Gently exit the water at the finish, exit to a nice relaxed elbow high position, then a clean no splash entry. Extend and let the hand drop to the catch. Don&amp;#39;t push water with your palm in the opposite direction when you extend, anchor and apply force of 20 to 25 psi to the finish, don&amp;#39;t make too many bubbles during the catch phase, finish on a comfortable position on the thigh and repeat, repeat, repeat.
I know this is becoming a physics discussion :laugh2:, but here&amp;#39;s my rebuttal.  I think that the catch, while not pressing against solid ground, is analagous to the solid ground in a jump.  Tomorrow I will do an experiment.  I&amp;#39;ll lay in the water on my side, both hands on my hips.   Then I&amp;#39;ll swing the top arm forward and see if there&amp;#39;s any movement.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107869?ContentTypeID=1</link><pubDate>Fri, 29 Aug 2008 09:45:41 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:f9d621f8-6277-4c1e-b37d-c2b75a508d77</guid><dc:creator>taruky</dc:creator><description>Someone around here has a quote from Bruce Lee about being conscious of what one is doing being a bad thing, and man is it true!

That&amp;#39;s funny, it is so true. I have spent months working on my catch and it really kind of hit me a little in the last few days and I&amp;#39;m not thinking too hard about it. Suddenly I feel like I&amp;#39;m holding onto water. I didn&amp;#39;t get a chance to videotape myself, but will tomorrow for sure. I&amp;#39;ve been doing a lot of closed fist swimming, and I&amp;#39;m amazed how well it really works. After doing that, you feel like you&amp;#39;re pushing peanutbutter when you open your hand again.
 
In one of the earlier posts, I believe it was George who said I look like I&amp;#39;m in a hurry to get my hand out of the water. I didn&amp;#39;t really understand what he meant until the last couple days. Now that I feel what holding on is, it makes sense. I&amp;#39;m not sure how high my elbow is (I have to see the film), but I know for a fact I&amp;#39;m feeling the water better than ever. If I could just relax and improve my breathing. I still find myself getting tired too quickly. I&amp;#39;ve tried everything from taking deeper breaths, shallower breaths, belly breaths, barely getting my mouth out of the water...ugh&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107767?ContentTypeID=1</link><pubDate>Fri, 29 Aug 2008 06:34:31 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:c5b75bce-6bdf-47fd-98a8-e8e94972ec0a</guid><dc:creator>Former Member</dc:creator><description>It makes you certifiable, it is called catch 22.

I&amp;#39;m not sure why you say the straight arm recovery is theoretically slower. The upper arm will follow essentially the same path.  Your hand follows a longer path but it is just along for the ride on the upper arm so it follows that longer path at a faster speed ending up in the same place at the same time.  Stroke rate has never been limited by recovery time anyway, the pull and body roll are always the limiting factors.  If anything the straight arm pull may require slightly more energy to accelerate, but again, that&amp;#39;s not usually a limiting factor.

Taruky: on the discrepancy between what coaches say to do and what swimmers actually do Jonty Skinner wrote an interesting article on the effect of scy training on technique, including this quote:
Granted there might be a number of different ways to describe this process, but without a doubt the majority of coaches in world would agree on one fact. That the anchor or catch mechanics should involve an elbow position that is higher than the wrist/hand position.  Looking at figure 1, coaches might argue as to the specific angles of the joints, but I believe all might agree that the upper and lower arm components would be on distinctly different planes.  However, after reviewing underwater footage of hundreds of swimmers, I find that the majority don&amp;#8217;t employ this kind of technique at all.  After continuing to ask coaches to describe their opinion of the catch or anchor position I continued to find a huge discrepancy between what coaches were describing, and what was actually occurring in the water.

