What Researchers Did
Researchers investigated the effect of hyperbaric oxygen therapy (HBO) on exercise-induced muscle injury in 21 college-aged male volunteers, assigning them to control, immediate HBO, or delayed HBO groups.
What They Found
All groups showed significant increases in forearm flexor cross-sectional area (CSA) by 21% at 2 days and 18% at 7 days post-injury. However, there were no significant differences in CSA between the control, immediate HBO, and delayed HBO groups (P = 0.438).
What This Means for Canadian Patients
Canadian patients experiencing exercise-induced muscle injury may not find significant benefit from hyperbaric oxygen therapy for improving muscle recovery. Current evidence suggests that HBO does not significantly reduce muscle swelling or improve recovery compared to standard care.
Canadian Relevance
There is no direct Canadian connection to this study.
Study Limitations
The study's findings are limited by its small sample size of 21 college-aged male volunteers and specific injury model.
