I always thought my streamline wasn't horrible, but then I saw the movie on this page:
www.page.sannet.ne.jp/.../fusiuki_index.html
In it, the swimmer is able to float ~15 M in streamline, and his legs don't sink at all.
When I try this, I can only get about half of the distance he does, and my legs start to sink almost immediately. If I try to keep my legs completely straight I can maintain them at about a ~30-45 degree angle to the water, but no matter what I try I cannot get close to his performance.
Clearly taking a big breath and holding it is important, as well as extending arms out as far forward as possible and pointing toes, but does anyone know anything else to suggest? In some of the links he discusses that anyone can do this, but is a little vague about the details. He mentions that you need to keep your body straight (of course), and also that that the way you rest your lungs on the water is important.
The pages are in Japanese, but some of the pages have diagrams that explain what is he talking about pretty clearly. The page has the best diagrams (the left side of the diagrams is the 'old style', the right side is the 'new (correct) style'.

He also mentions that it isn't about forcing any body part, its about 'releasing force' and floating naturally.
If there are any native Japanese-speaking swimmers and can quickly read through this and let me know a brief summary of his suggestions I would appreciate it. My Japanese isn't bad but there is alot of explanation and some of it a little difficult to understand.
Can anyone do the streamline as far as he does? Do you think it is really possible for any body type? It seems to me that the length of your various body parts, plus distribution of fat would imply that not everyone could do it as well as he does.
I'm willing to work on it, but it seems senseless to work on something that I'm doing wrong and don't know why. My legs sink. I don't remember this being a problem when I was young. I see some of the streamlining videos and the swimmers' legs usually seem to go up...mine go down.
I am pretty sure that every male's legs will sink if you do nothing with them. Mine certainly do. The reason that some streamliner's legs don't sink is probably that they compensate by pointing "down" a little bit.
Because as impressive as it may be to see someone continue to glide seemingly forever, it has very little to do with fast swimming (other than possibly as feedback or maybe even a benchmark to help you develop a tighter streamline).
The reason is that, very shortly after you push off the wall, you should be kicking. And if your underwater kick is slower than your surface swimming, you shouldn't do it for very long. Legs sinking, or not, have little to do with it.
How tight is your streamline while kicking? And -- related to this -- how fast can you kick to 15m? Those are far more significant questions than how long you can glide after a pushoff or dive. That's just a parlor trick.
