Cns Vs Fast twitch fiber ratio

Which one do you think has much more impact on your speed? Lets put everything else aside.

At what level? 12.0? 11.0? 10.0?

oo good point i didn’t even noticed that.

what about 10.0?

Since fibre type is directed by innervation, there really shouldn’t be a difference should there?

Sorry Im new here but what does innervation mean?

The nature of the fibre is determined by the nerve that fires it.
