What Researchers Did
Researchers conducted an RCT randomizing healthy adults to perform sprint interval training either in a hyperbaric oxygen environment or under ambient pressure conditions over two weeks to assess cardiorespiratory fitness changes.
What They Found
Of 58 randomised participants, 49 completed the study. Both the hyperbaric oxygen and ambient air groups showed an increase in peak oxygen consumption (V̇O2) by 8.1% and 7.1% respectively, but this difference was not statistically significant (p=0.50).
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study involved a relatively small sample size of healthy, intermediate-altitude residents over a short two-week period, which may limit generalizability.
