Exercise after diving

Postby Andy » Tue Apr 07, 2009 4:28 pm

Is excersising after diving safe?

I've read some stuff that "activity" (certainly during decompression) can actually reduce the risk of DCS - presumably increased blood flow improves passage of nitrogen through the system. It's certainly not busting out underwater star jumps, but gentle movement. I'll see if I can dig the article out.

As for post-dive, I would hazard a completly-ill-informed-non-medical opinion that any exercise has the potential to cause DCS. How vigorous or how soon after diving that it is "safe" is very much going to be down to individual physiology.

The Rubicon Foundation will no doubt have some articles on this in their repository:

Yup, like what Andy said... How long is a piece of string.

The way I approach it is... There are somethings that increase your risk of DCI and somethings that decrease your risk of DCI.

If you are close to reaching a limit such as after a deep dive and/or deco dives, then the more things you can do that reduce risk, and the more things you can avoid that increase risk... then the better the chance of you not getting bent. Not exercising after a dive is just one of those things.

So to answer a piece of sting question with an equally long piece of sting :-)

The closer to any limit I am, the longer I won't excercise after a dive.

I did a really long deep dive a few months ago..... I've not been to the gym since.... just in case you understand... :-)

I'd suggest some moderate exercise around about now. 568g of cool liquid in a glass vessel, bend at the elbow towards the mouth.

To restrict the chance of DCS, you should use a decreasing amount of weight - so I'd suggest sipping some of the beer on each repetition to decrease the resistance.

I got so carried away not exerting myself that I forgot your second question.

In a diving context the type of things you may plan to avoid would be:
Hard surface swims, climing out of the water with loads of cylinders/weight hanging off you. Walking up a hill/cliff. (Rocky bay is out for deco dives!)

When I've finished a dive at Taupo for example, I would ideally swim underwater nice and relaxed all the way to the shore, then sit there and take off my sling tanks nice and slow and relaxed then walk out of the water and take my gear off. Then no need to rush and get packed up or run arround panicing. Just nice and slow and relaxed, and that's just to 45m.

The guys going for the deeper longer dives will do this even more. Some of them will sit on the boat / surface and just breath pure O2 for a while to also help reduce their risk of DCS.
