In our office we have found that the Prager Scleral Shell is easiest to use, and gives very consistent readings. Ossoinig Scleral Shells are lighter in weight, easing probe manipulation, and can be obtained from:. Figure D — Note the typical immersion measurement consistency.
When the ultrasound beam is properly aligned with the center of the macula, all five spikes cornea, anterior and posterior lens capsule, retina and sclera will be steeply rising and of maximum height. Changing to this technique is an important first step in improving the overall accuracy of your A-scans.
Measurement consistency from one measurement to the next is often outstanding, due to the lack of corneal compression and the fixed position of the ultrasound probe over the surface of the cornea.

While standing or upright, pull head back and up and pull chin in so that cervical spine is maximally straight and then your neck will be as long as possible, while supine or swimming, push the back of your head back or up, almost out of the water so that neck is long.
With your neck long then your shoulder muscles have maximum amount of room to operate. Then you can lengthen your arms by pulling your shoulder blade towards you ear.
also, opening the chest as you breathe you can use the same muscles you breathe with to help roll the ribcage with respect to the pelvis. Twisting of the spine is an action not only of the obliques side abs but of the intercostals.
Tim, thanks for sharing this. The breathing is what freaks me. I do OK if I swim on my back. I see your tips on it in the post. Thanks again! The difference between trying to powerhouse through the water vs. effortlessly gliding through the water is simply night and day.
Jessica — they do teach you how to breathe properly. One of the things about TI is that you turn your whole body to take a breath vs turning just your head which constricts your airway and makes it tough to take a breath! I used to get really winded when swimming, almost gasping at times, but after learning TI breathing is natural and easy.
Great post. I have been trying to learn to properly swim for quite some time. Now i feel i have the tools.
Now i just have to get to it! BTW…Please, Please PLEASE! Fire up the GEAR segment! Your adding all this great stuff! Please delegate someone to pull it together for us, the starving masses..
lol It says its coming soon…so lets see soon! Keep up the good work Tim…You inspire us more than you know.
And here you are now posting about it! Is there a triathlon in your line-up of things to do? I did it in just 40 days now… Ofcourse I added ABS training and 2 hours swimming, 1 hour cycling and weekly 5K jog. And… Hey I got an excellent V shape… all weight across waist gone with a flat ABS….

It must fit tight. Excess material welcomes water. hey tim, i allready posted in this thread about swimming, but now i have something differnt to talk about that i hope will catch your attention.
being in college though, means my money is tight, and its hard to give at times. but your book also got me thinking about alternative ways you can do things, and in ways that are more efficient, as well as exploiting niches.
my idea is fairly simple, people donate thier old and working computers, and then the charity would give them to underprivileged schools and familys who can use them.
now i know, similar programs allready exist, but heres where mine differs. my idea is to target gamers as the core donatory. why gamers? becuase they are a relativly unexploited nich, and with childsplay as an example, they are very willing to give back.
further more, gamers tend to upgraded thier computers far more offtened than your average person, and thier old parts take longer to go out of date for general computer use.
further more, they are more likely to upgread a few parts, but not the whole computer, which means they upgread more regularly. many gamers end up with old parts sitting around. what if we took those parts in as donations, built computers with them, and gave them to those who can use them?
with that I have thought of an idea on how to give back to those who need it most. while i have thought out many of the benefits to my idea compared to other ideas, and how to go about getting the word out and get donators, im not sure where to look to make sure that those donations get to those who need it.
is there any way you could help me? i know you have many connections and alot of experiance with this sort of thing. i know a little off topic, but i wanted to get the idea to you.
any help you could give with this would be much appreciated. I got a problem with treading water in the vertical position. I can tread only on my back with arms sculling. Any tips from any of you guys would be great! BTW… if you want to get really, really lean… really, really quick, swimming can do that for you.
a vertical position. Hi Tim, I have to say that you really inspired me. After reading your article I enrolled for a TI course here in Prague, Czech republic. All the best, Mike. I earlier promised a url for a free pdf.
This is a 30 to 40 page book that explains a lot about why humans have such difficulty with swimming well, or efficiently or very far — and how to reduce drag and save energy to increase your endurance and speed, by doing less, rather than more.
There have been some really powerful athletes, swimmers, and dancers in both sides of my family. I can feel the connection between dance and swimming, and I have always experienced being exhausted while swimming. Now I understand what I have needed to do with my head, arms and legs, and that the way I was taught to swim as child in camp,etc has literally been a drag.
Also I am recovering from a severe injury and have intuitively known that swimming would help restore me. It seems like this immersion method is more of a natural way to swim. I think your idea is excellent.
