My Video’s from the Liege competition

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

Last night I edited the video material we shot at the Liege competition last weekend.

The first video is Dynamic with Fins (DYN), a first timer for me at a competition to use a monofin.

The second video is Dynamic No fins (DNF), especially focussed on technique and minimal amount of strokes to reach 25 meters.

Although my mission was to reach the 25 meters in 2 strokes, the positive buoyancy made it harder to accomplish. I took 2,5 strokes for 25 meters, but the speed is still at the level I like it to be.

Enjoy the videos.

Video: Bizzy Blue Hole 2008

Last year’s Bizzy Blue hole competition was a successful event for me. I’ve set new personal bests on 3 depth disciplines; -40m in CWT, -35m in CNF & 33m in FIM. Marieke made some excellent footage of these freedives and I found some time to combine the footage with the results from my D3 freediving watch.

These are the statistics from the different dives (keep in mind that the data shown below is from my own watch not the competition watch. The competition watch is attached to the wrist reaching for the tag.)

High Definition Video testing

puredigital_flipminohd.jpgLittle over a month ago I purchased a nice little gadget which lets me record in High Definition quality (720p). The gadget is just as small as a phone and weighs even less. It’s a Flip Mino HD and it brings mobile HD video to your doorstep. So the perfect opportunity for me to test it and thus I’m bringing it to the freediving we do.

Check out this small video clip in HD ๐Ÿ˜‰

This is just a short impression clip we shot during the last 2 training sessions (The last run of 1m 30s static schedule of Indoor & Outdoor freediving in Bosmolenplas, Panheel), so far I think the FLip Mino HD can bring us that extra footage we can use in our video clips ยป enriching the freediving experience like we do in the moment.

Now all we need is a underwater casing for this small and mobile HD recorder, as they only feature an underwater casing for the Flip Ultra.

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.

Speedo – Breast stroke fins

Last Thursday I already took my new Speedo Breast Stroke fins for a test run. I was actually surprised by the amount of propulsion it produced. I did a few 25 meters DNF to see how propelling with my legs was exaggerated to a level I became aware of the way it should feel.

As I’m still finding my way through the proper technique and the helpful tools to get rid of my scissor-like leg movement, Kostas joined me last night with another helpful tool; the video-camera. Looking back at the footage right after I did the 25 meter test runs, made it more obvious I needed to lower my right leg even more.

As a comparison we made a few clips where I did a run with:

  1. initial technique without the speedo fins
  2. corrected technique without the speedo fins
  3. initial technique with the speedo fins
  4. corrected technique with the speedo fins
  5. corrected technique after use of speedo fins

When reviewing the footage some interesting facts grabbed my attention. In relation to how it felt whilst doing the different test runs, I can say that even though you wear the fins, I still need to be paying attention to the lifting of the right leg. When applying the force with the legs, the moment of ultimate propulsion at first seems to be short. But after re-capping the things William said in his course you can keep the propulsion going by scooping more water, by pointing the toes inwards at the end.

My scissor isn’t gone by long, but getting aware of the fact by reviewing the footage is very helpful. Another thing which makes me aware is by looking down at my legs whilst swimming… it’s not the most elegant way, but then I seem to see the errors and correct them instantly.

The next few weeks I’ll be swopping between my DNF-technique and the DYN monofin technique.