the bent elbow recovery promotes smoother entry, for one thing, and, for another, it promotes a quicker approach to the catch point.  if you sidearm your overarm recovery, the curvilinear path that your arm takes will take longer to follow, theoretically, than the more straight path followed by a bent-arm recovery.  however, it is my opinion that there is a bit of range here.  if your elbow is bent too high and your hand kept too close to your body, then the motion will lose its fluidity as the recovery becomes a mechanical transition from unnatural arm positions.  thus, it seems to me that the best course of action is somewhere between a sidearm recovery and a very high-elbow recovery.  There&amp;#39;s been some debate in these forums regarding bent-arm to straight-arm, but for me it is definitely bent-arm with the advantage, but the question is how bent.  If your hand is too far out or too far in, you have a slower recovery, so you need to find that golden mean where the overarm recovery path is fluid and natural but not too long a distance to travel, either.

In the context of Rada Owen, I haven&amp;#39;t seen a video of her, but I would guess that she simply has accustomed herself to a bent-elbow path within that range that is closer to the sidearm side of things than to the highest-elbow.

If you swung your arms up after you feet left the ground the would reduce the height of your jump. Unless you launch your arm by pressing against the water you are essentially doing the recovery in the air and as your muscles throw the arm forward an equal and opposite force is pulling backward on your shoulder and body, so you slow down when you start the recovery and then speed up at the end as the momentum in your arm pulls your shoulder forward.

Rada Owen was the demonstrating swimmer. Marsh would talk some about high elbows, but Owens&amp;#39; elbow was definitely not very high. Her catch is somewhat of a hybrid between the EVF and straight arm pull, where the upper arm is more sloped and thus the bent elbow occurs but much lower in the water. I understand that the main reason for the higher elbow EVF is to begin anchoring farther in front of you than you would otherwise. 
I&amp;#39;m curious how many of you catch like Rada. It certainly lookes easier. Kind of odd that they chose her to demonstrate, while Marsh would show a higher elbow when demonstrating outside the pool. 
 
The other thing I noticed is that they tend to teach a little more of a swing or throw to the arm recovery. One drill in particular which caught my attention was the catch and throw drill. I&amp;#39;ve always thought of my recovery as a more deliberate raise the elbow, move it forward, then put it in the water type of thing. But it kind of makes sense to have a little bit of a throw to it, allowing you to create some momentum over that catch. Am I correct in this thinking? I feel like up until now even when I do get a reasonable catch I&amp;#39;m having to pull back more rather than just riding momentum. 
 
I&amp;#39;m off these next couple days so I&amp;#39;ll try to get some video of myself. A little bit of a lightbulb came on my last swim (couple days ago), and I&amp;#39;m anxious to see if you guys feel I&amp;#39;m in the right direction.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107422?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 09:11:43 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:36e7cc4a-0aad-4cb0-bf82-4cfb4902785c</guid><dc:creator>Former Member</dc:creator><description>I have 2 of these &lt;a href="http://cgi.ebay.ca/UNDERWATER-Video-Camera-Popular-Color12pcs-Led-Light-24_W0QQitemZ280258927206QQihZ018QQcategoryZ4703QQtcZphotoQQssPageNameZWDVWQQrdZ1QQcmdZViewItem"&gt;cgi.ebay.ca/UNDERWATER-Video-Camera-Popular-Color12pcs-Led-Light-24_W0QQitemZ280258927206QQihZ018QQcategoryZ4703QQtcZphotoQQssPageNameZWDVWQQrdZ1QQcmdZViewItem&lt;/a&gt;

The issue is with your basic underwater cameras at best you can get about 10-15 feet of someone swimming at race pace as it is really difficult to stay on the swimmer.  What I meant when I referred to underwater camera is a boom mounted camera with an external screen where it is much easier to remain centered on the swimmer.

I too have that camera!  With a good set of fins the cameraman should be able to get an ok shot of you as you overtake him.  While it is ideal to get a tracking shot of a whole length even a few stroke cycles can help point out some of the more prominent issues.  And many issues will show up at less than top speed as well.   Well, I have had no problem finding problems with my stokes anyway! :o

I have been wondering if I could cobble together a way to mount the camera on the end of a pole, and just learn by practice how to keep it trained on the swimmer.  I&amp;#39;ve thought about just using my tripod upside down, but I&amp;#39;m not sure how well it would stand up to regular immersion.

