Everyone is making a big deal about the posterior chain development, which I'm not discounting, but that's not only what makes Nordic ham curls so awesome: They develop the calves and hamstrings through knee-flexion/extension as opposed to only hip extension, which improves stability of the knee and reduces the risk of injury.
I've written extensively about
the importance of our S&C properly implementing hamstring work, particularly knee-flexion hamstring development.
They are fluky, which is why we differentiate between contact injuries and non-contact injuries. Not much you can do when someone dives at your knee or wraps you up awkwardly, but frequent non-contact ACL tears can be attributed to the overall training goals of the S&C program.
I agree with this, even having never seen his programming. New staff comes in and everyone wants to **** on the old S&C coach - Feeley was well-educated in this field and I would put down good money with odds that he was doing proper hamstring work with the team. Injuries dropped way down from when Felder was here.
Have you been reading my posts?! I've only been saying this for like 8 years.
This is the answer and I'm betting you either work in the field or a closely-allied one like athletic training or physical therapy.
I want to be explicitly clear that I respect you as a poster and I don't want anything I say to come off combatively or disrespectfully, only that I disagree with you philosophically. At least I
think I do - I read your post a couple of times and maybe I'm misinterpreting what you're saying, so just correct me if I'm agreeing with you lol.
Nordic hamstring curls are awesome but their primary purpose is not power development, it's through developing the hamstrings eccentrically to make them a stronger antagonist to the quads, improving knee stability and yes, aiding in stride frequency. When you do them you're not focusing on concentric power, you're focusing on slowly elongating the hamstring which causes the most damage and therefore the most hypertrophy. They're essentially negatives to failure.
The part where I'm not sure where you're coming from is in regarding your thoughts on ONLY the load being the most important factor in S&C - I'm not sure if you're mocking other coaches (I agree!) or if you're saying that's what you believe personally, I'll just add in that this has been a debate for some time now but it's pretty evident that high-threshold motor units which are responsible for producing high amounts of force can be trained either through heavy load (strength work) or through speed, but all things being equal, neural rehearsal of a movement and specificity will always be superior to absolute load in practice.
But to your point, yes, speed and power are the name of the game.
