FT muscle fibre expression

That's an interesting observation on the " potato-couch fibers " , and

seems to be confirmed by results obtained with electrical muscle stimulation

(EMS) training.

Research on exercise performed with EMS, shows that so-called maximum strength

EMS programs convert both IIx and I type fibers into IIa.

Giovanni,

I agree it is interesting. The studies that have been done so far on

intracellular signaling might also help explain why. Basically any time the cell

is stressed regularly with metabolic activity, things tend to shift from fast to

slow. This seems to be true even when training involves explosive activities.

The good news: a proper taper allows FT adaptations to manifest. Hopefully some

research groups will study various kinds of fatigue management tactics to see

what's best for mitigating the shift in the first place. In general, it probably

makes sense to use a cluster/rest pause strategy when training advanced

athletes.

The big problem with those couch potato fibers is that they don't do much of

anything - and may be most susceptible to sarcopenia down the road.