I would also like to get a weight belt or the equivalent to make it easier to stay underwater, particularly for shots from directly underneath.

Sometimes it&amp;#39;s better to make due with what one has than to hold out for the ideal solution!&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107214?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 08:41:48 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:9026930d-c2e6-4234-9047-30ad8f82df60</guid><dc:creator>Former Member</dc:creator><description>The difference with land based versus water based movements is that when you jump you throw your arms up while your feet are still pressing on the SOLID ground.

I also bought a GoSwim video with Roland Schoeman, and one of the things he does is throw the shoulder.  I agree that it wouldn&amp;#39;t be the main source of momentum, but would it not be like swinging your arms forward while jumping?  I think most of us can jump higher and farther with an arm swing than without.  In the case of jumping, the legs are the main propulsive element but the arms do contribute propulsive work.  In swimming, the catch arm is the the main propulsive element, but similarly I would think the right arm could do the same.  A little experiment to try; stand up straight but don&amp;#39;t try to dig your feet into the ground.  Then do an forward overarm swing, and watch how you lean forward.
 
Again, I&amp;#39;m not in any way advocating a strong throw or anything.  But I think a little velocity or swing on the recovery will add to propulsion.  Now if the timing is all off the energy could be completely lost.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107012?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 07:05:06 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:f26fa1ac-87b9-4939-adb0-327dbacef265</guid><dc:creator>Former Member</dc:creator><description>Sean, try this:  hold your arm out straight to the side, keeping it straight swing it to straight in front of you.  The hand travels a longer path than the elbow but they both arrive at the front at the same time.  The hand simply moves along its path faster.

It does require more torque or the same torque applied for a longer duration to accelerate the hand to the higher speed, but I see no evidence that that is a limiting factor.

Since your arm can&amp;#39;t actually generate any propulsive force in the fully extended position, isn&amp;#39;t that extra little extension more about stretching and engaging the lat?  The only way to generate any force out there is to flex your wrist, but even then you have to be pulling it back faster than you&amp;#39;re moving forward through the water.

as far as the sidearm vs the bent-arm goes, i&amp;#39;ll agree that it requires greater force to accelerate the hand to the higher speed that would be required in such a stroke.  however, i imagine such a stroke would limit one&amp;#39;s ability in distance events, as the greater force required would fatigue the swimmer that much faster.  The speed that the hand must travel to keep up with the speed of the elbow would take its toll on the swimmer.

my understanding of that extra stretch is that it gives that much more runway for your pull while not affecting the timing of your stroke, since the pull is finishing out at the same time.  it&amp;#39;s definitely not about, in itself, generating propulsive force, though.  no portion of the recovery is.

in talking to eamon sullivan&amp;#39;s biomechanist, he seemed to agree that the sidearm recovery took longer than the traditional bent-arm recovery, but: a) he didn&amp;#39;t think it would affect the pull rate of eamon, and b) he didn&amp;#39;t explain to me why he felt that such a recovery would take longer.  My guess is that your upper arm may follow the same path in both, and your lower arm may be along for the ride, but the catch starts at the fingertips, and it takes longer for those finger tips to get into position if they are following a more curvilinear path.  In bent-arm recovery, the fingertips follow tangentially to the smaller semicircular path created by following the movement of the elbow.  in sidearm, the fingertips follow parallel to the elbow&amp;#39;s path in a larger semicircle.  Essentially, where sidearm follows the perimeter of that larger semicircle, bent-arm streaks down the diameter.  

turuky:

to my knowledge, the rotation of the body does a few things.  first, it reduces your drag by narrowing the amount of surface area splitting the water.  second, it allows your reaching hand to reach that little bit farther that you could only reach by dropping that shoulder.  third, it helps convert the pulling hand&amp;#39;s final push to the outside to a push behind by changing the positioning of the body and therefore the effect of the push.  it&amp;#39;s really quite useful.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/106710?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 05:38:16 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:f61c248b-9177-4b8c-868d-0a80abbadbe5</guid><dc:creator>Former Member</dc:creator><description>I was really referring to her underwater catch.
 
