Christian,
given the goal is to build as much muscle as possible. (as its nearly always…)
given S/O isnt a total newbie, has some regeneration abilitys and uses good form on the exercises.
And if Im right about that:
- The excentric movement causes the most muscle damage.
- S/O is the strongest in lowering the weight(excentric again).
- S/O can use the SSC to move some of the weight(especially at sticking points;i.e. the bottom of the benchpress)
- the SSC is decreased for about 60% when taking 1sec. of a stop
Then what do you think about these two possible reps/tempos?
What whould you prefer?
(Just an example, as exercises isnt that much important right now)
A1
Acromial Bench FG 4x6-8 , 30X0 ; 60’
A2
Chinup, close 4x6-8 , 30X1 ; 60’
Pro:
more powerdevelopment (cause of SSC) ?
you go to momentary muscle failure each time
con:
you use lower weight?
SSC makes it easier for the muscles?
OR
A1
Acromial Bench FG 4x4 , 51X0 ; 60’
A2
Chinup, close 4x4 , 51X1 ; 60’
Pro:
slower excentric does more muscle tissue damage (bigger growth response)?
cause you spend most time in the strongest direction you can use more weight?
you dont have that much a SSC, and are so using more of your “real strength”?
con:
lesser power development (but wich mustnt equal lesser force development,right?)?
anything else thats con?
I hope you can see what I meant. ![]()
What do you think?
Thanks beforehand.[/quote]
Yes more damage is caused by the eccentric portion than during the concentric portion. But the turnaround point in a SSC exercise (point where you sharply stop the downward movement to shift into lifting phase) is probably where the potential for micro-trauma is the greatest.
Furthermore, just because the eccentric phase is where most of the damage occurs (the turnaround point being included in the eccentric phase) it doesn’t necessarily means that slow eccentrics will be more effective in causing micro-trauma.
The eccentric phase also respond to overload, so a slow eccentric (let’s say 4-5 seconds) with less weight might not be more effectice at causing micro-trauma than a normal one (2 seconds or so) performed with more weight.
To cause micro-trauma the eccentric must be performed in a state where muscle tension is as high as possible. And muscle tension is proportional to force production, so if doing the eccentric slowly means that you must use less weight, then it is probably not worth it.
That having been said, I still recommend being in control of the weight, just not to lower it slowly on purpose, unless one is using special techniques where the eccentric load is very high.
Oh yeah, I don’t like giving tempo prescriptions. It’s just plain dumb to assume that during a grueling set one will be able to maintain the prescribed tempo. Furthermore if one is focusing on counting the tempo or following it, there is no way that the lifting performance will be optimal.
Tempo prescription is one of those things that coaches use to seem more important than they really are.
Yeah, in the past I used them, before I knew better.
