In 1983-1985, Dr. Tabata visited Oslo, Norway as a visiting scientist during his PhD course, and learned how to measure anaerobic energy release from late L Hermansen, PhD who first defined maximal oxygen deficit as measure of anaerobic capacity. He earned his PhD from University of Tokyo, Japan. As a post-doc, he studied under late John O. Holloszy, a legendary scientist at Washington University (St Louis, USA), where Dr. Tabata learned biochemical adaptations to exercise training in rats. In 1996, he first published a paper regarding Tabata training. Since then, he has been studying effects of exercise, especially high intensity intermittent training (HIIT) on sport performance and health using both human and experimental animals. Dr. Tabata has published 138 original papers including 125 papers written in English. He's a member of Japan Academy of Science and was first dean of the faculty of Sport and Health Science at Ritsumeikan University for 6 years.
