Guys, this is the pitfall of the internet. Lots of information and misinformation flowing around and the reader has to try and make some informed conclusion. I'm buying the following:
- Everything that Doug Stern says
- Molecules in a fluid will try and move around the fluid, not under it where there is a larger pressure differential
- Rotating makes us longer and more narrower with half the body outside the water, vs when flat, you have most of the body under water.
- Rotating allows us to use the large muscle groups more effectively
Finally, it is not the frontal area presented to the fluid alone that matters. Its the ratio of the frontal area to the overall length of the vessel. Frontal area being equal, my understanding is that the longer vessel will be quicker. So hip rotation not only gets your narrower up front, with half your body flowing through air instead of water, but also longer, while allowing you to use bigger muscles.
Aztec, I have no clue what you are doing, but there may be many other factors that are enabling your to swim faster while flat than rotated. I suspect that you need to get a coach to look at you live and restart your swim stroke from square 1. There is a chance that you are overthinking things and perhaps simply letting the body go is all that is needed. I do know that when some people rotate (I do this myself), my legs go out of synch and I fishtail. Swimming flat might mean no fishtailing, so you are going quicker. There may be other things going on. Only a live coach will be able to pick things apart.
As slowman said, there is a high cost to good form. There may be a chance that you just need more swim miles before you can implement some of the finer features of good form too.
things apart
I'm about to go for more coaching, but I've had a good dose already. I don't make any *big* errors. Elbows high, tight kick, good body position. Catch needs improvement on the left side, and I need to balance out the timing of my two pulls, as well as learn to breathe on my right side. I don't crossover (though I can if I try :-)), my kick is smooth, feet are pretty flexible and pointed, one eye stays underwater for 75% of my breaths, etc. Point here is the obvious stuff is pretty well covered and OK.
Just to nitpick on some of the above... for your #3) we aren't much "longer" when rotated (well, at least I am not, as per the test mentioned above -- I'd be curious to see how others score), so the longer vessel thing doesn't really apply much. And we certainly aren't higher up the water. Even excellent (including Olympic -- I've seen this) swimmers sink some when on their sides. Try kicking flat, then kick on your side. Now, that said, don't swimmers kick underwater off the wall as long as allowed because they are faster when submerged? Not sure it matters whether we're up higher/lower in that case.
