All--

What's the difference, specifically regarding the hamstrings??
I thought that by leg curling really heavy (face down, on Nautilus type
machine), I'd be killed by DOMS the next day. Yet this has never happened.

But in squatting, even cleans/jerks, even *weed-pulling*, my hamstrings are
*killed*--doms for days.

I woulda thought that leg curling would kill the hams, while squats etc.
would get mebbe the ass/lower back.
Any idears?

Just one: That leg curling by X pounds wouldn't create the DOMS
response that squatting by 3X pounds would. Yes?

I mean which would cause DOMS more noticeably - bent rows with several
plates or dumbbell curls with the pink vinyl-covered one-pounders?

In the hamstrings? Not for me. Squats and leg presses don't
sufficiently tax my hamstrings, which is why I train hams on a
different day to quads. But then, I'm not normal.

So what does a leg curl do, then?

Both work the hamstrings. Hamstrings are two-joint "bi-articulate"
muscles, with attachments above the hip joint and below the knee.
They both flex the knee and extend the hip. Leg curls and any hip
extension exercise will both work the hams. Squats work a lot more
muscle groups, though.

No, because there is only a 25% load transfer (or whatever) to the hams when
squatting.

The hamstrings travel over two sets of joints - the knees and the hips.
They are somewhat unusual in that respect. They are prime movers in hip
extension, which is often not realized. So during the dynamic hip
extension of cleans and jerks they are really used quite heavily. Leg
curls, OTOH, only work them during the knee flexion movement. Unless you
are a bodybuilder you could probably throw out the leg curls machine and
just do cleans.

You proabably aren't squatting ass-to-the-grass either, are you?

If you were your hamstrings would be taxed. I mean going heavy and down
to where your hamstrings touch your calves.

Most people I know who say squats don't work hamstrings are doing
partial squats.

Nautilus machine isolates knee flexion - very little hip extension. In
terms of the muscle 3 of the 4 segments could be thought of being worked
in a partial movement.

Another consideration is that eccentric contractions appear to cause
more soreness than concentric contractions. Which would explain why
weeding (okay - it is a static contraction, but same idea) makes the
hamstrings sore.

For me - sprinting really makes 'em sore.

I don't think it's so much "which end" as the complexity of the
movement. I suspect that a lot more motor units are recruited, and
firing frequency and patterns are higher and more complex, when
attempting to stabilize a heavy, complex movement like the back squat,
as opposed to an isolated single-joint movement like leg curls. By the
same token, you would probably find the same thing to be true when
comparing back squats to reverse hypers.

This, of course, is theory. I can't find any EMG studies that directly
support that theory.

Its the stretch at the hip joint...

P.S. just because you got more DOMS doesnt mean squats are more effective
for hamstrings then curls...

I get more DOMS in the hams from deadlifts depending on how I do them.
