Static time vs CWT time

[Gwolla]

Hi all,

I am curious to what is your difference in PB time when u do a static compared to when you go CWT (max personal depth).

For me it's,
Static: 3.05
CWT: 1.25

I'm not really a trained person, nor on any special healthy diet, so the question is basically to see the difference it makes when you do train and follow a healty diet.
I'm aware the relaxation underwater plays a huge role aswell. So please also comment whether you feel you are optimally relaxed on the CWT or not.

I myself feel pretty close to the same relaxation in static when I close my eyes (just holding the guideline for straight decent). With my eyes open its a tad harder cause of the line visualities (has some stipes on it and I can't keep the same constant speed apparently so it gets fuzzy in my head after some time).

CWT and static are in many ways opposites. Many things just don't seem to add up and I don't think anyone has all the answers yet. One of the most interesting tests done showed that a trained diver surfaced with more O2 on deeper and longer dives. Doesn't make sense to me how that can be possible. You have to train both but there is some 'carry over' from static to constant.
To answer your question, 8:05 and 2:35. I've also done a four minute Free Immersion to 60.

Bill,

Am I right in assuming that your CWT time was limited by depth and equalization not by your breath hold though ? Also your 4min FI I'm assuming was intentionally slow ?

Thanks,

Meir

I think it would have a lot to do with the diver's DR and work response, which are fantastically individual. I have not been able to test accurate my O2 use on deep dives but from testing I have done in a pool and facial immersion, etc, I can definitely see this happening. My DR kicks in fairly well in the ocean where I dive, usually very quickly once I start to freefall (nearly minimal exertion). Once established it stays pretty solid even when I start exertion (kick to surface, crawl on the bottom). From testing in a pool wearing an O2 meter and doing sprints or just faster than optimum swims, I get a little response but no where near the same thing as a super slow swim; in a pool I def end a slow dyn with more O2 than a faster one. Like I said, I have no way to test in the ocean but I feel much more hypoxic on a touch and go dive (like pop down to grab a piece of gear) where I am never fully relaxing than on a longer dive which may ultimately be deeper and longer on the clock than the other. I will incur greater lactic penalty on slower dive though since vasoconstriction, once it starts, stays until I start to breathe again at the surface.

My PBs were both limited by sand but the CWT was a one-in-a- million, a long time ago. Up until the volcano fired up (1000-2000 tons of SO2 per day, 30-40 miles away) I dove 2 or 3 times near max every week. Now everything, especially static, has been limited by VOG for years. When I was forced to slow down in CWT (3 hip operations), it cost me about 10% in depth and when I slowed my FIM 20% for sticky sinuses the max depth stayed the same. The more I learn, the greater my befuddlement.

Thanks for the info. I'm curious as to what would happen if you swam the DYN a little like the CWT. Try as fast as you can for the first 10 meters and see what response that triggers.

Bill,

Thanks, you da man !

I need to get something that accurately samples pulse underwater (like a Galileo) to do these kind of tests more effectively but I am pretty sure if I did for instance a 50M DYN swim in warm pool water, sprinting the first 25 meters, I would get a DR that was delayed until my pulse came down from the sprint, so perhaps towards the end of the 50 it would start to kick in, or it might never really have the chance in a 50M. I get the strongest DR in the pool if I start very slow. I have done it the other way around, and tested pulse--where I went very slow for 25M and then sprinted the last 25M. In that instance my pulse at the end was less than normal resting but higher than if I had done the entire 50M very slow. One thing though--DR in a swimming pool (warm, shallow water) doing DYN does happen for me but it fades with repetition.

I could try the testing with cold water facial immersion and see what happens--sprint pedaling for the first 20 seconds of a facial immersion, followed by low effort perhaps.

I don't really compete or line dive much but for vertical and deepish spearing dives I typically swim at low effort until I reach neutral/freefall, and from then on typically work at a zero to medium effort. This profile for me definitely feels better than a fast down. And when spearing in warm water (typically doing 70'-95' dives), it is definitely better for me to wear enough weight to be negative before I hit the bottom--reduced down effort when compared to the same dive with no weight. By better I mean longer dive time with less hypoxia on surfacing.

Of course, this is just me and where I seem to fall on the spectrum of DR and work response; doesn't work this way for everyone...

Sorry to hear that Bill, must suck thanks for the info tho. I realise its 2 different things. However for as a relative new freediver I feel the 2 are more related. The more I train static the more I feel it is helping me in cwt. So now I am more relax in cwt cause of the learning of the lungs and pretty much how everything works. This is a learning of static practice ofcourse. Learning oneself must be most imprtant for the sport.. The times indeed may not be relevant, but for me answers seem to be important.

Myself I prefer slow kicks at start, feels more natural and relaxed.

I think its all very individual. in my case pool never translated well to the ocean no matter how strong i was doing in the pool only time in the ocean improved my performance there. not that the pool didn't help with strength muscle memory etc.
