COLDEX-86: Physical Work Capacity during Prolonged Cold Water Immersion at 6.1 msw
Abstract
Response to submaximal leg exercise was quantified in 16 U.S. Navy divers who performed whole body immersions in 5 C water for periods of up to 6 h. Diverse wore passive dry suit thermal protection. Immersions were done during the course of 5-day air saturation dives at a depth of 6.1 msw (20 fsw). Each diver participated in 2 saturation dives. Two immersions were conducted per dive, one beginning at 1000 h, and one beginning at 2200 h; there was a period of 54 h between immersions. During the second saturation dive the presentation of immersion times was reversed. The subjects performed leg exercise on a cycle ergometer for 3 min each at workloads of 50, 70, and 90 watts (W). Heart rate (HR) and O2 consumption (VO2) were measured during the last minute at each workload. The study was divided into 2 series.
