First small no-warmup frc static success and no-goggles dynamic.

Yesterday in the pool I did a frc static of 4:02 with no warmup. This was the first time the no-warmup felt like a success. I had a good fight-phase and my safety told me I had no visible hypoxic signs at all.

On one of the other holds I improved my pool personal best to 4:18 where I found the surfacing a bit so-so but again my buddy told me that after one breath I looked fully recovered. During these other frc holds I noticed that I got progressively more relaxed when the contraction came. During the initial hold they were quite violent.

Nice!

After the 2 hour static of which about 1 hour was spend socializing we went to the other area where we do our dynamic training. Here I did my monofin training with short fins and a couple of 50+ meters no-fins, no-noseclip, no-goggles dynamics. These were just to get a feeling for it. I've done dynamics without a noseclip (but with goggles) in the past and in general liked them. The problem was that I lost some relaxation because water enters my nose and I have the urge for blowing out some bubbles. Swimming without goggles I have done very little, but since I do my TLC statics also without goggles I fear the stinging pool water less now. I was afraid for bad turns but that was no problem. Keeping the correct depth was a bigger problem but maybe with some practice that will improve. There is also the problem that at the end of the swim there is one less sensor to indicate hypoxy but that need not be a problem when I keep listening to my body. The dive reflex kicked in early - contractions start early at about 10-20 meters but this will be later once I relax a bit more.

If all goes well I want see how this goes during a small competition beginning of june.

FRC statics and depth training

Here in The Netherlands there are not many lakes over 30 meters deep. The deepest one I know of is 52 meter deep. My max. depth so far is just 43 meters but with the recent successes in the pool I'm sure I will go deeper not to long from now.

Inspired by Eric Fattah's very impressive FRC dives at the Vertical Blue competition in the Bahamas I decided to practice my equalisation skills a bit more by dives on half full lungs the next period. Last year I did 21 meters on FRC and this year, with more ease, I equalled that plus I did 28 meters where I'm not sure if I took the exact same amount of air with me. Anyway, making progress with equalisation and having much more relaxed abdominal muscles and diaphragm.

I have done some FRC statics to get a feeling of where I stand at the moment. These are some stats...

FRC static dry
1 exhale:
2:56 83% SpO2%
2:52 87%
3:07 83%
2 exhales:
3:13 82%
4:20 74%
1 exhale:
4:05 73%
3 exhales:
4:32 64%
2 exhales:
3:40 75%

FRC static in the pool (SpO2% unknown)
2 exhales:
2:30
3:45
4:11

So 4:32 dry, 4:11 wet.

Yet another day at the factory

Yesterday I did a couple of alltime low FRC statics. I think the best one was about 2:30. At least better than if I would not have done any.

8:01

So there you have it, I did an 8 minute static in competition for the first time last sunday. For me it did not totally come as a surprise because I did my first one in training about 6 months ago. But recent training did not go according to plan during the last few weeks before the competition. For this reason I took a week of from pool sessions. I did a little dry CO2 and O2 training but not much.

I was standing on the shoulders of giants because of all the tips and help I got from people around me and on the internet. Even so, for me personally this is a milestone I am very happy with. So I would like to put some more info on this blog that might be useful for other freedivers.

Some people asked what my preperation was and how the static went, so I will write about that here.

good night sleep
9:00: breakfast - two bananas and one bowl of yoghurt with honey
10:00: 2.5h car ride to Belgium, was drinking lots, mostly tea and water.
13:00: settled in the pool, relaxed a bit, chatting with fellow freedivers
13:30: be safety for Erik
13:45: be safety for Daan
14:00: kept drinking spa/water
14:09: start pack stretches
14:19: put my suit with 4kg weights on
14:24: deep breathing about 4 breaths per minute by the side of the pool
14:34: enter water (27C) empty lung (RV) static ~1:30
14:38: another empty lung static ~1:45 (about 50% of max)
14:40: 2x30s statics to find good amount of packs (tried 15 and 19 packs)
14:42: go to competition zone, normal breathing
14:43: 6 deep breaths during one minute (yes I know: hyperventilating)
14:44: tidal breathing, put noseclip on (no mask for me)
14:45: Official top (exhales, inhale, exhale, inhale, pack 15x)

Room for improvement here would be threefold.

1. stop hyperventilating for OT-2 till OT-1
2. don't do the empty static warmups anymore
3. one less exhale before OT

The static went pretty much as usual except that because of the lack of food in my system contractions came a little late at 3:45. My focus, determination and intend were better than in training. The first 30-60 seconds I was forcing myself to not influence my muscles. Trying to relax and see what my body would do, not identifying myself with either my body nor my thoughts. Usually I try to wait for thoughts and emotions to come, when they come mark them as 'thinking' without judgement and wait for the next event. The 'problem' I found with that is that at some point the words thinking, thinking, thinking quickly after each other start becoming heavy, like a hammer on a nail. This adds another layer. I then have to notice my noticing thoughts and let that pass. Maybe this is where true mindfulness starts but lately I found it works better to use some self-hypnoses instead of just the word 'thinking'. So what I did is tell myself in a way similar to talking to a little kid (I don't know the english term for it so that's why I describe it). I say (in dutch) "think slowly... slowly... and quiet...' Of course I say this slowly, firmly, matter-of-factish and as much as possible without stress. After doing this many times I arrived near 7 minutes, at that point deciding to better my n.r. of 7:33 and after that one (15 seconds) tap at a time. 8:01 was just about doable. I've been told that only at 7:30 contractions were visible which I find good because it also means that I was not mentally trying to influence them. At 7:45 I was aware I let out a few little streams of airbubbles. Since I was aware and clear-minded enough I allowed myself to pass 8 minutes.

For the first time in competition I did hook-breathing during recovery and I had the feeling that this did not yet automatically go as good as should be. More max attempts in training are needed for that. So two hook-breaths, two recovery breath, noseclip of, ok-sign, 'I am okay!' and wait for the result. I did not see a white card being shown to me, my safety (Daan, thank you!) told me and he was even happier than I was. My mind was not ready to let the outside world in just yet, that took another 5 minutes. (good times)

A movie of the last part will be on youtube soon.
