What Researchers Did
Japanese researchers tested whether mild HBOT (1.3 ATA with 31% oxygen for 60 minutes) improved mood and physiological recovery after 60 minutes of high-intensity cycling in a randomised crossover study of 10 healthy male athletes.
What They Found
During the 20-40 minute recovery window, heart rates were significantly lower in the mild HBOT group. At 60 minutes post-exercise, fatigue-inertia, tension-anxiety, and overall mood disturbance scores all improved in the HBOT group but not the control group. Oxidative stress markers were unchanged.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This was a small study of 10 healthy young men; results may not generalize to female athletes, older athletes, or clinical patient populations.
