Freediving training @ the tongelreep’s 50 meter pool

[gravatar size=18 align=absmiddle email=sanne.buurma@gmail.com] This is a post by [the_author_posts_link].

Last night I went out to the Tongelreep for some freediving training as it’s thursday again. Jorg only just got back from holiday and pointed out that he would be joining again next week, but both Kostas and Yugyug were there to join me in training.

img_3893I didn’t really set up a schedule for me to work on, but I did want to do a few crawl without breath’s, DNF’s and some static at depth. Unfortunenately the Tongelreep was on summerschedule, so the 5 meter deep pool was not available to us at this time. We had to switch to the 50 meter official competition pool section to do our training. This is the section also used with the dynamic’s during the 4th dutch Apnea Open. The pool is 3 meters deep and has a lot of lanes available, but it’s rather hard to get a lane to yourself » so you’ll always have to be alert to swimmers going about their own business.

So Yugyug and I agreed to start with some warm-up laps, which for me meant doing about 4 lanes of 50 meter crawl without breath. Yugyug was doing 25 meters of DNF’s to get his system prepped. After our warm-up Kostas joined up with us and it was time for the static’s at 3 meter depth. Yugyug and Kostas did really good static’s and I got inspired to do a static as well. I agreed with Kostas on their tapping strategy and told him I would see how things progressed but I set the max to 3 minutes. This all went really good, I wasn’t all that relaxed as the last time with Jorg I had a good 3 minutes at 5 meters, but in general I did not have a hard time taking the contractions for the last 60 seconds.

After the static session I had a go at DNF’s over 50 meters, which had been a while in a 50 meter pool. First lap was progressing good, but confidence was lacking a bit so for safety reasons I went up at 40 meters, as I was training alone at this moment.  But after resurfacing I instantly could feel and notice that this safety measure altho good to do, no where near any out of breath signs ;). So as confidence was up again I started at the other side and did another DNF run back and this time the 50 meters went away easily again. Although touching the wall at 50 meters did feel as a relief, I think that’s only due to the fact I haven’t been doing this at all lately.

20081217_Technique_DYN_Kostas_01Kostas decided to go for a DYN over 50 meters after he first tried 2 x 25 meters to warm up. He came up easily, but one of the things to note here was that he’d decreased his swimming speed and now did a dynamic over 50 meters in about 1 minute 10 seconds, which he said did make him more comfortable. We’ll see how this progresses over the weeks to come.

Overall we had a quality training, learning a lot and having fun. I’ll try and write an exercise post about the crawl without breath to give more insight in this good training exercise. So stay tuned.

Finning technique (DYN)

The equalization that looked very promising last Wednesday, turned out to be the thing Kostas had been missing out on. He was able to equalize on land during the last 7 days and was eager to get into the water and test his new ability. So I brought a set of weights to the pool and let him drop down to the bottom with it. This way he could focus on only his equalization, first he tried head up and after that head down equalization. This all proved to be no problem anymore and in a way he found what he was looking for when joining us in the first place; Equalization.

Finning technique (DYN)
20081217_Technique_DYN_Kostas_01.jpgThe equalization was pretty important for the finning technique in the pool. As I wanted him to test his buoyancy by varying his air intake and depth, we weren’t able to vary the depth’s because equalization was in the way. Now he could vary his depth and air intake to search the neutral buoyancy to test with.

The fins we started out with are the C4 carbon fins, as they aren’t as stiff as the GARA’s. Because the legs aren’t making the proper movement yet, I think this is a better way of getting your legs to move the way you like.

As always when we’re trying to improve certain aspects we capture all dynamic runs on video and look at these video clips after every dynamic run. We’re currently only focusing on his finning technique, so push of and other parts are not in the way of Kostas’ focus.

Analyzing the videos
From the videos Kostas and I concluded that the knee bending was a thing he needed to think about in the next runs and I told him to really exaggerate that there is no knee joint. After a few runs this seemed to have the positive effect. Although his left leg seems to be somewhat better then his right leg, overall progress is huge al ready.

Other points he has to work on is a fluent movement and the wiggling /cork-screw-motion. Of course these are difficult to get rid of after the first time, but as determined as Kostas is he wants to get rid of this and further perfect his technique. Take a look at this compilation:

Your opinion?
What are your opinions on his technique, what do you recommend him to be working on?

Just leave a comment and I’ll be sure to pass it on to him in the next training.

