Tabata Intervals



By Ross Enamait - Published in 2003




As I am writing this article, I am happy to report that the temperature
is a balmy 10 degrees Fahrenheit outside. The wind chill is –4. Last
week, the wind chill hit –30 degrees. There is snow on the ground and
it is cold. During this time of the year, you may have difficulty
running outside. I personally enjoy running in the snow, but you may
not have access to a convenient running location.

What can you do? Will you sacrifice conditioning because of a little cold weather?


Of course not!


There are several indoor options that you can use to crank up the
intensity of your conditioning session. Tabata Intervals are just one
example. The phrase Tabata Interval
originated from a study performed by Dr. Izumi Tabata (and colleagues)
at the National Institute of Fitness and Sports in Tokyo, Japan.

Below I have provided an abstract from this study.

ABSTRACT Effects of moderate-intensity endurance and high-intensity intermittent training on anaerobic capacity and VO2max. Tabata I, Nishimura K, Kouzaki M, Hirai Y, Ogita F, Miyachi M, Yamamoto K. Department of Physiology and Biomechanics, National Institute of Fitness and Sports, Kagoshima Prefecture, Japan. This study consists of two training experiments using a mechanically braked cycle ergometer. First, the effect of 6 wk of moderate-intensity endurance training (intensity: 70% of maximal oxygen uptake (VO2max), 60 min.d-1, 5 d.wk-1) on the anaerobic capacity (the maximal accumulated oxygen deficit) and VO2max was evaluated. After the training, the anaerobic capacity did not increase significantly (P > 0.10), while VO2max increased from 53 +/- 5 ml.kg-1 min-1 to 58 +/- 3 ml.kg-1.min-1 (P < 0.01) (mean +/- SD). Second, to quantify the effect of high-intensity intermittent training on energy release, seven subjects performed an intermittent training exercise 5 d.wk-1 for 6 wk. The exhaustive intermittent training consisted of seven to eight sets of 20-s exercise at an intensity of about 170% of VO2max with a 10-s rest between each bout. After the training period, VO2max increased by 7 ml.kg-1.min-1, while the anaerobic capacity increased by 28%. In conclusion, this study showed that moderate-intensity aerobic training that improves the maximal aerobic power does not change anaerobic capacity and that adequate high-intensity intermittent training may improve both anaerobic and aerobic energy supplying systems significantly, probably through imposing intensive stimuli on both systems.

Tabata Summary



Tabata Intervals consist of 20 seconds of maximum intensity exercise,
followed by 10 seconds of rest. This cycle is repeated 8 times (for a
total of 4-minutes). Although Dr. Tabata used a mechanically braked
cycle ergometer, you can apply this protocol to almost any exercise. A
few popular examples include hitting a heavy bag, sprinting, jumping
rope, or performing bodyweight calisthenics (ex. squats and pushups).

Your first reaction might be, “How effective can this protocol be with just 4 minutes of exercise?”


Let me answer this question for you… VERY EFFECTIVE!


You will be amazed at how intense 4 minutes of exercise will feel.
These intervals will tax both the aerobic and anaerobic energy systems.
Tabata Intervals are excellent for those athletes who participate in
high intensity sports such as boxing, MMA, or wrestling.

After just 6 weeks of testing, Dr. Tabata noted a 28% increase in
anaerobic capacity along with a 14% increase in V02Max. These results
were witnessed by physically fit athletes. Many tests are conducted on
deconditioned subjects, which leads to results that are difficult to
evaluate. Dr. Tabata's test was much more effective, as it produced a
positive response on individuals who were already in shape.

This form of training is also effective for fat loss. Tabata Intervals
will raise your body’s metabolic rate long after the exercise session
is completed. You will continue to burn fat throughout the day. Many
recent studies have confirmed that the powerful "after-effect" of
interval training is much more effective (for fat loss) than
low-intensity, continuous exercise.

As mentioned, the Tabata protocol can be applied to almost any
exercise. The most obvious choice is outdoor sprinting. For example,
sprint 20 seconds, then rest (walk) 10 seconds, and continue until you
have completed 8 x 20 second sprints. Always begin with a moderate
warm-up and cool down session.

A winter friendly option can include a variety of exercises. Below I have provided one sample workout.


Tabata Workout Sample

• Jump Rope (High Knee jump rope style, sprint in place)
  
• Pushups
  
• Squats
  
• Chinnies
  

This workout will consist of 4 separate Tabata Intervals, each
consisting of 4 minutes. The total workout will last 16 minutes. You
can perform this workout indoors.

Another great Tabata workout can be performed on the heavy bag. Punch
non-stop for 20-second intervals, followed by 10 seconds of rest. You
will be surprised at the difficulty of this 4-minute heavy bag session.


Incorporate variety into your Tabata Interval workouts. A few sessions per week will offer plenty of intensity.
