Turning techniques durin dynamic apnea

[iparcell]

I have recently got fins and although the speed me up much more and allow me to use less energy at the same time. im am still only doing 5m more than without fins . i think the main reason for this is that when turning at the end of the pool it takes much more time with fins then without im just looking for some of your turning methods
cheers,

Try not going straight in but doing a broader U turn with your side towards the wall.

Or go straight, but twist around so you are almost on your back just before the wall, that way it is easier to push off in a forward direction.

Let us know how it works for you.

I dont do dynamic apnea as my main sport and use it mainly as training, but am I correct in assuming your not allowed to break the water or else the dynamic will be considered finished. What about using a swimmers turn, coming up off the bottom enough to be able to dive down and turn and kick yourself off the wall again...

Swimmer's turn is usually not efficient at dynamics with fins because of the suction effect when pushing the wall with your feet. There are different techniques used in DYN, but mostly people indeed use the U turn Evita describes. I recommend looking at couple of freediving videos - you'll get the idea. Check out my video collection - you'll find many DYN videos in it.

EDIT: for example the videos labeled "Faire de virage" on the page travail dynamique are excellent:

Gonnie Roekevisch (NL) shows quite funny technique of reverse turns in this video from Freediving - Apnea Team Amsterdam:

You can break the water within 5 meters from the wall, so you can break the water during a turn. By swimmers turn, do you mean a crawl turn? I have seen freedivers do that with a monofin, flipping it clear of the water in a salto and smacking it against the wall for push-off. It looks awesome, but also quite exhausting. I wouldn't do it...

[deep thinker]

Exactly what I meant Evita, but I do think with practice it wont take such alot of effort and I thought it mite save on time. But hey like I said, I use dynamics only for training purposes and if I do turn Its normally a lazy u turn not even pushing off the wall for distance, so I guess Ill leave it to the competitors to do that bit...

[Evita]

I think you're right about saving time with the salto turn - the competitors I have seen doing it were high-speeders and explosive in the water, so this turn suited their style really well. I go really slow and I am too lazy to bother with a high flip of the fin

thanks guys

do you use the same techniques with monofins?

Again, different techniques of turns are being use with monofins too. As I already suggested, I recommend watching some videos of top competitors and comparing their techniques.

Using a flip turn (competitive swimmer type) with long fins can work pretty well for dynamic. You flip and heels hit the wall very near the surface, fin blades in the air. Looks bonkers, but allows a strong push off with no suction effect. You don't try to rotate to belly down until after the push off. I use it off and on. For me, It isn't very relaxing, just a good change of pace. If your style of dynamic was fast, it might be a good choice. It gets much easier with practice. Probably not worth the trouble for a relaxed style.

Hi Trux, cool site on the video links you've done! Thanks a lot.

It seems most people use the slow relaxed U turn. Does that apply to monofin too? Any clips you know of showing the monofin turn pls?

Hi,
check out the video of P.Pedersens 200m record, there u see the turn with monofin

[Kaspermoth]

try to avoid to break the surface, it will evidently create waves=energy loss.

I do a variation of eva's U turn but I lift my knees to my chest while doing so. My idea is to minimise the radius of my body mass and by that having to pay less energy for the rotation. Disadvantage is that I have to move my legs slightly more, of cause that cost something too.