Equalize it

20081123_DutchApneaOpen_02.jpgWednessday evening Kostas and I went out for a dynamic technique training. Kostas had to focus on his finning technique and I was trying out the speedo breeaststoke fins to test a DNF question from Eric van Riet Paap.

What I noticed with Kostas was that he was floating upwards while trying to improve his technique, so I stopped him and said he’d be better of trying to swim a little deeper with a whole lot less air intake, because we didn’t have any extra weight to drop him straight down to the bottom 😛 . Before I could get him to swim deeper, we still had to solve his ability to equalize.

Equalize it
What seemed to be the trick into getting Kostas to equalize is that he was not using the pressere in his nose to equalize the ears. Although he was trying to put pressure on his nose, there was no air to compress and built pressure, so the effect was zero. After I checked for myself what I was doing whilst I equalize, I gave Kostas this tip of building pressure with air in his nose. After he tried it once…he heard a popping sound for the first time in his freediving experience. He was now convinced about the technique and knew what pressure to build to hear a popping sound. Welcome to the world of equalization Kostas !

Next week
Now he was able to equalize he could focus on his technique in dynamic with fins. His appearance in training at depth was very relaxed and unlike before ideal to focus on his technique. I guess he’s going to be very eager to go to the pool again next week.

4th Dutch Apnea Open

dutchapneaopen.jpgLast weekend Immersion organized Dutch Apnea Open in the Tongelreep Eindhoven. Together with Kostas and Guy, I participated in the competition, Marieke and Jorg were there to coach us along with friends who dared to travel through the snowy weather.

As it was the first competition for both Kostas and Guy,we had practiced the rules and procedures on the Thursday before the competition. It was a good training and new ground exploration for both of them.

20081123_DutchApneaOpen_02.jpgArriving at the competition we looked up our Official Top times and whilst doing so you just always bump into all familiar faces. Nice to see such a large competitor field. Talking to fellow freedivers and friends filled the first hour at the competition.

After all the socialization I got to coach Kostas and Guy for their performances in static. so we agreed upon our safety-tapping strategy and set out the planning for a small schedule until both their OT’s.

Static sessions
Guy Keulemans
20081123_DutchApneaOpen_03.jpgAs the organization set up the lanes somewhat confusing for freediver participating for the first time, Guy showed up in the wrong lane. As Guy was preparing I saw the competition field being entered by an other competitor so I had to relocate Guy into the proper lane after which he was ready to do his static. Not totally relaxed, but confident he did a great performance of 2m 39s. Not topping his personal best, but usually that’s a hard thing to do in a competition.

Kostas Kevrekidis
20081123_DutchApneaOpen_01.jpgAlso Kostas showed up in the wrong lane and after relocation we got to do the warm-up static’s. Eager to go for his static Kostas did his warm-up dives properly and prepared for a very good static. Having no problems while his goggle straps almost sprung just before his OT, he didn’t really had to struggle to get a perfect 4m 36s static.

Dynamic Sessions
Kostas Kevrekidis
Not totally confident about performing a 50m+ dynamic with fins, Kostas prepared for his DYN with a warm-up dive of 50m’s, no problem at all! So Guy and I inspired him to just do a turn and a few kicks and then he could still see how he felt. That being said he started his DYN and almost got stuck in the 1st meter start line, not distracted by that fact he went for 50m’s and turned. The 2 or 3 extra kicks got more and he did a great 85m DYN. Slipping up the surface protocol made it a disqualified performance, but does nothing to the fact he really made a good effort and perfect distance.

Guy Keulemans
20081123_DutchApneaOpen_04.jpgGuy prepared a schedule preceding his OT for DNF and the warm-up statics proved to be helpful. As the 3m deep pool posed no problem, he did a perfect 86m dynamic without fins (DNF). Seeing all the technique from our training put into practice and the points of attention for the surface protocol all went flawless.

I’m very proud of both Kostas and Guy for showing good performances!

Guy put up his pictures and movie-clips in this gallery » click here…

So…What about yourself…?
As for me, I’m currently going through a phase where I think it is best to resign from competitions for now. The pressure I put upon myself in wanting to always show the rest a worthy performance, I forget to enjoy competing in competitions like these.

For the record; my performances:

  • Static: 3m 35s, the point where usually my contractions come and the first fight starts.
  • Dynamic: 70 m DNF, clean and comfortable and yet again to the point where contractions and the fight start.
