101Pro. Good thought. But with some risk. Turning the leg out into external rotation can make the hip and groin area more vulnerable in that you had better have enough iso and eccentric strength of the anterior muscles that let the external rotation occur. Meaning, the glutes and external hip intrinsic myos will shorten to generate the turn out of the leg/hip/foot but the muscles on the front and groin have to be able to lengthen under load to allow for the rotation to occur. Muscle quite often can be weak in the eccentric phase (somewhere, i have to find the reference, i recall some research saying that a muscle has to be 3x strong eccentric compared to concentric....somethign like that). This deficit is where the "groin" events occur. And in a skater who is progressing forward the pelvis can be dropped further into anterior tilt and now you have zero protection in the lower abdominal interval or in the "groin". Certainly training as you suggested is helpful and preventative, so nice suppositions ! If you treat every joint as a cylinder and think that llike 2 hands on a steering wheel, one hand pulling and one pushing to make the turn, that all muscles must be appropriately trained around the cylinder. So what i am saying is that the dead bug and iso holds will have to address not only the posterior external rotators but also the anterior ones (and their anchor......the abdominals). Hence why we train them like we suggest on the new DVD. (some of the anterior external rotators are psoas major, psoas minor, iliacus, pectineus, adductor magnus-longus, sartorius, gracilis, medial hamstring, vastus medialis......to name a few).
hope this helps clarify the problems with hernias and why the keep happening in pro sports.......because the entire cylinder is not protected or trained as such. We have an all encompasing protocol in our office depending on what shows up weak. We are considering a future DVD on this for the next series. Hoping there is interest enough.

Another point worth mentioning is that when the pelvis is flexed forward (ie belly button down toward floor) or "open", the obliques are at a mechanical disadvantage and when the skater goes to accelerate or push off, there is no cylinder rigidity ( I think Kapandji was the 1st to talk about this: Physiology of Joints, Volume 3), thus the inguinal area is subject to herniation ( I believe Dr Allen addressed this in sprinters in another post), so.. a slightly straighter back (in other words, a normal lordosis) is desirable. It is imperative the abs
are engaged prior to the glutes, as the latter will tend to reduce the lordosis and externally rotate the leg, because of an insufficient anchor, making the athlete more vulnerable.

Abdominal iso holds (in a dead bug position) with superimposed glute isos while someone holds the foot and the subject resists against internal rotation (in other words, they are externally rotating against resistance). I am not a fan of open chain exercises (like this one), so I would prefer this done in a standing, skating takeoff position. You could also do a similar exercise on a Reebock slide mat.

As Dr Allen said, we are hoping to address this in a future video. Thanks for the question.
