It is usually reported that the Tabata protocol (TP) is performed with eight bouts of 20:10 intervals at a load equivalent to 170% of i V̇ Omax. However, the feasibility of accumulating 160 s of work at 170% i V̇ Omax has been questioned. This article tested the intensity that would allow the performance of the original TP on a cycle ergometer, and measured the highest value of oxygen consumption (V̇ O) obtained during the TP and the time spent above 90% of the maximal oxygen uptake (V̇ Omax) during the TP performed at different intensities. Thirteen young active males (25.9 ± 5.5 years, 67.9 ± 9.2 kg, 1.70 ± 0.06 m, 23.6 ± 3.1 kg·m) participated in the study. Participants performed a graded exertion test (GXT) on a cycle ergometer to obtain maximum oxygen consumption (V̇ Omax) and the intensity associated with V̇ Omax (i V̇ Omax). V̇ O, maximal heart rate (HRmax), and number of bouts performed were evaluated during the TP performed at 115%, 130%, and 170% of i V̇ Omax. V̇ Omax, HRmax, and iV̇ Omax were 51.8 ± 8.0 mL.kg·min, 186 ± 10 bpm, and 204 ± 26 W, respectively. The number of bouts performed at 115% (7 ± 1 bouts) was higher than at 130% (5 ± 1 bouts) and 170% (4 ± 1 bouts) (p < .0001). The highest V̇ O achieved at 115%, 130%, and 170% of iV̇ Omax was 54.2 ± 7.9 mL·kg·min, 52.5 ± 8.1 mL·kg·min, and 49.6 ± 7.5 mL·kg·min, respectively. Non significant difference was found between the highest V̇ O achieved at different intensities, however qualitative magnitude-inference indicate a likely small effect between 115% and 170% of iV̇ Omax. Time spent above 90% of the V̇ Omax during the TP at 115% (50 ± 48 s) was higher than 170% (23 ± 21 s; p < 0.044) with a probably small effect. In conclusion, our data suggest that the adequate intensity to perform a similar number of bouts in the original TP is lower than previously proposed, and equivalent to 115% of the iV̇ Omax. In addition, intensities between 115 and 130% of the iV̇ Omax should be used to raise the time spent above 90% V̇Omax.
通常报道称，塔巴塔协议（TP）是在相当于个体最大摄氧量（iV̇Omax）170%的负荷下，以8组20:10的间歇进行。然而，在170% iV̇Omax下累积160秒运动的可行性受到了质疑。本文测试了在功率自行车上能够完成原始TP的强度，并测量了在TP期间获得的最高耗氧量（V̇O）以及在不同强度下进行TP时高于最大摄氧量（V̇Omax）90%的时间。13名年轻的活跃男性（25.9±5.5岁，67.9±9.2千克，1.70±0.06米，23.6±3.1千克·米）参与了该研究。参与者在功率自行车上进行了递增运动测试（GXT），以获得最大耗氧量（V̇Omax）以及与V̇Omax相关的强度（iV̇Omax）。在以iV̇Omax的115%、130%和170%进行TP期间，评估了V̇O、最大心率（HRmax）和完成的组数。V̇Omax、HRmax和iV̇Omax分别为51.8±8.0毫升·千克·分钟、186±10次/分钟和204±26瓦。在115%（每组7±1组）时完成的组数高于130%（每组5±1组）和170%（每组4±1组）（p <.0001）。在iV̇Omax的115%、130%和170%时达到的最高V̇O分别为54.2±7.9毫升·千克·分钟、52.5±8.1毫升·千克·分钟和49.6±7.5毫升·千克·分钟。在不同强度下达到的最高V̇O之间未发现显著差异，然而定性的量级推断表明在iV̇Omax的115%和170%之间可能存在较小影响。在115%的TP期间高于V̇Omax 90%的时间（50±48秒）高于170%（23±21秒；p < 0.044），影响可能较小。总之，我们的数据表明，在原始TP中完成相似组数的适当强度低于先前提出的强度，相当于iV̇Omax 的115%。此外，应使用iV̇Omax 的115%至130%之间的强度来增加高于90% V̇Omax的时间。
