UWH Athletes and the international standard

"Language: Eng"

Are you sure this was english?

Wot?
Does that article suggest that UHP just act like divers. So what?

Believe it or not, this is a big deal. Freedive training enhances the diving reflex significantly, while I had assumed that if anything, UWH training would do the opposite. The fact that UHPs still had a strong diving reflex suggests that heartrate under the water is lower than expected for the activity undertaken, which means hockey players are trading longer apneas for higher lactic loads and slightly longer recoveries. The higher ppCO2 means that like many top freedivers, you've (probably accidentally) discovered that higher aterial CO2 concentrations enhance the diving reflex, allowing longer apneas with a lower chance of sudden blackout. It probably also explains why Stella kicked arse when she did some serious freediving training.

If anyone's interested, I can post the DAN report on breath-hold diving. It's a bit of a monster, but there's some amazing stuff in there, like Umberto's recorded R-R heart rate frequency of 9 bpm @ -50m and Tanya Streeter's experience with narcossis at -160m.

post away, would love to read it.

It's a bit of a monster at 173 pages, so it's on mediaFire for the moment.

Carl: If people find this interesting, would you be able to give it a permanent home on the server somewhere?

hmmm, that is rather large.

Well, South Africa is a long way away for most of the teams, so I suggest the athletes take a copy with them on the flight. If you're interested in it, you'll have something to do for a good 10 hours and if you aren't, the scientific bits should turn the most dedicated insomniac into a chronic narcoleptic.

That's the most useful advice I've ever heard. I just might bring it on the long leg of my trip, DC-Johannesburg 14-15 hours flight time, 21+ with time difference.

I finally read that paper after having cleaned off my desk and found it under all the other ones I hadn't read.

Sadly the study probably can't tell us anything because they've compared elite UWH players to students who don't exercise more than 5 hours a week. So anything that you do (or don't) find could associated with UWH training or it could just be training in general. The authors do claim, however, that the control subjects were as fit as the French national underwater hockey team on the basis that the maximal output (VO2 max) was not statistically significantly different. This lack of significance could be due to small sample size (10 versus 10) as there is an apparent difference between the groups of about 5 ml/min/kg.

So I'm afraid I didn't really get much of a take-home message for any of you.