As far as the recovery, I&amp;#39;m not thinking so much in terms of the arm position on recovery as much as the speed and momentum of the recovery (shoulder and elbow moving forward). Rotating the body alone doesn&amp;#39;t really provide much forward propulsion it seems to me.  Given that the catch arm is really supposed to be holding water, there must be a source of momentum somewhere.  Let&amp;#39;s say that someone very slowly and deliberately moves their recovery arm forward.  The only way to get propulsion would be to push backward with the catch arm.  However, if there is forward momentum to the recovery, the catch arm can more or less hold water while the body glides past.  I think one of the things I really need to remember when swimming is to hold off on rotating until my recovery shoulder/arm has slid forward more.  That&amp;#39;s what Marsh was mentioning and what I see from the better swimmers.  
 
I&amp;#39;m in no way thinking that I should really throw the shoulder mercilessly and risk injury.  I just need to think in my mind &amp;quot;more forward momentum&amp;quot;.  Does that make sense, or am I way off here.  I need to get to the pool today and test this out.

No!  You do not get propulsion from the recovering arm!  Any forward momentum you gain as the arm decelerates at the front is momentum you lost as you accelerated the arm forward in the back.

Propulsion comes from the force you are applying to the arm that is anchored.  Think of hanging on the edge of the pool with your hands on the edge as you pull yourself up out of the water, you want your hands to stay in the same position and your body to move past them.  This is easy on a solid wall.  The nature of fluids is that they move when you apply force to them, the idea of your hand actually staying still as you pull is physics nonsense but you want to get as close to that as possible.  The larger surface you press/anchor with, i.e. hopefully your hand plus your forearm, the less slip you will get for a given amount of force applied, that is the purpose of the high elbow pull, to maximize the area of the surface that is oriented backward and applying backward force.  If you take a picture from directly behind you the area that your arm takes up in the image is the effective surface area that you can use to exert force on the water.  If your forearm is in a plane parallel to the plane of the wall at the end of the pool that area is maximized.  If your arm is extended directly toward the wall the area is very small, which is good for reducing drag/streamlining.  Any angle in between will produce an intermediate sized effective area.

Think of pushing a kickboard through the water, when the largest side is facing the direction you are pushing it you have to push quite hard before it moves fast or far, turn it so that the edge is facing forward and the effective area becomes quite small and even small forces will slip it through the water easily.  If the board is at 45 degrees an intermediate amount of force is needed to move it, and sideways forces are also generated.

Remember that pressure forces in a fluid are always at right angles to the surface, so if your arm is at a 45 degree angle the forces generated will be equal parts upward and forward even if the direction of movement is straight backward.  With your arm extended directly in front of you any force that you generate will be straight down and pretty much wasted effort.  With a straight arm pull the majority of the force you generate will be vertical until you get to 45 degrees, so it&amp;#39;s not an economical way to swim.

And you are correct, rotation in itself doesn&amp;#39;t provide propulsion, what it does do is improve your streamlining and put your arm in a position where you can apply larger muscles.  Extend your arm directly out in front of you and press down on something, feel the lat under the arm you are pressing with, it isn&amp;#39;t engaged.  Extend your arm directly out to the side and press down on something, immediately your lat is engaged.  By positioning your elbow out to the side prior to the power phase you can effectively utilize your nice big lat muscle instead of the relatively small shoulder muscles.  Experiment with lifting yourself up at the edge of the pool with your arms straight out or with your elbows pointed downward versus with your elbows wide out to the side, you should feel quite a difference.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107194?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 04:26:25 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:b027d907-779d-4581-a138-107c24c7bc7d</guid><dc:creator>pwolf66</dc:creator><description>I have been using the Olympus Stylus.

