Long story short: I was hit by a pickup truck and lost much flexibility in the neck and shoulders (broken neck) for a bit. As a result, when I started swimming again I had a major cross-over problem and no ability to hold a high elbow.
Yeah, this is a crappy way to have to find revelation, but I guess as we get older we take it where we can get it?!? First off, glad that you are recovering.
Your post brings me to a point that I have been exploring a ton in my coaching and my own swimming. It is further echoed by the reviewer in their comment on the first swimmer in this article(posted by FLAJill on ST): http://www.usaswimming.org/...id=4040&mid=8712
That is, the relationship between the neck and the ability to propel effectively. We have long known the role that the alignment of the head can play in the ability to catch and propel (think about the key points for SoL), and as the neck has trauma, it is not uncommon for the requirement of head alignment to be even more severe. If you were to swim a 25 with no breaths, I bet your crossover would be gone and your elbow/forearm position totally dialed (or as least as dialed as your body will allow).
Now, as to the most recent breakthrough that you had, it is reminding me of something that I have been exploring in my own swimming of late, and let me tell you, my body - at least my right side - is about as jacked up as they come. In conversations with KevininMD Iwas turned on to the “analyses lens” of looking at things in terms of internal rotation about the humerus, rather than simply EVF. What does this “internal rotation” give us? For one thing, it gives us a pink finger that is either even with the thumb, or slightly trailing the thumb, in terms of its orientation as a paddle that pushes backwards. Why is this important? Well, I don’t know the specific fluid mechanics of it, but my own sensation is that the hand propels much more effectively when it is pushing back flat, OR when it has A TRAILING NOT LEADING PINKY.
In all, I am musing with the idea that EVF might be more an effect than cause. Trailing pinky might be most of the advantage. Just maybe that is. It would explain some of what we see in terms of only moderately high elbow in elite swimmers, or only 1 arm with high elbow (Tom Dolan). And I think that we can safely say, don’t do a low elbow, because that will almost guarantee a leading pinky.
Regards,
r.b.
I’ll pay attention to the finger positions when back in the pool. Just mimicing the motion at my desk now, however, feels like I’m pushing a high elbow when thumb-leading, and sweeping across my body when pinky-leading.
