First you say full ROM, then you redefine ROM as partials (90 degrees)?
That doesn't make a whole lot of sense..

Yeah, guess I define full ROM based upon the exercise. Some exercises such as biceps curls or pull ups have a greater functional ROM than others like chest press.

Suppose I'd base my "full ROMs" by whatever is functional, and safe. There are certain exercises that exercising the literal full ROM puts an excessive amount of forces on the target joints and do not offer adaptive for such risks. A guess a couple of examples would be leg extension/curls or triceps pulldowns, in which "locking out" the joints at the end of the "lift" part of the exercise places a great amount of strain on the joint. Hope that explanation makes a little more sense, but yeah, full ROM + some partials.

Do you have any data that suggests that this extra strain is actually dangeoraus? And locking out with iso triceps movements won't put that much strain on the elbow because you won't use a lot of weight. You'll probably have way more at the 90 degree elbow angle because then the lever arm is greater.

Now then you might say bench pressing, since bench pressing uses A LOT of weight, well, still, it doesn't have to be as high as a heavy triceps pressdowns (at midpoint), again, because of lever arms. When the triceps contracts it doesn't only extend the elbow, it also pulls the ulna into the humerus and because of the big lever arm the triceps will have to contract A LOT, thereby pulling the ulna into the humerus very hard.

It would make sense to do full ROM as possible, obviously so not to cause injury.

If you only to part motion, then your limiting the amount of motor units you recruit and therefore your strength and hypertrophy will be minimal.

Why will you recruit more MUs with more ROM? of course, if you do quarter squats with the same weight you do full squats then the quarter squats wouldn't be heavy and wouldn't need all the MUs, but what if you do a 5RM in each.. why is the full ROM more effective in recruiting MUs?
 
yeah they are recruited depending on how much force you need.. but there could be other things involved too.
 
I pretty much always do full ROM, but have been considering some partial movements to increase strength. I'm not sure I'd call it partials, but more full ROM with pauses at cretain points. From what I understand that recruits more MU's - does that make sense?
 
When I was answering the question, I kind of had a 90degree rom biceps curl vs 90+ biceps curl.

So using this as an example, not all the MU's would be used to their potential, as some would be favoured during certain degrees than others.

You'll have to look at a textbook, sorry i'm not sure :p
