Effects of sprint interval training on cardiorespiratory fitness while in a hyperbaric oxygen environment

‘Exercise training and HBO2 exposure stimulate mitochondrial biogenesis, increase capillary density, and induce adaptive antioxidant mechanisms’

49 Healthy long-term intermediate-altitude residents were randomized into 2 groups: one performing six sessions of a SIT regimen over two weeks in a hyperbaric chamber (1.4 ATA); the other performing under ambient pressure conditions (0.85 ATA)

The results of this study demonstrated an improvement of cardiorespiratory fitness in the hyperbaric group, reflected by a a significantly higher increase in peak work rate and VE. <view study>
