Eight members of the research diving community in Tallahassee, Florida were volunteers for this project to determine if there was an acclimation effect due to repeated cold exposures in water 18(DEGREES)C at two atmosphere of pressure absolute, three days per week for two weeks breathing air. / The divers performed three 30 minute dives per week for two weeks wearing bathing suits and diving the Kirby Morgan Band Mask (KMB). Each diver completed series of pre- and post-acclimation tests in a cold water bath at 25(DEGREES)C, which included the monitoring of mean skin and body temperatures, Vo(,2) and thermoregulator Vo(,2), and maximum tissue insulation. Each diver also had their perceived cold, post-dive finger temperatures, and time to shivering onset recorded during each of the six dives. / A significant decrease was seen in MST and MBT at the shivering threshold between the pre- and post-acclimation cold water bath exposure test and cold air exposure test. No difference was seen in the thermoregulatory Vo(,2) at the shivering threshold between the pre- and post-acclimation cold water exposure test. There was also a significant increase in time to the onset of shivering during the cold water exposure test, cold air exposure test (at 5(DEGREES)C), and during the six cold water dives. There was a decrease in the perceived cold as reported by the subjects over the six cold water dives. There, however, was no difference between the pre- and post-acclimation tissue insulation. / There was an acclimation effect from the two week diving exposure in cold water evidenced by an decrease in shivering threshold, a reduction in post-dive finger temperature, and an enhanced feeling of well being by the divers over the two week period of dives. / Source: Dissertation Abstracts International, Volume: 46-04, Section: B, page: 1078. / Thesis (Ph.D.)--The Florida State University, 1985.