I have that same camera. The issue is with your basic underwater cameras at best you can get about 10-15 feet of someone swimming at race pace as it is really difficult to stay on the swimmer.  What I meant when I referred to underwater camera is a boom mounted camera with an external screen where it is much easier to remain centered on the swimmer.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107172?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 04:15:12 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:aabb8aae-25d7-4e9e-aacc-438b9e96fa9c</guid><dc:creator>taruky</dc:creator><description>After reading thru all this and looking thru the USMS Swimmer magazine, I have come to the conclusion that MY CATCH SUCKS!!!!

You do not get propulsion from the recovering arm! Any forward momentum you gain as the arm decelerates at the front is momentum you lost as you accelerated the arm forward in the back.
 
Propulsion comes from the force you are applying to the arm that is anchored. Think of hanging on the edge of the pool with your hands on the edge as you pull yourself up out of the water, you want your hands to stay in the same position and your body to move past them. This is easy on a solid wall. The nature of fluids is that they move when you apply force to them, the idea of your hand actually staying still as you pull is physics nonsense but you want to get as close to that as possible. The larger surface you press/anchor with, i.e. hopefully your hand plus your forearm, the less slip you will get for a given amount of force applied, that is the purpose of the high elbow pull, to maximize the area of the surface that is oriented backward and applying backward force. If you take a picture from directly behind you the area that your arm takes up in the image is the effective surface area that you can use to exert force on the water. If your forearm is in a plane parallel to the plane of the wall at the end of the pool that area is maximized. If your arm is extended directly toward the wall the area is very small, which is good for reducing drag/streamlining. Any angle in between will produce an intermediate sized effective area.
 
Think of pushing a kickboard through the water, when the largest side is facing the direction you are pushing it you have to push quite hard before it moves fast or far, turn it so that the edge is facing forward and the effective area becomes quite small and even small forces will slip it through the water easily. If the board is at 45 degrees an intermediate amount of force is needed to move it, and sideways forces are also generated.
 
Remember that pressure forces in a fluid are always at right angles to the surface, so if your arm is at a 45 degree angle the forces generated will be equal parts upward and forward even if the direction of movement is straight backward. With your arm extended directly in front of you any force that you generate will be straight down and pretty much wasted effort. With a straight arm pull the majority of the force you generate will be vertical until you get to 45 degrees, so it&amp;#39;s not an economical way to swim.

Extend your arm directly out to the side and press down on something, immediately your lat is engaged. By positioning your elbow out to the side prior to the power phase you can effectively utilize your nice big lat muscle instead of the relatively small shoulder muscles. Experiment with lifting yourself up at the edge of the pool with your arms straight out or with your elbows pointed downward versus with your elbows wide out to the side, you should feel quite a difference.
 
I also bought a GoSwim video with Ronald Schoeman, and one of the things he does is throw the shoulder.  I agree that it wouldn&amp;#39;t be the main source of momentum, but would it not be like swinging your arms forward while jumping?  I think most of us can jump higher and farther with an arm swing than without.  In the case of jumping, the legs are the main propulsive element but the arms do contribute propulsive work.  In swimming, the catch arm is the the main propulsive element, but similarly I would think the right arm could do the same.  A little experiment to try; stand up straight but don&amp;#39;t try to dig your feet into the ground.  Then do an forward overarm swing, and watch how you lean forward.
 
