I'll clarify a few things on cortisone in laymans terms for those interested.
For a short background; I hold a bachelor of sports science, bachelor of health sciences, master of osteopathy, master of strength and conditioning and am just about to finish medicine.
Cortisone is essentially a stress hormone that makes you feel AWESOME. Though it has many cool functions.
You know that feeling you get when you're up late and you just cant stay awake but about 1am you get a big second wind and manage to stay awake and productive? Thats cortisol, the bodies natural version of cortisone.
Prednisolone is another artificial form of the hormone, just a lot stronger in its action.
Cortisol is like a fight/flight hormone that acts over the course of hours instead of seconds like adrenaline. It causes your body to mobilise fat stores and turn them in to blood sugar. Among with a few other metabolic factors it makes you have high blood sugar available to burn for exercise.
Cortisol also makes the immune system slow down, same with bone deposition, tissue repair etc. It pretty much moves all bodily functions towards handling exercise/stress.
I have used prednisolone a couple of times before. I get rather bad eczema from some obscure food allergies. Therefore I use prednisolone about twice a year for 3 days when a bad attack hits.
From my own experience I can say that you can suddenly go and pump out a 6 hour ride and still do PBs on my favourite climb by the end. Normally I would be 2mins slower or so.
When you wake up the next day, you are entirely capable of hopping on the bike and pumping out another 6 hour ride with a PB at the end. No sore legs at all.
The recovery effects of cortisone could be down to their anti-inflamm effects, but it also helps your muscles load up with fuel easily (glycogen resynthesis: normally you struggle to do this after hard training).
The down sides:
- it can make you a bit agro, not like anabolics, more like being stressed and angry
- it suppresses the immune system. So if you take it for too long your immune system cracks the ****s with you (i think this is one of the major reasons for so called "overtraining") and you can contract something like human parvovirus like Greg Strock did.
- it slows down wound healing
- it seriously messes up your bone density in the long run
- if you are truely sick, ie lung infection, it tends to make you feel pretty horrible generally.
Cortisone is not the whole story to Froome. Although it could help explain the stupidly skinny physique and his ability to loose all of his arm musculature (even compared to Rasmussen).
Its not the 1% bull**** either. His bike fit and general ergonomics are terrible.
The magic to Froome is that his cardiac output is utterly nuts. I mean twice what would be expected from a highly elite athlete. What causes that? No idea, but I would love to find out.
What figures do you have regarding his cardiac output?
