Wiggins has 11 months to lose a combination of upper body muscle and fat after the 2008 Olympics. He loses muscle but once he gets down to 71kg and 4% bf about 1 week before the start of the 2009 TdF, he really really does NOT want to lose any more muscle.the big ring said:I'm confused
Brad says he was only burning fat, no muscle.
BC coach only mentions losing muscle mass (NOT just upper body).
So which is it?
Bravo! This is a much more complex question and not stupid at all. Nobody knows the answer because asaik Wiggins didn't have muscle biopsies to check these things. Maybe he lost no leg muscle mass? Maybe he lost a little bit but not enough to lose power? Maybe he did lose power over 4mins and so his best 4km track times were lower, but he improved his average power over longer distances by increasing his training volume (something which is known to stimulate mitochondrial biogenesis and capillarisation). I've done "power profile" testing on athletes before and you can see shifts in the profile (ie: shape of the hyperbolic relationship between power and time) over the course of a single season depending on what training phase you are in.Brad is a classic ectomorph, and would not have that much upper body to lose. IP starts equate to very little of the IP race and upper body strength is nowhere near as important as core strength in developing an effective start.
Krebs cycle - your name suggests you can tell us. IF Brad did lose muscle mass in his legs, does he also lose mitochondria? If he does lose mitochondria, does his absolute VO2max reduce proportionately (whilst relative VO2max may increase)?
The reality is that any changes that did occur, happened slowly and gradually. There simply is no evidence of a sudden and large increase in his PPO which is what happens when you start a blood doping program. There is evidence that he lost weight and thus his w/kg went up which accounts for his improved hill climbing ability. So there is good chance his relative VO2max went up too. Big deal. That has been done by 1000s of cyclists from recreational to pro level for decades upon decades.
There are plenty of studies in the literature which show that mitochondrial density increases with endurance training and also altitude training. Here are a couple of recent publication to get you started....

If you guys are so keen to learn about how it is possible for Bradley Wiggins to have transferred from track to road and you want to know his VO2max numbers in relative units, then why don't you just contact GB cycling and ask them directly?

If you don't want to learn anything and are just trying to troll me, then how about you gtfo?
