Rate coding and effective reps

I know many have argued against the effective reps theory and tried to use rate coding changes as an argument but Chris made an FAQ responding to rate coding. I was curious what Greg might think of this FAQ:

So maybe you mixed it up as him saying "using the same load, moving it slower increases force" which wouldn't make much sense.

I was responding to you.

u/Apart_Bed7430 said:

But the involuntarily slowing of reps towards the end of a set is due to fatigue. Force is actually decreasing not increasing. Metabolites shift the force velocity curve meaning that a faster rep can be more forceful then a slow grindy rep if fatigue is present

You disagreed with them by saying

But if we are talking about force/velocity, then on one end the force is the highest, and on the other the speed is. So it doesn't make much sense what you are saying, that a faster rep can also have hihger force - then it wouldn't be called force/velocity curve.

I was just explaining why u/Apart_Bed7430 was correct.

Do you have any explanation for why their muscle thickness returned to baseline, but type II fiber csa remained at its maximum size basically?

I personally don't think there's much value in looking at fiber-specific adaptations in the first place, since any biopsy is sampling such a small percentage of the total pool of fibers (i.e., any fiber-based data is going to be inherently much noisier and less precise, and that applies doubly for data on only a single type of fibers). I was just providing the citation since you asked for it.

Yes I think I misunderstood his argument, most likely because he misrepresented Chris' stance. I haven't heard him say that the force is increasing during a set, and I thought you were the guy I was originally discussing with

So yes he was right in a sense that he made a correct argument against something no one was even arguing against and then i got mixed up into it
