Dr Deco:
This was an interesting comment. My partner and I can say from about five 400+ foot altitude dives (mixes appx. 10/70) with a conservative decompression schedule with deep stops that if we did not relax post dive our biceps would ache. We even started having a designated driver for us due to it not being comfortable to maintain our hands on the steering wheel. I didn't even like to hold a cell phone. Now when we relaxed, we didnt notice any diving effects. But one dive that I found memorable is that I was having a little difficulty getting out of my rig in the water (we never do any post dive exercise ... including getting on the boat with our rig on), so a safety diver helped me. He loosened my shoulder strap and bent my arm at the elbow so I could pull out. It was still snug so my arm stayed in that position for a little while until the shoulder harness was loosened even further. While my arm was relaxed, but bent, my bicep started aching pretty good where I was silently praying for him to hurry up and finish loosening the strap. Once it was out it felt fine again. I know there can be many explanations for this, but it is interesting we consistently noticed this type of ache on a high helium mix. Just wanted to share this due to the comments on helium and muscles.