How to ensure you implement the donation program correctly? Another approach would be to work with one of these programs for a short period of time to get paid to learn how the system works. The TI series is indeed a very good series. As a coach on the U. National Team, I can say that many of these techniques are used in coaching the top level athletes although more time is spent putting in yardage!
TI gives you many techniques to think about, but I would tell you the main thing to think about is body position and body line in the water.
In my experience, many people particulary masters swimmers get SO caught up in the little technical things that other areas are sacrificed mainly racing!
If you get a chance to watch any water polo in the Olympics pay attention to the underwaters cams — they get great shots of eggbeater. Eggbeater is really just an upright, modified breaststroke kick done with each leg individually.
You want to be careful of your knees when your practicing this at first. You can try holding a kickboard at the surface with your arms draped over the flat portion.
Then try doing a few breaststroke kicks upright. Then try doing a breaststroke kick with one leg at a time. This might feel a little awkward. Eventually you will end up with a fluid motion kicking one leg after the other that actually looks a bit like an hand-crank eggbeater used in baking.
You can tread water, have a conversation with folks and feel comfortable treading for long stretches of time. Safety first. This sounds very similar to modeling, and has been proven effective to learning new things. As long as you have an expert, who is willing to teach, teach you all they know, in a format that makes it easy to learn, you will quickly step up to a higher level.
Unfortunately, modeling works best with a real expert, someone who has actually won championships, etc. This why reading a just an ordinary book on a topic may not as effective learning. I started swimming about 4 years ago—prior, I was a terrible swimmer. Two lengths and I would be exhausted.
Every time I got in the water I was afraid I was going to drown. Some other tips that I found helpful—getting a breathing rhythm down. When I breathe, I only inhale. I slowly exhale through my nose while my head is under water and over the course of three strokes.
Then I inhale my next breath. This led to sometimes not getting enough air, leaving me gasping by the next gulp for air, increasing sense of desperation and creating a vicious cycle. By only doing one thing, I guarantee getting enough air until my next breath. I really rely on my hips when I swim.
Makes swimming almost effortless. In fact, I hurt my feet two years ago and swimming was my only form of exercise during that period. Now, I still do a small kick, but only as a balance check. I learned how to swim with this method.
It is absolutely the best! I often have people who have swam for years complementing me on my speed and style. I only wish that there were other methods like TI for other sports.

but quite similar. At the weekend, indeed I was talking to the swimmer who had given that advice, who was wearing a wetsuit, and in winter pool training was focusing exclusively, as I expected, on stroke count reduction by increasing distance per stroke.
Oh, I just remembered, Penny Palfrey, probably the best non-FINA marathon swimmer in the world right now, apparently has a stroke rate of Triathletes using T.
have a wetsuit to cushion this effect of slower stroke rate to keep them warm. Removing a wetsuit and keeping a low stroke count is a recipe for hypothermia in cold water.
More than anything else in cold water you must be able to maintain a steady consistent stroke rate. I was 70 strokes per minute almost every measurement , never dropped below 68, never went higher than An old S.
Gábor stayed at 68 if I remember correctly, after he settled down after the first two hours he was up toward 80 at the start, excitement and the effects of tapering priming him for a nervous muscular explosive start.
I can just feel the rate by now. This is a vital skill and very different from pool swimming. I know people who have come from a competitive pool background and never once thought about stroke rate.
You must combat this by internal thermogenesis. Separate from the heat retention aspects, what I find myself is that there are consequences to my stroke that come from open water swimming. If you watch most OW swimmers, you will see that they have a high hand recovery, quite different to pool swimmers, which comes about as a consequence having to lift the hand higher to avoid it crashing into chop.
This is sure to also reduce your rotation, which in turn increases your stroke rate. Then there is the effect of sighting, where you have to lift your head, like you never would in the pool, which again, will change your body position and therefore stroke mechanics.
But remember, at any temperature below about 24° Celsius, eventually, you will become hypothermic. For those of us for whom 24° C is much warmer than we ever get, we tend to forget this.
But in cold water you must swim to keep yourself warm, because you are literally swimming for your life. I read about total immersion and swim smooth and originally wanted to go T. initially, and incorporated drills from T.
in my routine, including catch-up drill, and stroke count ladder try to decrease, then increase again. However, unfortunately the university triathlon swim squad I am joining is a swim smooth squad, and the coach tells me to dump the practice of reducing stroke count.
The squad is known to produce channel swimmers. The coach then tried to increase my stroke rate to the extent I am overheating seriously in a warm pool but sustainable in cool or even cold water. Like Like. Those T. was just good at presenting drills. You can find most of them in the old Ruben drill bnook, which has beeen around for decades.
