耐力运动训练研究经常显示，随着训练的进行，VO(2)max的变化不大，一些受试者的反应非常有限。相比之下，使用间歇训练(IT)或联合使用IT和连续训练(CT)的研究报告了最大摄氧量(VO(2)max)的平均增幅高达1.0%，与L的水平相似。分钟(-1)。这引发了人们对运动强度的作用和最大摄氧量的可训练性的质疑。为了解决这个问题，我们分析了1965-2012年间发表的英文版IT和IT/CT研究。纳入标准是：1)>；=3个健康的久坐不动的人/3个娱乐活跃的人=3天/3周，4)>；=10分钟的高强度工作，5)>；=1：1的工作/休息比，6)结果报告为平均+/-SD或SE、变化范围或个人数据。由于异质性(I-2值为70)，数据的统计合成使用了随机效应模型。感兴趣的汇总统计数据是最大摄氧量的变化。37项研究共确定了334名受试者(120名女性)。参与者被分成40个不同的训练组，因此分析单位是40而不是37。VO(2)max增加0.51%，L。MIN(-1)(95%CI：0.43~0.60 L。Min(-1))。9项研究的子集，72名受试者，具有更长的间隔，显示出更大的(类似于0.80.9 L)。Min(-1))VO(2)max的变化，所有受试者均有明显反应。这些结果表明，关于可训练性和VO(2)最大值的想法应该通过标准化的IT或IT/CT培训计划来进一步评估。
Endurance exercise training studies frequently show modest changes in VO(2)max with training and very limited responses in some subjects. By contrast, studies using interval training (IT) or combined IT and continuous training (CT) have reported mean increases in VO(2)max of up to similar to 1.0 L . min(-1). This raises questions about the role of exercise intensity and the trainability of VO(2)max. To address this topic we analyzed IT and IT/CT studies published in English from 1965-2012. Inclusion criteria were: 1)>= 3 healthy sedentary/3recreationally active humans = 3 days/3week, 4) >= 10 minutes of high intensity work, 5) >= 1:1 work/rest ratio, and 6) results reported as mean +/- SD or SE, ranges of change, or individual data. Due to heterogeneity (I-2 value of 70), statistical synthesis of the data used a random effects model. The summary statistic of interest was the change in VO2max. A total of 334 subjects (120 women) from 37 studies were identified. Participants were grouped into 40 distinct training groups, so the unit of analysis was 40 rather than 37. An increase in VO(2)max of 0.51 L . min(-1) (95% CI: 0.43 to 0.60 L . min(-1)) was observed. A subset of 9 studies, with 72 subjects, that featured longer intervals showed even larger (similar to 0.8-0.9 L . min(-1)) changes in VO(2)max with evidence of a marked response in all subjects. These results suggest that ideas about trainability and VO(2)max should be further evaluated with standardized IT or IT/CT training programs.
