But will a Plyo before an eccentric allow it to target more HTMU’s than normally would be the case? I don’t know. I don’t think there is any studies that have looked at that yet. But if I was to find out, I wouldn’t ask a guy who has no experience or formal training like you appear to be doing.

Regarding the plyo before an eccentric. not many people have expermented with this idea yet. By the extremely negative reaction here I dont belive that majority of people on T-Nation had heard of such a thing. So dont expect a lot of research.
in regards to 1RM’s, studies have been shown that depth jumps prior to 1RM attempts have increased the 1RM.
Acute effects of plyometric exercise on maximum squat performance in male athletes
"
ABSTRACT
This study examines the acute effects of plyometric exercise
on 1 repetition maximum (RM) squat performance in trained
male athletes. Twelve men (mean age SD: 20.5 1.4 years)
volunteered to participate in 3 testing sessions separated by
at least 6 days of rest.
During each testing session the 1RM
was assessed on back squat exercise. Before all 3 trials sub-
jects warmed up on a stationary cycle for 5 minutes and
performed static stretching. Subjects then performed 5 sub-
maximal sets of 1�??8 repetitions before attempting a 1RM lift.
Subjects rested for at least 4 minutes between 1RM trials.
During the first testing session (T1) subjects performed a
series of sets with increasing load until their 1RM was de-
termined. During the second and third testing sessions sub-
jects performed in counterbalanced order either 3 double-leg
tuck jumps (TJ) or 2 depth jumps (DJ) 30 seconds before each
1RM attempt.
The average 1RM lifts after T1 and testing
sessions with TJ or DJ were 139.6
29.3 kg, 140.5
25.6
kg, and 144.5
30.2 kg, respectively (T1
DJ; p
0.05).
These data suggest that DJ performed before 1RM testing
may enhance squat performance in trained male athletes.

verkhoshanksy’s application of the stimulation method is similar, but he first provides a tonic exercise (back squat), which then has an effect on a developing exercise (depth jump, single leg hops, jump squats, weighted jumps).
have any of you seen him use any variations, that utilize a ME lift as the developing exercise?
anyway, brief explanation of verkhoshanksy’s stim method:
-
to employ the hyper excitability of the CNS created by breif powerful muscular tension, to enhance the subsequent specific work, in order to develop explosive strength & the reactive ability of the neuro muscular apparatus.
-
any irritant which stimulates muscle activity, however short term, leaves traces in the nervous system. the trace phenomenon remains for some time after the stimulation has ceased. These traces can have a significant effect on the subsequent muscular activity; in particular, enhance the magnitude of this activity. For example,the preliminary isometric tension has a positive effect on the subsequent dynamic work. This effectiveness of this preliminary tension is up to 20% higher in comparison with the work conducted without preliminary isometric tension.

I think I was the someone else in your post. just for clarification, I was saying that the use of plyo to stimulate the HTMU’s for hypertrophy/structural gains (vs neural) has not been studied greatly.
in other words most research of the complex method revolves around studies which you posted, plyo + ME (heavy loading). Not plyo + RE - especially the use of very slow eccentrics (RJ’s suggested method) as the RE exercise.
Hope that clarifies my point
And regarding verko’s use of the stimulation method, I have not used them this way, but I do know of some people who have with positive results…
