This webinar covers everything you need to know about swimming performance tests. From the test (protocol) itself, to the results and application.

Alexander Törpel (Head of Diagnostics – German Swimming Federation) talks about the application of test results in training. You’ll get unique insights into the (longitudinal) development of performance metrics, of 2 Professional National swimmers.

Agenda:

  • Swim Test Methodology and Protocols.
  • Test Results: Swim Performance Determinants.
  • Case Study of 2 Professional National Swimmers
Presented by
Alexander Törpel
Head of Diagnostics
Head of Diagnostics at the German Swimming Federation. Uses INSCYD alongside lab testing protocols to refine training strategies for elite swimmers, contributing to Germany's multiple Olympic medals in swimming.

0:00  um so welcome everybody again to this webinar good evening good morning good afternoon depending on where you are uh webinar today is about performance testing in swimming with um dr alexander turpel from the german swimming federation who is going to share some very interesting insights into you know how he uses the data of performance testing with inside that is the second part um of the webinar the first part uh also we know i'm going to take over and for everybody who's not entirely familiar with how testing with insight and swimming works um

0:36  that's what i'm actually going to going to talk about in the first 15 minutes 20 minutes approximately that alex is going to take over for another approximately 20 minutes and then we're going to have q and a as always at the end so with that i'm going to start um high level really um what are we looking at when we want to understand the performance of athletes in swimming there's many different metrics that somebody might be interested in in swimming very important you can see on the top

1:11  right here is economy so energy demand or how energy is translated into speed then because of the nature of the duration of the events it's very important to look at anaerobic or specifically glycolytic energy metabolism vrmx as a marker aerobic metabolism vautomax as a marker and then especially in swimming you have things like you know um aerobic energy contribution i'm just naming a few there's quite many more i also name recovery from high intense efforts that's obviously not really that important in a race but it's very important when it comes to training to plan um really like you know spot-on training programs it's

1:53  it's really helpful if if you can understand exactly the recovery times of your athlete and that's something we are going to touch only briefly on when we talk about training zones um again my idea today is is to give you a good understanding on what it means to assess performance of swimmers using insight and with that i would like to give um you know a concept on how the swimming speed um from a physiological metabolic point of view how the swimming speed that you're aiming to improve is actually created or how

2:35  different systems so to speak interact to create the swimming speed so this is at the end this is why it's in the bottom of the slide where you want to go right we are interested in the speed of the swimmer because this is going to you know win or lose us a race and then the first part one of the main important parts and i'm going to give you an example about this is how the the athlete is able to translate energy or power nothing that energy over time uh into speed so you could cause a swimming economy

3:08  that goes back to drag um therefore position in the water body size um or body form and obviously swimming technique so this all influences the translation so to speak from energy or power into speed so basically saying how we get through speed translation from energy into into speed now we want to look at how do we get the energy and very simple as you will be aware there's three different ways how a swimmer how an athlete can produce energy one is aerobic energy okay very very straightforward

3:42  and the aerobic energy is basically made up or as a marker you could use the view to max or the oxygen uptake for sub maximum conditions and then this view to max is kind of limited or influenced by what is the cardiac output so how much blood so to speak can the athlete pump from the heart to the arms and legs what is the perfusion how much of that reaches the muscle and then how much mitochondria or aerobic enzymes do you have in the muscle so high level a little bit conceptual how does you know the how is the

4:18  aerobic energy created and what does influence it and we're going to come back why that is important how that actually translates into into a practical application another not as important energy source is phosphocreatine or creatine phosphate not so important because to give you an idea for an 80 kilogram swimmer you're looking at approximately 11 000 joules 13 000 joules of energy which is compared to the other systems not a lot especially if you have to spend it not over 10 seconds but maybe over you know two

4:52  minutes three minutes four minutes or even an hour and this is primarily defined by how much muscle mass the swimmer is using and how much creating phosphate is per kilogram of muscle mass so that's not so much really here how you can do in terms of training it's relatively straightforward however what can be a significant contributor to energy and therefore power output in swimming is glycolytic energy and this goes back to the marker of vlmx you could say it's a glycolytic brother so to speak of the vo2max so

5:27  you know lactate as a marker for glycolytic energy production because for example when you use glycogen as a source um so you get 1.5 uh atp per per per lactate and then one thing that comes into play here is is buffering right because you know at the typical swimming distances you're going to max out so to speak with glycolytic capacity and therefore buffering comes into play okay now you can say okay that's nice but that doesn't really apply to practical application the fact that this does because most

6:05  of the stuff i'm showing you here is represented in inside and the stuff that's not yet represented is maybe already but it's not live or we're working on it so swimming speed obviously is something you put in and then the translation to the economy is something that goes in of course we will display for you the contribution of aerobic energy uh aerobic and anaerobic energy contribution vo2max and blamx is something that you get you're working on buffering capacity calorie output so on and so forth so what

6:35  you get is almost on all level of that you do get a good reading of those numbers based based on your inside testing okay and how does this testing work basically the testing works like um just on a high level to give you some explanation you have all these metrics in there and you start with the simple ones like body weight body height body fat and so on and so forth and i just put one screenshot here one example for this body composition body composition is in there so you enter either the body fat
