Quoted message said:I doubt that too many swimmers use scuba or diving fins. They are
too
expensive and probably too big and bulky for pools. Plus they are
usually sold in specialty stores. Most swimmers that I've seen use
snorkeling fins that you can buy for about $15 to $30 at walmart,
or a
sporting goods store. Others use the swimmers' fins that you buy at
specialty swim stores, such as zoomers.
Quoted message said:What Pat was referring to, I think, were monofins. Monofins are
used
along with or without snorkels for pool speed competitions. They
are a
single fin with two slots for both feet. They make you look like a
mermaid. large monofins are also used deep diving competitions.
were
divers don't have to maneuver, but rather swim straight down and
straight up on an elevator. Monofins are specialty fins for speed
w/o
maneuverability. They are no good for scuba or freediving.
Quoted message said:I would think that monofins could be good for teaching butterfly.
Monofins force a good body undulation. They essentially reproduce a
dolphin kick. Body undulation starting with the stomach is
essential
in butterfly. If you ever look at deep diving competitions, those
guys
have a incredible undulation, and that is the secret of good
butterfly.
Regarding your last paragraph about body undulation, yes, I agree.
One
thing I've heard said, but I confess I've never been able to get the
hang of it in my own butterfly swimming, is that good fly swimmer
work
the kick in both directions, not just snapping the feet down. I
imagine
I get some propulsion from coming back up but I know I don't have
that
truly beautiful, dolphin-like undulation I've seen in the best fly
swimmer - it is a wonder to watch when someone gets it right.
And of course we are talking about swim fins, not scuba. I took a
quick
look online, and the places I saw often label them as swim fins. I
couldn't find a scuba fin for sale at any swimming store.
The way I teach it is starting at the head and shoulders. I try to
get
them to load up the posterior chain (back, hips, hamstrings) by
getting
the chest down and the hips up. My running joke with them is that
I'm
not happy if I don't see butts bobbing up and down in the water, and
getting their hips out of the water does seem to help. From that
"loaded" position, the idea I teach is to snap in a wave, starting
with
chest up, moving through hips down and finally to feet down as almost
an
afterthought to the hip motion. I'll have to say that getting people
who can't do fly to actually do it is probably the most satisfying
part
of my swimming teaching since so many people come to the class
thinking
they're never going to be able to do it.
-S-
I used to do fly the way you described. Then someone on this group
posted something about focusing on diving in. I started doing this.
The idea is that you dive into the water and try to tuck the head
between the arms. That seems to generate momentum for the torso to go
in and then bend back at the waist and aim up. I discovered that the
secret of fly is in the stomach and back, not in the arms and legs.
Someone posted a free diving website several months ago. They have
some videos of free divers. I am sure that they have them in you tube.
Check out the undulating motion.
