Last time I wrote about the results of Sanne during the AAAC 2007 competition I analyzed his static performance and things to look for. Now it’s time to look at his dynamic with fins performance of that competition.

First of all take a look at the performance of Sanne where he does a clean and easy 108 meters, which is his first dynamic with fins since 6 months.

And now let’s start with breaking down all different aspects of the performance.

The part that is not in the video is the preparation part. This time I leave this out, because it’s part of our total philosophy how we train at Shark. I already wrote about that before and I will make a separate post about that later.

So in this case preparation starts in the pool. We see Sanne squatted down in the water breathing in and out. As the pool is shallow you have got an opportunity to have an excellent breath up by standing straight in the pool, so that your lungs will be out of the water. This way there is no pressure on the lungs and you can make a very easy and full breath up. As soon as your lungs (or stomach) go below the surface there is already extra pressure which makes breathing in less perfect. Last breath is without packing, which in Sanne’s case is okay for now.

The time of the start is good, only 1 second after official top, exactly how we train it. So in case you miss a breath or something doesn’t feel right, you still have time to take another breath. The start itself is not as good as it should be. At official top Sanne is still in complete squatting position and he has to put his feet/fins back against the wall to push himself off. Both fins break the surface. Next time stand in standing position, only one heel against the wall in the end. Drop yourself straight down under the surface. Change the angle and push straight ahead with only one heel against the pool. Arms in front during the start and bringing them back in the first moment of the push is hydrodynamic-wise not as smart, but it feels great. We will do some tests to show the difference and to sort out how we will continue.

First lane goes pretty well. Posture is okay. Head down and no looking forward. Arms by the side. Kicking style is pretty okay, we now what to work for and what to improve; no side movements in the kicking. Also the end of the first lane where you get in deep part goes pretty well, no dive in to the deep, just going straightforward. Total time for the first lane is 42 seconds with 30 kick cycles, which makes 42,85 kicks/min and 71,4 mtr/min.

Turn at 50 meters is just shit, but as Sanne explained to me there was a ridge at turning depth which he couldn’t touch according to the rules. We see this is many pools, but the height on this one was not so good. So both fins out of the water and a lot of energy lost by diving down again and getting under the surface. With this you automatically dive down to deep in the deep part of the pool. Total time for the turn, as planned, 2 seconds.

Next 50 meters we see a clear increase in speed. Style stays more or less the same, but the speed is much higher. Also as mentioned in the last paragraph, Sanne is too deep at the beginning, and this way he bumps up against the floor that goes up. Time for that lap is 3 seconds faster then the first 50 meters 39 seconds. Total kick cycles are up tot 32, 2 more then the first. So we have 49,23 kicks/min and 76,9 mtr/min which is a clear increase in kicks and distance. Is this good? We have to test it out, but previous tests show that Sanne has a lot of power left in his legs at the end, and why not put it to use. All in all, some extra stuff to look into. More on this later.

Turn at the 100 meter mark takes another 2 seconds and the heels are coming out of the water again. So a slightly deeper turn (if that was possible in this pool) and more horizontal body would for sure make it work.

Last 8 meters are done in 7 seconds with 5 kicks. Not important to make a kicks/min or mtr/min calculation, because it’s the last part and it’s short. It’s interesting again to measure this if have more then 20 meters, otherwise the numbers just don’t work out. Especially with the last phase, where you let yourself gly and come up.

Surface protocol is again way to fast in only 7 seconds, but I’m getting used to that with Sanne. It’s time that he put some more effort in it so he needs at least 10 seconds before he starts the protocol. Anyway, this convinces me that there is a lot of room for improvement.

Total time of the dive is 92 seconds with 67 kick cycles for 108 meters, 88 seconds of pure moving dynamic time and 2 times 2 seconds of turning time. If we take this number and compare it to the rest of the measurements we did to see what’s possible, the numbers show that Sanne is for sure capable of doing a lot more. To be precise Sanne should have no problem with doing a 2 minute dynamic at all which makes around 140 meters. So why doesn’t he do that? That’s a story for next time I’ll write here.
