Bodybuilders grow five times faster in hypoxia gym
The air we breathe contains 21 percent oxygen. If bodybuilders train in a room where the oxygen concentration has been reduced to 16 percent, their muscles grow 4-6 times faster than normal, according to research by Akinobu Nishimura.
Hypoxia & resistance training
But Kaatsu training, if you don't know what you're doing, is not without risk. What's more, it looks as though healthy strength athletes benefit more from regular training than from Kaatsu training.
Nevertheless, the principle is interesting. You could, for example, train in a room with a lower oxygen concentration. This increases the body's anabolic response, according to a 2010 Japanese study. It's not clear from this study, however, whether bodybuilders gain more muscle mass in this way.
Study
Results
The maximal strength increased more in the hypoxia group than in the normoxia group.
Nishimura speculates that training in a reduced oxygen environment boosts the production of lactic acid. That causes your testes to make more testosterone and the pituitary to produce more growth hormone. The concentration of free radicals may increase in the muscle cells, and the cells may react to this by boosting the anabolic processes.
