Group two showed a greater increase than group one in both aerobic and anaerobic performance. Tabata is quick, effective and intense. You are asked to work as hard as you can with each exercise for 20 seconds followed by a second rest. A traditional Tabata would include 4 exercises for 4 minutes.
We encourage you to try the program above, but go for 8 minutes. This means you will repeat each exercise 4 times. It will be over before you know it and the benefits of your hard work will last long after the workout is finished. So while it is used by most people to get fit — or by fit people to get even fitter — it also burns fat.
It's slightly surprising, therefore, that the plan is still the preserve of the serious athlete and musclehead crowd — although that may change now that Tabata has agreed a deal with Universal Studios that will lead to a network of instructors and a DVD range released towards the end of the year. So should we all start incorporating this plan into our fitness regimens?
Richard Scrivener, a former assistant strength and conditioning coach at Northampton Saints rugby club, says that while the benefits are clear, Tabatas are an addition, not a replacement, to a favoured sport or training method. This will unload the skeleton and give joints the chance to rest and recover, especially if one is prone to niggles or has a history of injuries — and you would probably therefore get more out of the long runs when you do undertake them.
Gym rats can benefit by doing three strength sessions and three Tabatas a week. And the rest of us can build up session by session, week by week, all the time knowing that it will never get easier because every session calls for maximum effort.
That's the dastardly genius of the protocol: it is unrelenting — and effective. Look for this banner for recommended activities. Cancel Yes. Join Active or Sign In. All rights reserved. Go Premium.

Activities near you will have this indicator. Specific training induces increased expressions of proteins that have specific physiological functions in skeletal muscles recruited by training.
For example, aerobic training increases the enzyme activities of citrate synthase CS, which is a key enzyme for oxidative metabolism [ 40 ] , and high-intensity exercise training increases glycogen phosphorylase and phosphofructokinase PFK , which are possible rate-limiting enzymes of anaerobic metabolism [ 41 , 42 ]. Sprint training with a very short duration of exercise i. Skeletal muscle adaptation to Tabata training was recently reported [ 44 ]. These elevated enzyme activities may have contributed to the increases in the V O 2 max 9.
Those results suggested that dozens of proteins that are known to be increased by this transcriptional coactivator may be increased after Tabata training [ 47 ].
Since it was not feasible for rats to run intermittently at a high intensity speed on a treadmill, swimming was introduced to model Tabata training for rats. The reason that this protocol has been used in previous studies is that the protocol was shown, by trial and error, to raise the blood lactate concentration to levels that were similar to those measured for humans and to elevate the enzyme activity of citrate synthase, which is an oxidative enzyme in mitochondria [ 48 ].
Indeed, the above-cited clinical study [ 44 ] demonstrated that 79 genes including genes involved in glucose metabolism, the mitochondria membrane, the extracellular matrix, and angiogenesis were increased in skeletal muscle by training. A proteomics analysis of rat muscles after Tabata-model training revealed that the protein expression of glycogen phosphorylase the first enzyme of glycogenolysis was increased [ 49 ]. It is well documented that low-volume interval training increases skeletal muscle oxidative enzymes [ 50 ].
Robinson et al. In terms of the increase in the V O 2 max after HIIT, there has been some disagreement regarding whether the main location of the occurrence of adaptation is central cardiorespiratory: cardiac output or peripheral skeletal muscle: metabolic enzymes.
However, Burgomaster et al. Daussin et al. Macpherson et al. The authors of the latter study attributed the initial increase in cardiac output after the early phase of the high-intensity interval training to plasma volume expansion [ 55 ], which was apt to occur in their sedentary subjects with lower V O 2 max values compared to those of the recreationally active subjects of the Macpherson et al.
Further research is necessary to address these findings. In the original Tabata et al. However, as Fox et al. This transcriptional coactivator activates the transcription of proteins that have physiological functions, and its activity remained high for several days.
This enhanced capacity allows more muscle lactate formation, which results in proportional glycolytic ATP production for high-intensity exercises. Shark et al. Endurance training increases capillary density [ 59 ]. Cocks et al. Using an animal model of Tabata training, Hasegawa et al.
This investigation showed that both animal model of Tabata training and aerobic training induced increased expression of eNOS, which produces nitric oxide NOx , which subsequently may dilate arteries, suggesting that Tabata training might improve arterial function via the same mechanism as conventional aerobic training and may decrease the risk of cardiovascular events.
