What the Evidence Actually Shows
Across 10 randomized trials, HBOT significantly accelerated recovery from exercise-induced muscle injury (95% CI: -76.19 to -33.11; p<0.0001). But here is the catch: objective damage markers improve while athletes often report no difference in how they feel. The evidence for sports HBOT is more nuanced than the celebrity endorsements suggest.
The 2025 Meta-Analysis: Best Available Summary
The most comprehensive pooled evidence comes from a 2025 systematic review and meta-analysis by Luo and colleagues, published in Archives of Physical Medicine and Rehabilitation.1 The review pooled 10 RCTs with 299 subjects.
“HBOT significantly accelerated recovery from exercise-induced muscle injury (95% CI: -76.19 to -33.11; p<0.0001) across 10 randomized trials. However, there was no significant effect on muscle soreness and no enhancement of strength or endurance performance.”
Luo et al., Archives of Physical Medicine and Rehabilitation, 2025
This is the clearest summary of where the evidence stands: HBOT helps structural muscle recovery (reduced CK, myoglobin, transaminases) but does not reduce soreness or improve athletic performance metrics.
The Cochrane Review: The Skeptical Baseline
The 2005 Cochrane review by Bennett and colleagues analyzed 9 trials with 219 participants examining HBOT for delayed onset muscle soreness (DOMS) and closed soft tissue injuries.3 Conclusions were unfavorable: insufficient evidence to establish HBOT’s effectiveness, and HBOT may actually increase interim pain at 48-72 hours when started immediately after eccentric exercise (mean difference 0.88 on a 0-10 scale, p=0.03).
This finding has been widely cited for 20 years and remains relevant: HBOT does not reliably reduce muscle soreness and may temporarily worsen it.
The Best Positive Study: Real Injuries vs Lab-Induced DOMS
The key distinction in the literature is between lab-induced DOMS (where HBOT mostly fails to help) and actual sports injuries (where results are more positive). A 2019 RCT by Chen and colleagues enrolled 41 athletes with real exercise-related muscular injuries.5 After 10 HBOT sessions, the treatment group showed significant reductions in:
- Creatine phosphokinase (CK) — a marker of muscle damage
- Glutamic oxaloacetate transaminase (GOT)
- Myoglobin
- Pain intensity and interference
Benefits lasted at least 2 weeks post-treatment. This is one of the stronger positive studies specifically because it enrolled athletes with actual injuries rather than artificially induced DOMS.
“The disconnect is real: HBOT consistently reduces objective muscle damage markers like creatine kinase and myoglobin, but this doesn’t reliably translate to feeling less sore or performing better. Biomarkers and subjective experience don’t always align.”

Pro Sports Adoption
Multiple professional athletes are reported to use HBOT chambers for recovery, including well-known names across the NFL, NBA, Premier League, and Olympic sports. Teams in several leagues reportedly operate chambers at training facilities. However, published clinical data from professional sports contexts is essentially nonexistent. The adoption is driven by anecdotal reports and accessibility, not peer-reviewed evidence from elite athletes.
Clinical Data by Application Area
Muscle Recovery
Published studies on HBOT for exercise-induced muscle damage show:
- Reduced objective muscle damage markers (CK, GOT, myoglobin) in studies using actual athletic injuries5
- No consistent effect on DOMS pain in lab-induced soreness models3
- Possible worsening of short-term soreness at 48-72 hours in some protocols3
Concussion Recovery
TBI and concussion data shows cognitive improvements in post-concussion syndrome patients. Sports medicine practitioners increasingly incorporate HBOT into return-to-play protocols, though evidence from sports-specific concussion populations is limited.
Bone and Soft Tissue
Animal models show improved healing after soft tissue injury. Human data for bone fracture and ligament healing in sports contexts is limited and mostly case series. A 2025 narrative review by Johnson-Arbor in Undersea and Hyperbaric Medicine4 concluded there is “limited evidence to support the use of HBO2 to enhance recovery in athletes” and raised safety concerns about non-medical mild chambers.
Recovery Protocols Used in Sports
| Application | Typical Pressure | Sessions | Evidence Level |
|---|---|---|---|
| Actual sports injuries | 1.5-2.0 ATA | 10+ | Limited positive RCT data |
| Lab-induced DOMS | 2.0-2.5 ATA | 3-7 | Mostly null or negative |
| Post-game recovery | 1.3-1.5 ATA | As needed | No controlled data |
| Concussion protocol | 1.5-2.0 ATA | 20-40 | Limited positive data, off-label |
Can You Use HBOT at Home?
Many athletes have purchased home chambers for convenience:
- Soft chambers ($4,500-$12,000): Suitable at 1.3 ATA for routine post-training use. Popular among amateur athletes. No evidence specifically for this pressure and application.
- Home hard chambers ($25,000-$43,000): Deliver clinical pressures. Used by professional athletes who want sessions matching clinical protocols.
The Johnson-Arbor 2025 review noted safety concerns about mild HBOT chambers that were designed for altitude sickness, not sports recovery, and are sometimes marketed for athletic use without appropriate regulatory oversight.
WADA Status
Hyperbaric oxygen therapy is not on the World Anti-Doping Agency prohibited list. Competitive athletes can use HBOT without anti-doping concerns.
