When I first heard this from Vern Gambetta I didn't know what the hell he was talking about. "The Core" is a very vague term to begin with. So I always find it surprising to find it in many scientific journals. This time in this month's JOSPT- "Shoulder Injuries in the Overhead Athlete". Don't get me wrong, there's lots of good stuff here by top notch researchers/practitioners Wilk, Andrews et al. It was a combination of this article, plus seeing the "tea cup" exercise on the Iron Maven's website that got my wheels spinning. As you watch Steve Cotter go through the exercise, it is interesting to watch his torso adapt to the various shoulder positions. Not something you would think of as core training, but it definitely fits.
I found it well, kind of annoying that the importance of "lumbopelvic" & "core" training was only given lip service. What did they mean by "core stabilization training"? Does this mean they choose to train this region isolated from the rest of the body? After all, the isolated, uniplanar, unidirectional stuff had lots of pictures- even online videos. Upon watching them it is obvious the core is used isometrically to splint the body's extraneous motions. But is this what happens in vivo?
My buddy Pat Donahue & I prefer, and have had good success with an integrated approach using specific combos of lunges with arm drivers. I think some of the new myofascial research backs up the efficacy of this approach. So, I really don't see this as "outside the box"thinking at all. Baseball season is coming up, so you will see me posting on more shoulder/elbow stuff in the coming months.