My stroke rate is lower in the pool, but is higher is the sea. Hey thanks for the great discussion here. We spend a lot of time helping new coaches understand the relationship between rate and length.
That converts to more forward movement and THAT usually is a little more efficient. However we see the opposite as well…folks, even coaches, who have spent so much time trying to reduce stroke count that the stroke becomes inefficient, meaning that the trade off of effort vs forward locomotion is actually decreasing, despite stroke length increasing.
We of course then expect that our coaches will pass that information along to swimmers, but if a swimmer has a limited exposure to a coach we work on those most fundamental technique issues first.
I hope that helps clarify some things, or if not I welcome personal correspondence from you or at my website or on the forums. I have just completed some TI training x3 3 hour sessions. I can say that the coaches never once mentioned gliding or focused on reducing stroke rate.
Last night, many of our drills were about deliberately increasing SR. The real theme of the method, as it seems to me so far, is on swimming effortlessly. As a note, prior to this TI course, I had spent some time reading all the Swimsmooth material I really wish they would run a clinic in my town sometime — I have emailed Paul N a couple times about this already.
It would certainly be a good thing to see TI change and improve their approach! What about focus on catch? Pingback: Triathlon Swim-meister IV: Watch Out Luv « The 5k Runner.
Then I realized it is about efficiency no matter what your stroke looks like. I branched out from TI and went to Swim Smooth, and I must say that once I started to swim the Swim Smooth way, my stroke rate increased and my m time decreased.
That is absolutely separate from the case of maintaining body core temperature. BUT, I must say that my Dart 10K in 15C water felt much more comfortable using my SS increased stroke rate than my Danish 2K also in 15C water felt using TI.
This is why I find Swim Smooth to be a superior approach — because they specifically incorporate two different models of efficient swimming. The swinger model works well for a lot of people in open water, and this is a weakness in TI for people trying to apply its concepts to OW settings.
I love the example of Janet Evans. The fact that the greatest distance swimmer of all-time male or female does almost everything wrong from a TI perspective would seem to present an uncomfortable problem for them.
This is a fallacious argument. TI is about getting the most out of every stroke… no matter the stroke rate. It is up to every swimmer to impose the most effective SR for the task at hand. are concentrating on the wrong thing or are remembering the wrong aspect of what they should be learning?
What I mean is, have I been unlucky or are some of the T. I bought the book in Indonesia and figured if I was staying with my friend who lives in Kuala Lumpur and had a pool, that was the time to learn.
Alas, I procrastinated on reading the book for a few days. A few weeks later, however, I was proud to say I can swim. Not so much that of a drowning rat.
I initially went straight into the total immersion drills and found I was struggling with the ideas, especially floating. Floating has always been something that I struggled with.
In Lake Toba I tried a little bit before reading the book but would retreat to the jetty after a few seconds of letting go. This is on a jetty in Lake Toba.
This was one of my better ideas as it helped me understand the total immersion method a whole lot more as well as giving me some key thoughts I can use every time in my life. Here are a couple of my favourite passages I highlighted on the kindle:. The longer you stay on your side in each stroke cycle, the farther and faster your body will travel.
The fastest, most efficient swimmers in the world cut the water on their sides, rolling from one side to the other with each stroke and staying on each side for as much of each stroke cycle as they can; The advantage is simple to understand. You slip through the water more easily that way than on your stomach.
I can float! This is essentially drill one of the total immersion learning strategy. What happens if you push a beach ball into the water?
The water pushes it right back out. Call it your buoy…press the buoy into the water and the water will press back. But keep pressure on that buoy and you force the water to push your hips up instead.
Just what you want. Simply letting water pressure ease them to the surface takes far less energy than trying to prop them up by churning away with your legs.
These were a few of the gems. The hips were something I struggled with. My legs would sink and my hips would follow. When I tried pushing down on my newly discovered buoy, the feeling of my hips popping up was crazy, like I had a rope tied around my hips pulling me up to the heavens.
I soon found myself on Kapas Island, where I continued to practice the first couple of drills. My new struggle was actually moving forward. When I was floating I would be kicking yet I barely moved. I would slowly but surely spin around in a circle. It would be pretty funny to see from a drone now that I think about it.
The breakthrough for me was in that my legs were not kicking properly. Not what you are supposed to do when swimming.
It took a while, but I was then able to complete laps just kicking using just the first drill. But as you can see above I can at least swim a little bit. I really wish I moved through the drills a bit faster. The lack of diagrams.
