What the heck is a Tabata? The concept originated from a study published in 1996 by Izumi Tabata. He analyzed and compared the effects of moderate-intensity endurance training and high-intensity intermittent training on performance, specifically VO2max and anaerobic capacity. He found that 60 minutes a day of moderate intensity work performed 5 days a week over a 6 week period did increase VO2max on an average of 5 mL/(kg*min) but had no significant effect on anaerobic capacity. However, those who performed high-intensity interval work 5 days a week over a 6 week period experienced an average VO2max increase of 7 mL/(kg*min) and a 28% increase in their anaerobic capacity.

How do you suppose the high-intensity work sessions were structured? Does 8 sets of 20 seconds of all out work followed by a 10 second rest sound familiar? Thus the Tabata interval was born and has since wreaked havoc on CrossFitters near and far. The intensity at which we perform our workouts is key to achieving positive results. So next time we do our Tabata Squats, suck it up and know that your aerobic and anaerobic energy systems are being challenged more in those 8 minutes than if you were to go for an hour run. Crazy, huh?
