Amazing! But jeez Dave you could have looked a bit more tired at the end!

Ant's turns look interesting, most people kick off the wall so it's refreshing to see another stype that obviously works well.

Thanks Fran for putting up the vids.

Cheers,
Ben

Jeez Dave your style looks soooo relaxed! Amazing performance.
Thanks Fran for the vids. Any footage of the DNF performances?

[f3dive]

Adam,

Ive got all the footage! Mine all mine
AIDA NZ will be making discs available for purchase in the near future for those interested.

What? Making money out of freediving? I think you've hit on an idea there. Well sign me up for a copy.

Very interesting technique. I haven't seen anyone else doing that sort of "doble kick-then-glide" thingy.

Looks very relaxed but effective.

Dave, do you swim up in a similar way from CW or do you use constant kicking? Or different styles on different stages of the dive?

[Goran Colak]

I'm dooing that dubble kick then glide technique, and for me is quite efective... and I'm glad to se someone alse dooing it, aspecial when that guy is WR holder It's wery relaxed way to do DYN, but for me it's not posible to do CWT like that.... I'm interested what Dave will say!

I started doing the double kick glide method about 9 months ago when I got my Kershkov fin. I thought I was tricky and a revolutionist and all that, then I found out Wal Steyn was doing it in Aus and then when I went to a couple of competitions I saw tons of people doing it.... my revolutionist theory went out the window

I think it's probably the best style for that type of fin - kick glide doesn't work well for me as I don't get enough propulsion off the kick to glide very far (kind of stocky build... not very hydrodynamic), but a kick kick glide seems to work better, and my speed tends to still be fairly quick.

Wal suggested to me to use the kick kick glide on the ascent in constant weight and i've noticed this works well in the "middle" phase... ie. Turn on the bottom, couple of hard kicks, then slow it down for the kick kick glide for the rest of the way until I get closer to bouyancy.

Looking at Dave's vid he doesn't seem to need to use much energy in his kicks... damn these tall skinny b*stards... who told them they can freedive???

Cheers,
Ben

We all pretty much copied Ant - if you get to watch Kerian's video you'll see he's doing the same thing. Guy is also doing something similar except with a single kick. I've actually been playing with different techniques quite a bit and that was only about the 3rd dynamic swim I've done using that style (training included). Before that I was either 1. wearing a suit and heaps of weight, doing a very slow 1 kick & glide or 2. using no suit and a fast, continuous kicking style depending on what mood I was in. 1. is good for training because I can keep warm and do several long dynamics in a row without generating much lactic acid.

Don't consider this the last word in technique just because that was a long swim, I'm still playing around and I've been getting good distances with the other styles too.

It works for CW, but only in that 10m or so on either side of neutral buoyancy. I haven't tried it on the ascent. I do pause a bit in between kicks on the second half of the ascent though, more because I'm tired than anything else!

If you get good power transfer through your hips/knees without letting them go floppy and flex too much you don't need to move the fin far to generate power.

Goran - Nat Record only. Unless you mean Stig - he's using the same style these days isn't he?

[Goran Colak]

Oh Good... i just now realize that this event was no WR status event, bad luck Dave... I all the time think this is a new world record

I think Stig is doing one kick then glide if I remember corectly from Maribor...

One question for you Dave, that DYN svim was in 33,3m pool... Why? Is that lenght of the pool that fits you guys the best or? I just thinking, if I made 234m in 33m pool I will do at least 250m at 50m pool.... Or that is just me and my slopy turns

[Mullins]

Turns take quite a bit of time/energy so I much prefer a 50m pool, but there aren't many around here. The next competition we have in Wellington will be in a 50m pool.

[Goran Colak]

Hope that will be WR status event...

[f3dive]

That pool produced Walter's 201 metre swim in June last year so it's seen 3 200 metre+ swims.

I tried the kick kick glide tech. today for the first time. my primary exposure to technique right now is youtube so up to now PeterPedersons200m has been my model, noticed the glide style first on the maribor men/womens dyn and now with the amazing performances in new zealand. anyway had a few questions-
-I'm using an older style WWmodel1 med.stiff a single kick/glide doesn't seem to work so well it tends to stall out or sideslip when I initiate the undulation after the glide, which doesnt happen with constant undulation.
-The double kick seems to work extremely well, but is far from a smooth transition after the glide, was nonetheless very pleased with the results
-Noticed most people doing this are using Hyper/Glide type fins are these much better suited for this tech. Is there anyone out there doing it successfully with an old fin. Is it the fin or will practice work out the deficiencies
-any tips appreciated, excited to see how this tech. develops

Using a waterway glide fin, and no wetsuit, FRC, in constant weight, I use the kick/glide on the ascent. Obviously I don't do any kicking at all on the descent. With no wetsuit and only a tiny amount of air in my lungs, my buoyancy remains at a virtually constant level (sinking at 0.75-0.85m/s). This is the same speed seals sink at and I find it optimal. The unchanging 'negativity' in FRC no suit diving allows the use of the kick & glide method for the entire ascent. At a 'negativity' equivalent to a sink speed of 0.75-0.85m/s, I cover about 2 - 2.5m per stroke on the ascent with the kick & glide. (In dynamic I can cover 5-6m per stroke).

According to my personal experiments & calculations, I feel that the next generation monofins give a greater advantage to FRC divers rather than packing divers, for various reasons.
