Pro athletes have made HBOT a public story. NFL stars, NBA players, and UFC champions have shown off home chambers and credited HBOT for recovery and longevity.
This guide is the celebrity-focused companion to our athletic recovery analysis. It covers who in pro sports uses HBOT, what they claim, and what the data shows.
We will cover the major NFL and NBA users, the brain injury angle, the trials, and how home gym athletes should think about the celebrity story.
The headline NFL users
Several NFL figures have made HBOT use public.
Joe Namath credited HBOT for recovery from chronic post-concussion symptoms. The Hall of Fame quarterback completed 120 sessions at Jupiter Medical Center in Florida (Stoller, AANR Case Report 2017). The case study was widely covered but is one case, not a trial.
Terrell Owens, Tim Tebow, and Hines Ward have shown HBOT in personal recovery videos. Several active NFL teams have HBOT chambers in their training facilities — including the Dallas Cowboys, San Francisco 49ers, and Pittsburgh Steelers.
The most visible NFL HBOT user is not a player but a team owner. Several owners and coaches have invested in HBOT for personal use and for team facilities.
NBA and other pro sports
NBA. LeBron has used HBOT for recovery and reportedly owns a chamber at home (ESPN profile 2024). His HBOT use is part of a broader recovery stack with cold plunge and pressure compression.
UFC and soccer. Champions like Cristiano Ronaldo and many UFC fighters have publicly used HBOT for injury recovery. The MMA training community has adopted HBOT widely, and chamber sellers report strong demand from fighters between bouts.
MLB. A handful of major league pitchers have used HBOT for elbow and shoulder rehab. The pattern is more research-protocol than personal chamber, but a few stars own home units.
Tennis. Novak Djokovic has discussed HBOT for recovery after long matches. Several tour players use HBOT during major tournaments.
The chambers pro athletes use
A practical breakdown. Most home athlete chambers are soft-shell or hybrid units running at 1.3 to 1.5 ATA (CDC HBOT safety guide 2024). The OxyHealth Vitaeris 320 and similar mild-HBOT chambers are the most common home setups.
Some athletes use harder chambers (1.5 to 2.0 ATA) at clinic sites. The most common pro installations come from Sechrist or Perry Baromedical.
The pressure difference matters. A 1.3 ATA home chamber delivers a different therapeutic dose than a 2.0 ATA hard-shell clinic chamber. Most pro athlete use is in the lower 1.3 to 1.5 ATA range — closer to the mild-HBOT wellness tier than hospital medical HBOT.

What pro athletes claim HBOT does
The claims cluster around four areas.
Faster muscle recovery between games. Athletes report less soreness and shorter recovery windows after HBOT.
Concussion and head injury recovery. The Joe Namath case is the most cited example. Several players have credited HBOT for cognitive gains after concussion history.
Joint and soft-tissue rehab. Athletes recovering from surgery or chronic injury use HBOT to aid healing.
Longevity and career length. Older athletes credit HBOT for staying competitive past typical retirement age.
Each of these claims has a plausible biology basis. The trial data in athletes is much weaker than the celebrity story suggests.
What the trials actually show
A research summary. The athletic recovery HBOT trials are mostly small, short, and focused on markers rather than performance.
A 2019 meta-analysis (Branco et al., Sports Medicine 2019) of HBOT for exercise recovery covered 11 trials. The conclusion: small reductions in muscle soreness, no clear effect on performance.
A 2020 systematic review (Rothschild et al., J Strength Cond Res 2020) on HBOT and performance reached similar conclusions. The reviewers noted small samples and a lack of large, well-controlled trials.
For concussion specifically, the data is mixed. The military TBI trials in our TBI review failed to show clear HBOT-over-sham benefit. Civilian concussion trials are small with similar issues.
The placebo and expectation problem
Athletic recovery is prone to placebo and expectation effects. Athletes who believe a recovery tool works often perform better, sleep better, and feel less sore.
The line between body and mind effects is hard to draw in sports outcomes. Subjective measures like perceived recovery and soreness ratings often improve with HBOT. Hard measures like power output and sprint times show smaller and less consistent effects.
This does not mean HBOT does nothing. It means the celebrity stories cannot tell apart a real body effect and a strong expectation effect. Both are real, but only one transfers reliably to home gym athletes.
Should recreational athletes use HBOT
A practical question. The honest answer: probably not at current evidence levels and current pricing.
A 40-session course at a wellness clinic runs $4,000 to $12,000. The trial-evidence support for athletic recovery is modest. The placebo effect is real but expensive at that price.
If you do try HBOT for athletic recovery, treat it as experimental. Use objective performance measures — sprint times, lift PRs — at baseline and after the protocol. Re-evaluate at session 10 to 15 and do not commit to long protocols on celebrity testimony.

