Hyperbaric oxygen therapy has become a more and more popular choice of therapy among injured rugby and football players.

The latest sportsman being England cricketer Simon Jones. He has been facing a week of treatment in a sealed hyperbaric oxygen chamber designed to accelerate the recovery of his right ankle problem he sustained during this week’s fourth Test win at Trent Bridge.

Dr Peter Gregory, ECB’s chief medical officer, described the treatment device to The Times as a “sealed pressure container” of the type used by divers who have surfaced too quickly. It will be used to force oxygen into the fast bowler’s body in order to hasten his recovery from damage to the soft tissue at the front of his right ankle.

Hyperbaric oxygen treatment boosts white blood cell activity in damaged parts of the body, controlling infections as well as tends to constrict blood vessels and decrease the amount of blood pumped by the heart. The therapy diminishes blood flow to an injured region, helping to reduce pressure and swelling.
