Twenty-one women subjects were matched in terms of their Vo2max and assigned to one of two groups: (1) training at 30 s; or (2) 2 min with a 1:1 work: relief ratio (1:1 WR) before participating in a 7-week training programme which began at an intensity of 85% Vo2max and increased 5% every two weeks (90% and 95% Vo2max). The subjects trained to exhaustion four times per week. Maximal oxygen consumption (Vo2max), lactate threshold (Tlac) and ventilatory threshold (Tvent) were determined before and after the training programme. After training, there were significant increases (P < 0.05) in Vo2max (5% and 6%), Tlac (19.4% and 22.4%), and Tvent (19.5% and 18.5%). There were no significant group differences on any dependent measure but this research adds support to previous training studies in that a strong correlation (P < 0.05) between Tlac and Tvent is maintained from before to after the test. It was concluded that both formats of high intensity aerobic interval-training produce similar changes in Vo2max, Tlac and Tvent and that these changes appear to be independent of the length of the work interval.
21名女性受试者根据其最大摄氧量进行匹配，并被分为两组之一：（1）30秒训练组；或（2）1:1工作:休息比例（1:1 WR）的2分钟训练组，然后参加为期7周的训练计划，该计划从85%最大摄氧量的强度开始，每两周增加5%（90%和95%最大摄氧量）。受试者每周训练至 exhaustion 四次。在训练计划前后测定最大摄氧量（Vo2max）、乳酸阈值（Tlac）和通气阈值（Tvent）。训练后，Vo2max（5%和6%）、Tlac（19.4%和22.4%）和Tvent（19.5%和18.5%）有显著增加（P < 0.05）。在任何相关测量上均无显著的组间差异，但本研究为先前的训练研究提供了支持，因为从测试前到测试后，Tlac和Tvent之间保持了强相关性（P < 0.05）。研究得出结论，两种高强度有氧间歇训练形式在Vo2max、Tlac和Tvent方面产生相似的变化，并且这些变化似乎与工作间隔的长度无关。
