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).
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 de-conditioned 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.
when doing squats and other measurable exercises many people will count reps and set a goal within the 20 seconds of how many reps you can accomplish. This can only really be done after you have done a max effort version of the Tabata.... this will also be an easier way to track your progress than testing V02 max or any other or the correlates of success... I always test work capacity.
