Dr. Yoshiaki Sato invented KAATSU in 1966, but it took him decades of further discovery and fine-tuning both the usage protocols and equipment before he met Professor Naokata Ishii of the University of Tokyo, a renowned Japanese exercise physiologist.
Their work ultimately led to the first seminal paper on KAATSU called “Effects of resistance exercise combined with moderate vascular occlusion on muscular function in humans”, published in the Journal of Applied Physiology in 2000.
The paper concluded,
“Owning to its small mechanical stress and large effect in inducing muscular hypertrophy, the deliberate combinatino of low-intensity resistance exercise and moderate vascular occlusion is potentially useful for accelerating the recovery of muscular strength in patients and aged people.”
The paper explained,
“Among aged populations, weakening of muscles in the lower extremity gives rise to serious problems such as inability to stand up and lethal injuries associated with a fall. Postmenopausal older women are subjected to an additional risk of osteoporosis.”
Based on the practical applications of KAATSU over the last two decades and this basic information explained by Dr. Ishii and Dr. Sato in the 1990’s, the use of KAATSU can significantly grown among Baby Boomers since.