Again, I&amp;#39;m not in any way advocating a strong throw or anything.  But I think a little velocity or swing on the recovery will add to propulsion.  Now if the timing is all off the energy could be completely lost.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/107130?ContentTypeID=1</link><pubDate>Thu, 28 Aug 2008 03:13:35 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:76c2f42e-f109-42ee-b2fe-d3c2eb3c2f13</guid><dc:creator>pwolf66</dc:creator><description>After reading thru all this and looking thru the USMS Swimmer magazine, I have come to the conclusion that MY CATCH SUCKS!!!!

the bent elbow recovery promotes smoother entry, for one thing, and, for another, it promotes a quicker approach to the catch point. if you sidearm your overarm recovery, the curvilinear path that your arm takes will take longer to follow, theoretically, than the more straight path followed by a bent-arm recovery. however, it is my opinion that there is a bit of range here. if your elbow is bent too high and your hand kept too close to your body, then the motion will lose its fluidity as the recovery becomes a mechanical transition from unnatural arm positions. thus, it seems to me that the best course of action is somewhere between a sidearm recovery and a very high-elbow recovery. There&amp;#39;s been some debate in these forums regarding bent-arm to straight-arm, but for me it is definitely bent-arm with the advantage, but the question is how bent. If your hand is too far out or too far in, you have a slower recovery, so you need to find that golden mean where the overarm recovery path is fluid and natural but not too long a distance to travel, either.
 
In the context of Rada Owen, I haven&amp;#39;t seen a video of her, but I would guess that she simply has accustomed herself to a bent-elbow path within that range that is closer to the sidearm side of things than to the highest-elbow.

I was really referring to her underwater catch.
 
As far as the recovery, I&amp;#39;m not thinking so much in terms of the arm position on recovery as much as the speed and momentum of the recovery (shoulder and elbow moving forward). Rotating the body alone doesn&amp;#39;t really provide much forward propulsion it seems to me.  Given that the catch arm is really supposed to be holding water, there must be a source of momentum somewhere.  Let&amp;#39;s say that someone very slowly and deliberately moves their recovery arm forward.  The only way to get propulsion would be to push backward with the catch arm.  However, if there is forward momentum to the recovery, the catch arm can more or less hold water while the body glides past.  I think one of the things I really need to remember when swimming is to hold off on rotating until my recovery shoulder/arm has slid forward more.  That&amp;#39;s what Marsh was mentioning and what I see from the better swimmers.  
 
I&amp;#39;m in no way thinking that I should really throw the shoulder mercilessly and risk injury.  I just need to think in my mind &amp;quot;more forward momentum&amp;quot;.  Does that make sense, or am I way off here.  I need to get to the pool today and test this out.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/106271?ContentTypeID=1</link><pubDate>Tue, 26 Aug 2008 14:52:11 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:92a68918-91d1-44ae-a8a8-0df89f468fa1</guid><dc:creator>Former Member</dc:creator><description>Sounds like you have made excellent progress!

I got a short clip of my fly when I was taping my friend yesterday, was very frustrated to see an old problem with my kick had reemerged! :(  Old habits are really really hard to kill!  Oh well, at least I caught it before practicing it even further.  Thank goodness for video!&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/106046?ContentTypeID=1</link><pubDate>Tue, 26 Aug 2008 14:46:00 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:76710f3b-c57e-4ffa-a9ad-90260d4dce6c</guid><dc:creator>Former Member</dc:creator><description>OK, so I&amp;#39;ve been watching this video over and over:

&lt;a href="http://www.youtube.com/watch?v=XiFR0k3bVI8"&gt;www.youtube.com/watch&lt;/a&gt;

Lindsey, you mention that in that top frame, you see the palm of turuky&amp;#39;s hand, and i&amp;#39;m pretty sure i know why.

when turuky submerges his hand into the water, he -- as we have already mentioned -- pushes the water a bit.  i counted time on the strokes from when the hand enters to when the hand begins its pull.  1 complete second.  it seems to me that what turuky is doing is not so much consciously pushing the water after all, but simply riding the wave a bit.  he&amp;#39;s zipping his hand forward through the water, and -- like any good aerofoil -- it catches air, so to speak.  as the hand catches lift from the resistance it meets up front, it causes the hand to move skyward.  thus, we see his palm.  at the end of that extension forward, then he begins his catch, starting from an upward hand position.

