Due to physiological and anatomical sex differences, there are variations in the training response, and the recovery periods following exercise may be different. High-intensity interval training (HIIT) protocols are well-suited to differentially investigate the course of recovery. This study was conducted to determine sex-specific differences in the recovery following HIIT intervals interspersed with recovery phases of different lengths. Methods: Well-trained cyclists and triathletes (n = 11 females, n = 11 males) participated in this study. There were no significant sex differences in maximal heart rate (HR), relative peak power to body mass and fat-free mass, training volume, and VO_2max-percentiles (females: 91.8 ± 5.5 %, males: 94.6 ± 5.4 %). A 30 s Wingate test was performed four times, separated by different active recovery periods (1, 3, or 10 min). Lactate, HR, oxygen uptake, and subjective rating of exertion and recovery were determined. Results: For the recovery time of three and ten minutes, men showed significantly higher lactate concentrations (p = 0.04, p = 0.004). Contrary, HR recovery and subjective recovery were significant slower in women than in men. Conclusion: During HIIT, women may be more resistant to fatigue and have a greater ability to recover metabolically, but have a slower HR and subjective recovery.

从不同的高强度间歇训练规程中恢复：比较训练有素的男女

由于生理和解剖学上的性别差异，训练反应会有所不同，并且运动后的恢复期可能会有所不同。高强度间歇训练（HIIT）协议非常适合差异研究恢复过程。进行这项研究是为了确定HIIT间隔后的恢复中的性别特异性差异，以及不同长度的恢复阶段。方法：训练有素的自行车手和铁人三项运动员（n = 11女，n = 11男）参加了这项研究。最大心率（HR），相对体重和无脂肪体重，训练量和VO _2max的性别无明显差异-百分位数（女性：91.8±5.5％，男性：94.6±5.4％）。30秒钟的Wingate测试执行了四次，分别由不同的主动恢复周期（1、3或10分钟）分隔。确定乳酸， HR ，摄氧量，劳累和恢复的主观评级。结果：在三分钟和十分钟的恢复时间内，男性的乳酸浓度明显升高（p = 0.04，p = 0.004）。相反，女性的HR恢复和主观恢复显着慢于男性。结论：在HIIT期间，女性可能对疲劳更有抵抗力，并具有更高的代谢恢复能力，但HR和主观恢复较慢。
