Act as if you don't care. I find it funny how you disagree with what I said yet you post a bunch of papers that point to hypertrophy caused by muscular contraction.
:yawn:
Alright- this has gotten old as hell by page 3... :rofl:
Where is the study showing positive vs negative movements??? (ITs to early in the am for me to go digging through everything)..
Anyways, Your using the logic that after every negative, there isa positive (on contraction) back to the top of the movement.
I challenge you to look for research based on static holds. hell, eliminate the movement.
Muscle growth, is based on stress against muscle fibers. contractions, negatives, holds,.. does not matter. You will grow as long as your body needs to adapt to that stress.
Doing negatives causes stress becasue A) you can use more weight. B) it goes against the normal movement of the muscle.
It is possible to never use a concentric motion and train with static holds and looooooooong negatives.
Your CNS will become taxed for many and any reason in which it fires off too many signals for contraction/static or negatives.
If you REALLY want to bring cns burn down, then do isolation movements.
Studies will show you can lift more weight with one body part then by doing the same excercise with both (like bd rows)
...of course, you may be using more weight this way which would make up the balence, but thats beside the point.
CNS burnout has happened to be my biggest problem the past few years it seems.
