Hi, I'm new to the board. I've read a lot of posts and think this is a great resource for people. Anyhow, a little background. My 8 year-old son, who has Asperger's syndrome and it's associated errrrr...lack of athleticism, is on the neighborhood swimming team. Surprisingly he really seems to enjoy swimming and gets excited about his improvements. He has improved from a 44 second 25 yard time to 34 seconds in this, his first year. I have never swam competitively but given his interest in swimming, I've developed a similar interest and have been reading about stroke mechanics while watching lots of video of Ian Thorpe and Alexander Popov. Of course I practice it on myself and have become infinitely better. I've been trying to teach my son proper technique as well, with some success. While other kids his age on the team (many more experienced) more or less bully their way through the water faster than him, I don't let him pull as hard as he can or stroke as hard as he can for obvious reasons...so he learns better. He will be taking lessons soon from one of the student coaches, although I'm a little weary about it because they may teach him their own bad habits (not that I'm not, lol). For example, pretty much all the older kids on the team do the classic S-shaped scull.
My question is as follows; I am trying to teach him the high elbow and getting a feel for "hard water". We're also working on timing his hip rotation to use that vertical forearm. As you can imagine, it's difficult for him to rotate the arm and shoulder like that during the stroke, although he can on dry land. I noticed Popov pronating his hand (palm facing out) in the beginning of his catch, which I imagine does 2 things; one, scull a little, and two, get him into the EVF. Is this a pretty standard thing? I don't see Thorpe do it on video, but maybe I'm not seeing it well amid the bubbles. I myself have more or less been able to get a reasonable EVF without pronation, but maybe I should do the same? The second question is do most of you prefer the front quadrant style? Again, Thorpe begins his catch as his recovering arm passes his head and he starts rotating, while Popov begins his catch earlier.
If you could give me advise on these issues, particularly as it pertains to teaching a child, I would be appreciative. Sorry for the lengthy post.

I think that the search for universal truths is a recipe for frustration in stroke analysis. In the go swim video in one clip she is swimming very close to a catch up stroke, only starting the pull when her recovering hand is almost entering the water, later (about the 1:59 mark) you see a totally different timing, starting the pull as her other hand leaves the water. Most people adjust their stroke timing beyond simple tempo depending on whether they are swimming a 50 or a 1500.
Lots of people would strongly disagree but I think that rotation is not about generating torque, it is about positioning your body and limbs in ways that let you use big strong muscles and maximize streamlining and anchor your limbs to best effect given that joints are limited in the ways they can move.
During the stroke analysis session on my last SwimTrek trip the instructor gave a useful demonstration. Hold onto some immovable object with your arm extended directly in front of you and press down. With your other hand feel your lat under the arm you are pressing with. You will note that it isn't very tense. If you hold it for a while you will begin to feel your shoulder muscles tiring. Now rotate so that the arm is now extended directly out to the side and again press down. You should immediate feel the entire lat muscle tense. So being rotated on your side not only makes you more streamlined but it allows you to better engage your lats. You might find it useful to play around with pulling yourself up on the pool edge, trying different hand placements and arm positions to see where you get the most power. You will also find that at full extension above your head your lat is more engaged when your your palm is rotated outward. These are the sorts of things that confound any attempt at analysis that is based purely on theoretical efficiency of propelling surfaces.
When I looked at the first of your videos of your son it looked to me like he was doing a pretty good job of translating his rotation into propulsion, it looked to me like he just needs to get a better anchor/EVF and eventually put a little more muscle into pulling himself past that anchor. It looks like he's got a pretty good foundation. Good luck.
