Abstract:

Exercise is intrinsic to military and commercial diving, and exercise may either increase or decrease the risk of decompression sickness DCS after diving. Vann and Thalmann 1 explained the relation between exercise, diving, and the risk of DCS using the parameters of exercise intensity, exercise duration and the phase of diving during which exercise is performed. Before diving, intense, vigorous or ballistic exercise which induces muscular soreness may also create microscopic intramuscular gas nuclei which increase the risk of DCS. During diving, the increased metabolic rate of exercise can enhance the rate of inert gas absorption, rapidly causing tissue supersaturation and subsequently increasing the risk of DCS 2-4.
