Title Aerobic exercise 2 hours before a dive to 30msw decreases bubble formation after decompression
Bibliographic information July 2005, Vol.76, No.7, Section I, p.666-669. Illus. 27 ref.
Abstract This study investigated the effect of aerobic exercise two hours before a dive. Sixteen trained military divers were compressed to 30msw for 30min breathing air in a dry hyperbaric chamber at rest and then decompressed. Each diver performed two dives three days apart, one with and one without exercise that consisted of running 45min at 60-80% of maximum heart rate. Venous gas emboli were graded at 30min and 60min after surfacing. Mean bubble grades at 60min were 1.25 for control dives and 0.44 for dives preceded by aerobic exercise. This difference is highly significant. Running 2h before a dive decreases bubble formation after diving. The mechanism underlying the protective effect of aerobic exercise remains unclear.
