Cold immersion test was performed at non-Antarctic and Antarctic conditions by immersing the hand for 2 min in 0- 4?C cold water. The result of this study indicated that continuous cold exposure in Antarctica resulted in vasodilatation which overrides the stronger vasoactive response of acute cold exposure, thereby preventing cold injuries. Besides these circulatory acclimatization to cold there was increase in body mass associated with redistribution of subcutaneous fats. Acclimatization to cold exposure is one of the most important physiological mechanisms for the men in Antarctica (Budd, 1962 Palmai, 1962 and Sjurley, 1970), so as to favour adequate work performance without developing cold injuries. The changes in skin temperature and hand blood flow to cold exposure have been interpreted as indicators of cold acclimatization (Budd, 1964 Budd and Warhaft, 1966). Morphological changes such as body size and insulation by redistribution of subcutaneous tissue have also been found to be associated with cold exposure (LeBank, 1962). The cold induced vasodilatation response has also been reported to be improved in cold acclimatized men (Glaser et al., 1959). However this has not been clearly demonstrated in non-acclimatized men on exposure to Antarctic cold. Therefore the present study was designed to test the acclimatization pattern of skin temperature, finger blood flow and redistribution of fat of Indian men who participated in Antarctic expedition. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. U Sachdeva environment 20.0 140.0 -90.0 30.0 1990-01-01 1991-12-31 Earth Science-Human Dimensions Theme Maitri Antarctic Place Thermal Acclimatization to Cold in Men Exposed to Antarctic Environment during Summer Project eng TableDigital Human Dimensions unknown Human Dimensions distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF720291960&userType=user&freeTextValue=Thermal+Acclimatization+to+Cold+in+Men+Exposed+to+Antarctic+Environment+during+Summer.
