Diving and working out

[SpankyGirl]

( I posted this under a different forum but I feel it might to better here)

I should also note , which I did not on the other post I have high blood pressure and working out keeps it good.

Well here it is:

I have sent a letter off to Dan and posted it on my clubs website, then Dr. Steve in the club posted a little note with it. I was wonder if anyone has any other knowledge about this to pass on. I really do not want to go away and not be able to work out at all. I am happy to switch my pilates to the morning and not jog at all, but I am so longing to jog at least once along the beach.
Here is the post and my email I rec, from DAN .




It kind of makes me wonder if this person knows what Pilates is. As
DocVikingo on scubaboard has said on numerous occasions it is the
elevated heart rate that makes exercising after diving dangerous. As
a long time Pilates advocate I cannot imagine it being dangerous to
do after diving as the heart rate is only slightly elevated, in fact
the gentle stretching should aid in the deco process. But I could be
wrong...try posting this on scubaboard and see the response.

Mmm, I don't think that's what DocVikingo meant, and Marty's (of DAN) response is entirely consistent with someone who knows what Pilates is.

Actually, elevated cardiovascular activity accelerates off-gassing. However, this increased heart rate is usually the result of movements that in themselves can cause dissolved gas to come out of solution (cavitation) and trigger DCS. Pilates definitely involves movements that might cause cavitation without elevating heart rate. So, the prudent thing is to avoid exercise for several hours after diving to recreational "no-deco" limits.

Running before your dive is likely mentioned specifically by Marty because of evidence that cardiovascular activity performed within 24 hours leading up to a dive might offer a protective effect. It might also do nothing at all, but it seems pretty clear that cardiovascular exercise before diving is not harmful, as long as you are well hydrated and rested before your dive.

Why not run before your diving some days and do Pilates before your diving other days?

Thank you.. I figured I can jog in the morning, nothing prettier then the beach at sunrise. But worst case is just do my pilates in the morning. I am addticted to them.

I will just switch my work out routine around while I am in Cozumel. I normally jog at night or use the tread mill, pilates in the moring..they really get me ready for my work day.

I just wish that people who don't know , don't scare people into thinking you can never work out on a dive trip. I understand all the concerns , but I believe with moderation and a good understand you can. My own doctor advised me tp ask DAN . She knows I am an diver and has actually been reading up on it to help me out better, so I am sure durning my check up next week she will tell me the same thing every one else has. However I wanted to be safe and ask and what better place then here.

Well, many of the studies suggesting pre-dive cardiovascular exercise is safe were only published in the past few years, and exertion right after diving is a known bender. NASA did some studies on exercising before decompression to altitude that showed an increased risk of DCS, but these studies were more akin to a diver exercising at depth, which we know is bad from similar studies. For a while, the NASA studies were all we had to go on, so DAN and others made recommendations to limit pre-dive exercise as well as post-dive exercise. In fact, DAN's website still mentions the NASA studies in its posted recommendations, but does not mention the more recent studies done specifically on diving.

In any case, exercise on dive day is still an area of active research. What we consider safe to do before and after diving is still being refined.

I see just a little bit here of fishing around until getting the desired answer. That's something to be careful of.

On whose part, mine or SpankyGirl's? Do you disagree with the answer I provided?

I take my health very seriously and, yes I love diving. However I feel that with moderation I should be able to do some lighter work out or Jog at least 3 of the days that I am there. I like to keep my routine. I also feel posting on here and being able to hear others opinions is a great assets. So if I am fishing, then I am fishing. I have spoke to DAN. Plus a few other instructors I trust. I value what others say and I appreciate the fact that people do answer me.

No I don't disagree with your answer. I was not refering to your post, not even sure why you would think that.

I guess that because you provided no context with your post, I wasn't really sure who you were warning or what you were warning about. That's all. <g>
