Strange Static

[O'Boy]

Hi,

I experienced this kind of static 2 years ago while competing at my first freediving competition. Since that I've become more skilled in dealing with competition stress but...
there's what hapenned to me last weekend (II.AIDA Slovak Champhionships):

- warm-up as usual - pack stretching, pranayama, 1'15" Exhale, 2'30" Rest, 1'50" Exhale, 5'00" Rest
- 6 Packs + GO!
- there was extreme drop of heart rate right after the immersion
- Contractions came at 1'30"!!!
- it ended after 54 contractions with a Samba at 5'02"

My PB is 5'45" (@2'55", 35 contractions, significant HR drop 2'30")
This is what my common static looks like. My HR keeps somewhat elevated(85 Bpm) untill 2'00" and than it falls under 45 Bpm and decreases further.
Even when doing static without Warm-up I don't get contractions sooner then at 2'00".

We all know that competition stress decreases bradycardia so I don't understand what hapenned in my case. Could the fact that I was using no wetsuit and the water temperature was some 25C be the cause for such demonstration of diving reflex? I felt cool but not cold.
Why such soon breathing reflex after 5'00" rest and prior 1'50" Exhale static without contractions? Could the cause for contractions in this case be drop of PaO2 rather then increase of CO2?

Have you ever experienced such static?
Thanks for your answers.

I think the temperature had a lot to do with it. I have done statics (and dynamics) where I felt cool but not very cold and they followed a similar pattern. After a short time there was a very strong urge to breathe, which increased much faster than it normally would. This usually put me off and I finished early. If I decided to ignore this feeling, there would be big trouble.

I'm sure that generating heat burns O2 very fast, and the cold also makes some people much more likely to samba while their O2 is still relatively high compared to their PB.

I hope this is useful