The concussion question
A particularly hard area. Athletes — especially in football and combat sports — with concussion history are highly motivated to try HBOT. The 1990s case studies have fueled this.
The published RCTs on HBOT for brain injury do not consistently show HBOT-over-sham benefit. The Cifu, HOPPS, and BIMA trials all found large symptom gains in both arms, with no clear difference between groups.
The case studies and uncontrolled trials of HBOT for chronic post-concussion symptoms are more positive. This is the methods gap: uncontrolled improvement is the rule in TBI rehab, no matter what therapy is used.
If you have post-concussion symptoms and are considering HBOT, see a sports neurologist or TBI specialist before committing to a long protocol. The intervention has a plausible mechanism but weak controlled-trial support.
The chamber-fire and safety concern
Pro athletes with home HBOT chambers face the same safety risks as anyone else. The FDA letter to providers 2014 covered reported fire incidents in HBOT chambers.
Home chambers are prone to fire risk because they lack the operator training and safety steps of UHMS-accredited clinics. Lithium batteries, oils, and synthetic fabrics inside chambers can ignite at high oxygen pressures.
If you are pursuing HBOT, use a UHMS-accredited clinic when you can. Home chambers should be run only with full vendor training and strict safety steps.
Bottom line
Pro athletes have made HBOT visible. The trial evidence behind the visibility is much weaker than the celebrity narrative.
For pro athletes with elite resources and time, HBOT is a low-risk experiment to add to a recovery stack. For recreational athletes at current pricing and evidence levels, the math is harder to justify.
If you try HBOT for athletic recovery, treat it as experimental, use objective measures, and set a budget. Do not assume the celebrity-endorsement pattern generalizes to your situation.

Frequently asked questions
Which NFL players have used HBOT publicly?
The most prominent retired user is the Hall of Fame quarterback who completed 120 sessions. Several active and retired players — Terrell Owens, Tim Tebow, Hines Ward — have used HBOT. Several NFL teams have chambers in training facilities.
Does LeBron James own an HBOT chamber?
Yes, LeBron has publicly used HBOT as part of his recovery regimen and reportedly owns a chamber at his home. The chamber appears in several social media posts.
What pressure do pro athlete chambers use?
Most home athlete chambers use 1.3 to 1.5 ATA — closer to mild HBOT than hospital medical HBOT. Some clinic chambers run at 1.5 to 2.0 ATA. Pressure varies widely across the athlete user base.
Does HBOT actually speed up recovery in athletes?
The trial evidence is mixed. Meta-analyses show small reductions in muscle soreness but no clear performance gains. Most reported benefits come from celebrity testimonials, not controlled trials.
Is HBOT safe for athletes to use at home?
Home HBOT carries fire risk because home chambers lack clinic safety protocols. The FDA has documented fire incidents in HBOT chambers. Home use should only proceed with full vendor training and strict safety steps.
Medical disclaimer: This article is informational and does not constitute medical advice. HBOT carries real risks including ear injury, oxygen-related harm, and chamber fire. The FDA has cleared HBOT for 13 specific uses; athletic recovery is not on that list. Discuss any HBOT plan with a sports medicine specialist or hyperbaric doctor before starting.
