Re: athletes, fast-twitch muscle & CFS

[Guest guest]

Hi, Ken, , & all,

With so much discussion on aerobic capacity, fast vs. slow-twitch muscles,

etc. I thought I should put in a few words.

I also was more of an endurance type, but hated running so no X-country.

Also, slight build, lower muscle mass, had the capacity to hold my breath

for long periods, and prefer non-continuous sports.

When I was tested for mito funtion over the summer, the researcher noted

that I have the muscle makeup of an Olympic-class sprinter - almost all

slow-twitch (anaerobic) with little slow-twitch (aerobic) even after enough

exercise that the aerobic set should have kicked in. He saw this thru pH

change in the muscle (went acid within a second of starting exercise) and

phosphocreatine levels.
