Nordic Hamstring Curls: Not a Fan

I can't believe P.T.'s/A.T.'s working with elite teams are still prescribing this exercise as a method of reducing hamstring strains & preventing ACL trauma. It's tunnel vision focusing on the sarcomeres of the four muscles themselves. What about improving neural drive? Isn't that part of strength & power output too? Who ever strained one with the leg posterior to the torso? There is no carry over what so ever of this exercise to upright function.
My opinion is the resurgance of this exercise has something to do with the resurgance of isokinetics in the literature. Trying to find an "on field" way to replicate it. I'm seeing a lot of "quad-to-hamstring strength ratio" and "bilateral discrepency" terminology that I heard back in the early 80's.
There's some talk of the pelvis' role in the injury process, but they feel the the hamstrings are influencing the pelvis, rather than the other way around, as I see it on the high school level.

Joe,
Can you throw up a picture to describe this exercise? I may be familiar with it but not the term. I think I know what your talking about but might have a different name for it.

Errybody thinking they gotta hit that "core" and "posterior chain" to make the athlete! When it it hard and it isolates and hurts (and came from some other country), it must be good!

I am strength coach who uses this exercises, and dont fully understand why you are saying this is not a good exercise.

Also, what do you use/recommend to use instead of this exercise?

Are you also against Glute/Ham Raises, Physioball Leg Curls, and Slide Board Leg Curls.

I am just want to better understand where you are coming from. Thanks.
