duration re-warm up on subsequent performance in a cold environment. J Strength Cond Res 38(6): e280-e287, 2024-The aim of this study was to investigate the effect of high-intensity, short-duration re-warm-up (RW) during half time (HT) on subsequent performance in a cold environment. Eleven male subjects (age, 21 ± 2 years; height, 172.4 ± 4.5 cm; body mass, 65.6 ± 7.1 kg; V̇ o2 max, 47.5 ± 4.8 ml·kg -1 ·min -1 ) performed 2 experimental trials comprising 40 minutes of intermittent cycling exercise, which consisted of 15-second rest, 25-second unloading cycling, 10-second high-intensity cycling, and 70-second moderate-intensity cycling as the first half. In the second half, a cycling intermittent-sprint protocol (CISP) was performed, separated by a 15-minute HT period in cold conditions (5 °C, 50% relative humidity). Two experimental trials were included in a random order: (a) approximately 1 minute of high-intensity, short-duration RW (3 sets of 3-second maximal pedaling [body weight × 0.075 kp]) trial high-intensity intermittent cycling trials (HII); (b) 15 minutes of seated rest trial (CON). Cycling intermittent-sprint protocol consisted of 10 sets of a 2-minute exercise protocol, and each set consisted of 10-second rest, 5-second maximal pedaling (body weight × 0.075 kp), and 105-second active recovery at 50% maximum oxygen uptake (V̇ o2 max). Peak power output of 5-second maximal pedaling during CISP was higher in HII trials than in CON trials (HII: 807 ± 81 W, CON: 791 ± 78 W, p < 0.05). There was no significant difference in rectal temperature between trial types ( p > 0.05). These results suggest that high-intensity, short-duration RW may be a useful HT strategy for improving subsequent performance in cold environments.
山下 Y 和梅村 Y。高强度、短时间的恢复期对冷环境下后续表现的影响。J 力量与体能研究 38(6)：e280-e287，2024-本研究旨在探讨在冷环境下半时间（HT）期间进行高强度、短时间的再热身（RW）对随后表现的影响。11 名男性受试者（年龄 21 ± 2 岁；身高 172.4 ± 4.5cm；体重 65.6 ± 7.1kg；V̇o2 max 47.5 ± 4.8ml·kg -1 ·min -1 ）进行了 2 项实验性试验，包括 40 分钟的间歇性自行车运动，其中包括 15 秒的休息、25 秒的卸载自行车运动、10 秒的高强度自行车运动和 70 秒的中等强度自行车运动作为前半部分。在后半部分，进行了一个自行车间歇冲刺协议（CISP），在冷条件下（5°C，50%相对湿度）通过 15 分钟的 HT 期隔开。两个实验性试验以随机顺序包括在内：（a）大约 1 分钟的高强度、短时间的 RW（3 组 3 秒最大踩踏[体重×0.075kp]）试验高强度间歇自行车试验（HII）；（b）15 分钟的坐姿休息试验（CON）。自行车间歇冲刺协议由 10 组 2 分钟的运动协议组成，每组包括 10 秒的休息、5 秒的最大踩踏（体重×0.075kp）和 105 秒的主动恢复到 50%最大摄氧量（V̇o2 max）。在 CISP 期间的 5 秒最大踩踏的峰值功率输出在 HII 试验中高于 CON 试验（HII：807 ± 81W，CON：791 ± 78W，p<0.05）。试验类型之间的直肠温度没有显著差异（p>0.05）。这些结果表明，高强度、短时间的 RW 可能是一种在冷环境中提高后续表现的有用 HT 策略。
