Nature’s Need To Move – By Mike “Shark Man” Rutzen

Tabata hit at CERG

Tabata training is a very popular high intensity training protocol consisting of 20 seconds of all out effort, followed up by 10 second rest for a total of 4 minutes.  Tabata training shares the name with it’s inventor, Dr. Izumi Tabata, whom we had the pleasure of hosting at CERG today.

The concept of Tabata training was first entertained in 1984 in Norway, where Dr. Tabata was studying physiology along with Mr. Irisawa, a coach of the Japanese speed skating team.  The Tabata training protocol was first invented by Mr. Irisawa and was subsequently tested in the lab and established by Dr. Tabata. This protocol has been shown to deliver impressive improvements in fitness.

Tabata training is very simple to implement.  One can do it with a single movement (such as burpies), varying movements, or while running on a treadmill or cycling. Whichever way one chooses to exercise, the Tabata workout provides an effective full body anaerobic and anaerobic workout.  However, the Tabata-style workouts are very intense and their appropriateness should be assessed on individual basis.
