Divers will be asked to form two groups, one which will be given NO and asked to exercise and a control group which will take part in the exercise programme but with a placebo. Both groups will then dive in the 30 - 50 metre range without completing in water decompression and will be monitored for bubbling on their return to the surface.

Does this study have ethical approval?
Surely being in the placebo group is asking for trouble. Even if the pill works by preventing bubbles, the placebo is going to do nowt, therefore a 30-50m dive without any deco stops is a bit dangerous.
Ignore - date noted!!
