This begs the question -- is the shortening rate change a function of
recruitment changes or an increase in, as Seiler puts it;
"identifiable proteins and structural characteristics that confer high
fatigue resistance (endurance).
If there is a slowing of shortening rate as a function of structural
characteristics then a prudent exercise protocol for strength/power athletes limiting
conversions would seem to be in order. If there is an increase in fatigue
resistance yet max shortening can be maintained via peak force/time training then
the conversion to type IIa would have the best of all worlds, i.e., peak
force, rate there of and increased endurance?
