Any competitive sprinters out there try Total Immersion?
Curious about results for sprinters vs typical long distance target.:worms:
YES T.I. works
It helps swimmers swim with more ease and efficiency
I don't have any data to prove it. The recommendations just make sense and many are the same that I've recommended in
Swim Faster Faster
Stuff Like:
1) keep your head neutral (look down at the bottom) which gives you higher hips
2) use a small kick, to stay balanced
3) move with ease
4) proper rotation
this covers the key ideas

The differences with TI sprinting vs distance is likely to be
+ faster turnover, (faster catch)
+more powerful pull
+ harder, faster more propulsive kick,
but the head position & bodyline are the same.
Long Boat MythInteresting perspective on the boat length topic

great article! So a longer boat has a higher top speed, but takes more energy to go lower speeds than a comparable boat of shorter length.
What does that mean for swimming? How about nothing is as simple as it seems, maybe? I already didnt put too much stock in TIs emphasis on using a catch up stroke. Though there are a lot of things about TI that are great for a novice swimmer trying to improve efficiency.
Interesting article that partially debunks the "longer is faster" notion. Although even according to this article, this principle does hold true at sprinting speeds.
Still, the "length of your vessel" issue is different in swimming from boat design in one important way: short of some macabre surgical procedures, none of us gets to choose our length. We're born with it. So our only choice is what to do with the length we've got. My guess is that for any individual's given length, they're faster (compared to themselves) when they are stretched out and keeping themselves long in the water. I can't back this up with any scientific studies, but it just seems that the only way to be less stretched out is to be somewhat floppier in the water, which seems like it would negatively impact resistance, hence speed.

Quickest BoatsThis boat is built for acceleration
As I understand it,for a swimmers "boat",form drag(the drag from our contact with the water) goes up at roughly the square of speed,whereas wave drag goes up at roughly the cube of speed. Form drag starts as the greater amount so is more important at lower speeds.One can minimize form drag by being as narrow and smooth as possible.One can minimize wave drag by being as long as possible,or eliminating it all together by being underwater(SDK).