so, my advice to turuky:

your pull should continue under your body using your hand and forearm as an oar.  at the point where your hand-forearm oar bisects your body into its top and bottom halves, you will find that following through with your push requires that your forearm break form to allow your hand to continue on the same path. When your hand reaches the thigh, you will find that the hand can no longer follow along the path.  you&amp;#39;ve simply run out of arm (arm A, we&amp;#39;ll say).  to get your hand back to your side, you have to push the water to the outside and behind you.  At that point where your hand pushes the water to the outside, that is when you rock your body a bit.  the shoulder on the same side as the hand pushing outward should rock upward.  the shoulder on the other arm (arm B) will, thus naturally rock a bit downward.

if you&amp;#39;ve ever reached under a bed to get something deep underneath, you know that you can get that little bit more out of your arm by dropping your shoulder.  that&amp;#39;s the idea with arm B.  when your hand on arm A reaches the end of its path and needs to push to the outside, that is when your other hand-forearm oar on arm B should dive into the water.  as the one hand on arm A pushes to the outside as that shoulder lifts a bit, the other shoulder on arm B should dip just enough to allow the hand of arm B to thrust forward underwater just that little bit more before starting the catch.  it should be the smallest fraction of a second, not a full second count, and arm B&amp;#39;s drive forward in such a manner should be powered by the finish of the hand on arm A.  As soon as the hand on arm A finishes to the outside, the hand-forearm oar on arm B should start pulling.  A quick recap: the hand on arm B entered the water in the form of the hand-forearm oar and did not break position as it reached that last bit forward or as it started its catch.  it won&amp;#39;t begin to break position until it must at the point where the oar bisects your body.  thus, the palm will never be seen, as that would require breaking form on the hand-forearm oar.

i hope that&amp;#39;s helpful and not too confusing.

And it was not one of those glide glide glide until I come to a complete stop type deals either. I did not have anyone recording me, so I&amp;#39;m not sure which areas exactly I improved on, but I must have been doing something better. Things I concentrated on;
1. Fully extending. I found this easier when doing # 2 below.
2. Keeping my wrist and fingers ever so slighly flexed on arm extension. I think someone mentioned this before, but by doing this the water wasn&amp;#39;t pushing my arm into a bent position.
3. Keeping my forearm relatively pronated on extension. What I mean is that my forearm is pronated relative to my rotated body, so that it&amp;#39;s orientation is just as it would be if I was flat/not rotated. In my mind this might be the single most important thing I did, because I really felt the catch and propulsion much better.  Also it seems to control overrotation.
4. Catching a little lower in the water. In other words, my extended hand was deeper in the water than before. 
5. Hand entry farther on recovery. This is the change which I&amp;#39;m really curious to see on film. It felt good, but someone might comment that I&amp;#39;m slapping water or something. 
6. Forcing myself to swim downhill. One interesting thing that came to my mind while I was experimenting. Previously I had thought of swimming downhill in terms of balance. While this is true, today I thought I would try to pull myself downhill as well. I remembered the comments on my forearm not being perpendicular enough to the pool bottom and that I was creating more lift, so I worked on overcompensating by trying to descend.
 
I&amp;#39;ll keep working on it and try to get new film in a few days. Thanks again for the help.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Please critique</title><link>https://community.usms.org/thread/106149?ContentTypeID=1</link><pubDate>Tue, 26 Aug 2008 09:03:16 GMT</pubDate><guid isPermaLink="false">3187ac58-ba85-4314-b79a-c45cd885e09a:edb68b4e-788f-4be8-87a1-dde1a8e2a76f</guid><dc:creator>Former Member</dc:creator><description>USS Swimmer Magazine, Sept/October has some nice stuff on Freestyle Makeover.

A couple of things I did not like about her new stroke, just a little early stage elbow dropping, and I do not like the fingers in the up position on the extention this leads to elbow dropping.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
