you state the stretch portion more important consider this
Consider: The stretch portion of an exercise may be the most productive however what is more important?
(a) The level of load at the point?
(b) The amount of time spent working in this zone?
© A combination of both, and if so what combination (50/50, 70/30)?
(d) Working with high load in this zone when fresh?
(e) Working in this zone when already pre fatigued in other zones?
If you strated in the fully contracted position then would you be working harder in a way than had you started there fresh (and vice versa ;^).compare the stretch portion of a chin up, dip or bottom of a squat with, a pulldown, bench press or leg extension. In the first 3 you may find it best to go from stretch to fully contracted as the stretch is extreme. With the second 3 the other way around may be better as the stretch isn't dramatically harder than the fully contracted position. As well, all this will depend on equiptment choice.
Well, technically, if you read my guidelines for BLOWreps, I noted you could do it in literally any order you wanted.
That said, by default, I'd invest the most energy into what would theoretically give you the most payback, i.e. the stretch portion.
I don't buy into the pre fatigue crap other than as a change of pace.
Phrased differently, if it was your intention to grow, would you rather:
* Pre-fatigue yourself with a bunch of high rep sets before doing a top, heavy set of squats
* Warmup, do a top heavy set, and then maybe do some backoff high rep sets?
I would say the latter choice is far more logical. The key to muscle growth = progressive tension overload. All else constant, it makes the most sense to be as fresh as possible to that which is giving you the most returns.
By this same logic, why would you want to pre fatigue yourself before going into the stretch portion? All you're really doing is compromising the amount of load you can use for the possible benefit of some extra metabolic stress. Call me a dinosaur, but I don't buy that line of thinking.
Not that there's anything WRONG with starting in the "pump" half or any other position (and as I vaguely alluded to, there's even research showing that it's possible that, for some muscles, a more contracted position could actually be better for hypertrophy), just that, as a rule of thumb, it makes more sense to me to start in the stretch half to do so as fresh as possible and with as much load as possible.
