摘要

目的：我们比较了根据无氧速度储备（ASR）、30-15间歇体能测试（VIFT）和与最大摄氧量相关的速度（MAS）个性化设计的超大强度高强度间歇训练（HIIT）的适应性反应，以确定哪种方法更有利于不同特征运动员的相同适应性：方法：将 30 名国家级篮球运动员（年龄 = 28.4 [5] 岁；体重 = 88.9 [6.3] 千克；身高 = 190 [4.8] 厘米）随机分配到 3 个训练组，分别进行 2 组 4、6、8、6、8 和 10 分钟的跑步训练（从第一周到第六周），包括以 Δ%20ASR （MAS + 0.2 × ASR）、95%VIFT 和 120%MAS 的 15 秒跑步，两次努力之间恢复 15 秒，两组之间休息 3 分钟：结果：所有三种间歇干预措施都能在训练后显著提高最大摄氧量（V˙O2max）、氧脉搏（V˙O2/HR）、第一和第二通气阈值（VT1 和 VT2）、心输出量（Q˙max）、每搏量、峰值和平均功率输出、睾酮水平以及睾酮与皮质醇的比率（P<0.05）。6%）、VT2（21.8%、32.4%、56.7%）、Q˙max（8.2%、16.9%、28.8%）、冲程量（7.9%、15.2%、23.5%）、峰值功率输出（20%、22%、37.3%）、平均输出功率（21.1%、21.3%、32.5%）、睾酮（52.9%、61.6%、59.9%）和睾酮-皮质醇比率（55.1%、59.5%、57.8%）：结论：与使用 VIFT 或 MAS 进行的 HIIT 干预相比，在 Δ%20ASR 下进行的超极限 HIIT 可产生更均匀的生理适应。虽然荷尔蒙变化并不遵循这种方法，但所有方法都能诱导合成代谢效应。

Individualizing Basketball-Specific Interval Training Using Anaerobic Speed Reserve: Effects on Physiological and Hormonal Adaptations.

Purpose: We compared the adaptive responses to supramaximal high-intensity interval training (HIIT) individualized according to anaerobic speed reserve (ASR), the 30-15 Intermittent Fitness Test (VIFT), and velocity associated with maximum oxygen uptake (MAS) to determine which approach facilitates more identical adaptations across athletes with different profiles.

Methods: Thirty national-level basketball players (age = 28.4 [5] y; body mass = 88.9 [6.3] kg; height = 190 [4.8] cm) were randomly assigned to 3 training groups performing 2 sets of 4, 6, 8, 6, 8, and 10-minute runs (from first to sixth week, respectively), consisting of 15-second running at Δ%20ASR (MAS + 0.2 × ASR), 95%VIFT, and 120%MAS, with 15 seconds recovery between efforts and a 3-minute relief between sets.

Results: All 3 interval interventions significantly (P < .05) enhanced maximum oxygen uptake (V˙O2max), oxygen pulse (V˙O2/HR), first and second ventilatory threshold (VT1 and VT2), cardiac output (Q˙max), stroke volume, peak and average power output, testosterone levels, and testosterone-to-cortisol ratio following the training period. Different values of interindividual variability (coefficient of variation) for the percentage changes of the measured variables were observed in response to HIITASR, HIITvIFT, and HIITMAS for V˙O2max (8.7%, 18.8%, 34.6%, respectively), V˙O2/HR (9.5%, 15.0%, 28.6%), VT1 (9.6%, 19.6%, 34.6%), VT2 (21.8%, 32.4%, 56.7%), Q˙max (8.2%, 16.9%, 28.8%), stroke volume (7.9%, 15.2%, 23.5%), peak power output (20%, 22%, 37.3%), average power output (21.1%, 21.3%, 32.5%), testosterone (52.9%, 61.6%, 59.9%), and testosterone-to-cortisol ratio (55.1%, 59.5%, 57.8%).

Conclusions: Supramaximal HIIT performed at Δ%20ASR resulted in more uniform physiological adaptations than HIIT interventions prescribed using VIFT or MAS. Although hormonal changes do not follow this approach, all the approaches induced an anabolic effect.