There has been a rumor that Tabata training is effective for losing body weight. However, the energy consumption during a high-intensity short-duration training exercise is negligible.
The thermic effects of meals ingested after Tabata training have also not been evaluated. In contrast, a recent investigation reported that oxygen uptake after lunch and supper ingested 1. This study showed that EPOC during the first 1. Energy consumption calculated from oxygen uptake during min warm up exercise WU , Tabata training exercise was EPOC during the first 1.
Summation of the previously described 4 energy consumption are This value that is regarded as elevated energy consumption by Tabata training exercise could be the lowest in terms of securing weight reduction.
However, after 6-week Tabata training, body weight was not changed [ 13 ]. Therefore, weight reducing effect of Tabata training seems to be minimal. The Tsuji et al. The first article regarding Tabata training was published over 30 years ago, and no further paper was published by the authors of the original article until recently.
There has thus been some confusion about Tabata training, especially concerning the methodology. The following practical tips for executing authentic Tabata training are presented in order to prevent the misunderstanding of Tabata training in future studies. First, before an individual engages in Tabata training, warming up for 10 min at approx. The exercise intensity should be determined individually. The subject should then be instructed to continue bicycling until exhaustion described below after a s cycling bout with a s rest interval.
If the subject can continue to bicycle for more than eight sets, the exercise intensity should be increased. If the subject cannot bike for less than six sets, the exercise intensity is reduced. Exhaustion during bicycle exercise is determined as follows. For bicycling exercise, it is important to raise the pedaling frequency to the fixed rate as soon as possible to set the correct load for the subject.
A pedaling frequency of rpm might be good for cyclists. In the original Tabata study, 90 rpm was used. The reason why we use a higher pedaling frequency than that used for normal bicycle exercise 50—70 rpm is that without such a high pedaling frequency, a high-enough load cannot be set for heavy-weight top athletes. In the original Tabata training experiments, Monark bicycles whose highest load is 7 kP were used, but even with such a heavy weight, the load is not high enough to exhaust elite athletes within 7—8 sets of Tabata training if 50—70 rpm is used.
By using 90 rpm, an adequate work rate, which is a function of weight kP and rpm, is assured for highly trained athletes. Because high-intensity exercise may reduce immunological functions [ 65 ], it can be speculated that in terms of the prevention of any type of cancer that may be initiated by low immunological function, high-intensity exercise training may have no effects or adverse effects.
However, the results of a recent study suggested that Tabata training may help prevent colon cancer by enhancing the secretion and elevating the blood concentration of secreted protein acidic and rich in cysteine SPARC Fig.
These biological results may explain the epidemiological finding that vigorous exercise may help prevent and not worsen colon cancer [ 67 , 68 ].
Another recent investigation indicated that this result may reflect the evidence that Tabata training does not reduce immunological function [ 69 ]. Martin Gibala to the popularity of HIIT among scientists and exercisers should be appreciated [ 52 , 70 — 72 ]. He and his team conducted numerous studies on skeletal muscle adaptation after HIIT. Scientific evidence from the sport fields is thus limited. Ravier reported that a running training protocol that was similar to Tabata training elevated the V O 2 max and MAOD of karate athletes who also performed other types of repetitive exercise [ 73 ].
Evaluations of top athletes by researchers will help elucidate the effects of Tabata training on the performance of various sports. A determination of the effects of Tabata training using exercises that simulate the activities of specific sports is valuable in light of the specificity of training and training effects on sports performance. However, in terms of effects on aerobic and anaerobic energy-releasing systems, there is not enough published data about training methods that follow protocols similar to Tabata training but use other types of exercise including running and various body-weight bearing exercises, which are frequently adopted by competitive runners and recreational exercisers, respectively.
Effects of such exercise training on V O 2 max have been reported [ 74 — 80 ], and such research on similar protocol training methods is expected to determine the effects on anaerobic energy-releasing systems. Since Tabata training induces the expression of proteins related not only to sports performance but also to health promotion [ 44 ], more research on the possible effects of Tabata training and other training that uses a Tabata protocol on health outcomes is expected.
Tabata training is very demanding [ 33 ], and thus participation in Tabata training might be limited to highly motivated athletes who are familiar with the scientific evidence regarding Tabata training or are persuaded to engage in the training by coaches who know the Tabata training research findings.
In addition, the dropout rate in the Chuiesiri et al. These rates may indicate that the HIIT was tolerable and positively accepted. However, the results of another investigation suggested that training at high intensities would be rated as not enjoyable [ 81 ].
