Thib,
When it comes to performing straight sets of a given number of reps with the same weight, you’d execute a few practice sets to get a feel for the working weight and then move on to the “work” sets. At any given load, you’d likely end up either coming out of the gate flying on the first few sets and then dropping off on the last few in you have a specific number of sets as a target or you’d leave something in the tank early on and the last set or two would be the only ones where you’d be pushing the envelope.
Is this largely why you believe in ramping? Each set improves CNS activation a bit more on the way up to an all-out set that recruits and fatigues as many MU’s as possible as opposed to either burning out quickly and finishing off with relatively ineffective (or at least less effective) sets or leaving some in the tank early on but not really deriving any noticeable increase in CNS activation over the course of those sets?
That is EXACTLY the purpose.
Each set has two effects that can change performance of the subsequent work…
-
Activation/potentiation: a set increase the working state of the CNS thus improving performance potential.
-
Fatigue (neural or muscular) which can decrease performance. The closest to your limit a set is, the more fatigue (neural) it will have.
Activation minus neural fatigue = CNS “firing level”
CNS “firing level” minus muscular fatigue = performance
Most people need 3 work sets to properly activate the nervous system (some will need up to 5… those with an inefficient CNS and others will only need 1… those with a cat-like CNS).
So you will reach your peak neural potential on the 4th, 5th or 6th set… THIS is where you should go balls out. Getting your best, most demanding set earlier than the 3rd set of an exercise will drastically reduce your results simply because your neural activation state is not optimal.
Now, you also want to avoid too much neural fatigue before that last, balls-to-the-wall set because it would impair performance.
Since going close to your limit reps with a given weight will create more neural fatigue, you want to gradually ramp up those sets.[/quote]
Thanks for this, as I am still learning alot about the CNS this answers some questions I had.
One quick question though, would the CNS react the same way if you ramped up to say 3 working sets ( by this I mean say set 1) 10 reps set 2) maybe 7 or 8 set 3) 5 or 6 or something like 3x5 with 85% of 1RM give or take some, these are just random sets and reps) vs one all out set?
Thanks in advance coach.
