Let’s say that my FTP went from 100 to 150. What happened?
Do I have more mitochondria? More muscle mass? VO2 max increase? All the above?
@chad this would be a GREAT podcast discussion. Parts of the changes have been addressed at different times – increased mitochondria, blood plasma volume, blood flow to muscles; fiber strength increases; etc. But nothing laid out overall.
Interesting , I’d like to know as well.
Yes, good question…no idea!
This is a great podcast series if you are interested in learning more about human physiology and training effects.
6 part podcast, averaging about 1:15 each.
Too many insights to summarize here, but I got the most out of the description of the three energy systems, creatine phosphate, glycolysis and aerobic. And how the different fuel sources - creatine phosphate, glycogen/blood glucose (and derivatives pyruvate + lactate), and fat are used by each.

Maybe the most important change of all:

I knew it! thanks for the links
My WAG:
Increased O2 carrying capacity.
Increased stroke volume.
Increased ability of muscles to uptake O2.
I see a reference to changes with blood plasma volume. Was this discussed is a podcast?
Thank you.
@AujujuSauce, Looks like you have to be a member of University of Nebraska or another campus to get access to these articles, since you need a login
Some of the public libraries have access to this database. Ask yours. In Iowa I think you have to use the State Library log-in to get into medpub. No cost to residents – just have to know to ask.
