Did I "Bonk"?

[Cacia]

So...the other day, I dove the Corsair, and thought I dove to my NDL. I began my ascent at 0. (110 FT) I was in bed for 24 hrs from fatigue, no pain. I started thinking about Johnny P., my partner, having some deco and how I thought we dove similiar profile. So..I checked my Suunto and had a dive time of 36 minutes. I was on air.
On the boat, my cohorts were laughing commenting "Are you really THAT cold?". I had been very still, taking pics from one spot on the bottom and wore an old 3mil...more like a 2, max. I began shivering after being on the boat for ten minutes, until about 40 minutes later.

Do It Easy is so smart...wish he would post more. When I described the whole thing, the first thing he asked was "were you cold"? I have been reading a lot lately about "bonking" on the cycling forum. Evidently, if you deplete your glycogen stores, it takes about 24 hrs to recover. He suggested it could have been this...as opposed to decompression phenomena. My symptoms really fit the descriptions I have read.

Anybody have any experience with this?

I've never been bonked

Sorry....I thought we were talking about something else.....

Could still be sub-clinical DCS, I'm assuming if you were on a Suunto that you didn't spend 36 minutes at 110 fsw (that would definitely bend the computer, I've done 30 minutes at 90-95 feet on 32% and gotten within 1 minute of my NDLs with it). But, still, that seems to be pretty aggressive, I think the NDL time for air at 110 is what, 15 minutes or so?

Given that you were very cold, your circulation could have been reduced, and off-gassing could have been slowed. Reason I bring this up is that I've heard of individuals who got bent when abnormally cold, so it is something to consider . . .

Speculations, all of this. Glad you are feeling better, however.

[EDIT-I see the 36 was total dive time, not bottom time . . . my bad]

What was your dive time? Not your total dive time, eliminate the assent time.

Did you eat before the dive? And if you did how soon before the dive?

I've been lurking around here for a while now, and finally a question that I think I can contribute something to.

My other pursuit is endurance running. From marathons to ultras -- 50 milers, 100 milers, 24 hour races. I still run these races but no longer really compete. I do have way too much experience with bonking.

I'd have to say that the odds are that this is not what happened. Bonking referrs to what happens when you burn through all the fuel in your system, the glycogen in your bloodstream. This means burning all the glycogen that is available plus overrunning your ability to pull more from anything recently ingested or from fat stores.

For most people this means consuming something like 2000 calories without any replenishment. Which is why marathoners "hit the wall" somewhere around the 20 mile point.

From your description, I think it would be hard to accomplish this. Unless you started your dive day very low on calories or worked very hard reaching the point of bonking is fairly hard to reach.

I've known people that took a long time to recover from a bonk, but nothing like 24 hrs. My own experience is that recovery is very quick with a reduced workload, some food, and water.

Hope this helps.

Carl,
Bonking in the UK means having sex - a Brit reading your post will find it funny .. particularly the last couple of lines. I know it's a serious subject but I'm in a fit of giggles.

reaching the point of bonking is fairly hard to reach.

Tell me about it LOL!!

Sorry, I am british too

...more helpfully, I do run long distances and depleating all your energy stores can make you feel very rough indeed, but I wouldn't expect it to happen without sustained effort over a long period of time... unless you skipped dinner the night before
