Some info to help with what I've been saying:

Adaptations to Endurance Training

• Little/no increase in CSA of all fiber types

• Fiber type shift

– Increase % of Type I and Type I/IIa hybrid fibers

– Decrease % of Type IIx fibers (fast - days)

– Decrease % of Type IIa fibers (slow – years)

• Increase in muscle oxidative capacity

• Increase in mitochondrial density

• Increase capillary to fiber ratio

• No increase in glycolytic enzymes

– Possible increase in very intense training

• Increase in fatty acid oxidation, increase intramuscular lipid stores

• These changes lead to a delay in the onset of metabolic acidosis, increased resistance to fatigue, increased VO2max


Adaptations to Resistance Training

• Increase in muscle CSA (hypertrophy) in all fiber types – including Type I (usually)

– May be increase in fiber number, but size is most change

– Increase in number of nuclei per fiber (maintain nuclear domain size)

– Satellite cell proliferation

– Increase in muscle power

• Fiber type shift

– Decrease in % Type I fibers

– Increase in % Type IIa fibers

– Decrease in % Type IIx fibers

• Metabolic changes

– Decreased mitochondrial density, but due to hypertrophy, not fewer mitochondria per fiber

– No change in capillary:fiber ratio (but may be decrease in capillary density)

– No change in VO2max

If you act sanctimonious I will just list out your logical fallacies until you get pissed off and spew blasphemous remarks.
