I love the master coaches who force us all to think critically…? Specially when it is counter to the CURRENT evidence we are indoctrinated into.
Is the Nordic the problem or is the hype about a panacea the issue?
Do hamstrings get hurt mostly due to lacking eccentric strength (an obvious factor) or poor timing and overloaded due to poor Co contractions (possibly).
@PfaffSC says “hamstring get hurt when they contract too early, too late or for too long”.
When ever we make one thing the main thing in prep or injury prevention, we are almost instigating Goodhearts law. It gives us a feeling of power and control to measure something and it improve. It gives us a feeling of control when the research says , this exercises fixes this issue.
What about when it doesn’t fix it?
When we create principles and heuristics and use them to make decisions I think we are much closer to high performance.
Do athletes need nordics or high intensity eccentrics? Should they be knee based, hip based , slow speed, fast speed or is a “total hip conditioning” a more holistic solution?
Where is the discussion going with the research so far?
Are nordics counter productive for some individuals?
Should we be listening to athlete feedback on dosage and density?
Is there an impact on coordination in running when hip vs knee based eccentric qualities improve ? Less strain on posture chain, Less variability in late swing phase, better pre activation of posterior chain and more economical running gate?
The surge in the use of Nordics as a hamstring injury preventative is alarming. Nordics are the cause of the disease, not part of the cure. They spread the disease, they don't vaccinate against it.
