I bet roczen is back for outdoors. The advances in ortho is quite astonishing. Heart and ortho are the biggest money makers. Therefore the advancement comes the quickest. Docs come up with new procedures or different tools it really pays off. (Capitalism is awesome for that regard) but, hyperbolic chambers are awesome as well and I guarantee you roczen is probably sitting in one of those a few times a week for 3-4 hours at a time.
Here's how it works:
"In a hyperbaric oxygen therapy chamber, the air pressure is increased to three times higher than normal air pressure. Under these conditions, your lungs can gather more oxygen than would be possible breathing pure oxygen at normal air pressure.
Your blood carries this oxygen throughout your body. This helps fight bacteria and stimulate the release of substances called growth factors and stem cells, which promote healing." -mayo clinic
I've seen numerous studies that blatantly show bone healing faster in the chamber than the placebo chamber. (An empty chamber that does nothing, the test subjects don't know if they're in a true chamber or a pseudo chamber) next time im at work I'll see if I can dig it up. It's really cool. Can't access this stuff without a subscription.
