Athletes report lower levels of lactic acid build up with hyperbaric therapy, greater endurance and less muscle fatigue. The pressurised environment of the chamber assists with sports injuries due to swelling, dehydration and ischemia. Higher concentrations of oxygen in the blood at the cellular level allows healing to occur at a much faster rate.

Hyperbaric chamber oxygen therapy can decrease the amount of scar tissue, bruising and swelling visible after surgery and decreases post-operative inflammation and infection.
