What Researchers Did
Researchers combined results from 10 randomized controlled trials (299 subjects total) in a meta-analysis to determine whether HBOT reduces exercise-induced muscle injury and soreness in athletes and college students.
What They Found
HBOT significantly accelerated recovery from muscle injury (p<0.0001), with benefits seen at both higher and lower atmospheric pressures and at session lengths of 60 and 100 minutes. However, HBOT did not significantly reduce muscle soreness overall, though subgroup analysis showed soreness reduction with 100-minute sessions and pressures above 2.0 ATA.
What This Means for Canadian Patients
For Canadian athletes, sports medicine practitioners, or active individuals recovering from intense training, HBOT can measurably speed up recovery from muscle damage. However, it should not be expected to reliably eliminate post-workout soreness based on current evidence, and both session length and pressure affect outcomes.
Canadian Relevance
No direct Canadian connection identified. Sports and athletic recovery uses of HBOT are not OHIP-covered.
Study Limitations
Only 10 trials with 299 participants were available, the studies varied in how muscle injury was induced and measured, and most were conducted in non-elite athletic populations.
