Peripheral and whole-body cold acclimatization in Antarctic scuba divers

The purpose of this investigation was to determine whether the cold exposure associated with polar scuba diving operations could result in measurable cold acclimatization in humans. Antarctic-cold-exposed (ACE) subjects (n = 4; male) lived in semi-permanent structures in an isolated field camp (77$\sp\circ$S 163$\sp\circ$E) during the austral spring, conducting 4.9 $\pm$ 0.6 (4.3-5.9) dives per week for biological research (water $-1.9\sp\circ$C; air $-$36.7 to $-5.8\sp\circ$C). Matched bi-weekly-tested (BWT) subjects remained in the U.S. throughout the study period (autumn). Physiological responses to standardized peripheral (30 min digit immersion, 4$\sp\circ$C water bath) and whole-body (90 min air exposure, 5$\sp\circ$C, supine, rest) cold tests were evaluated at two week intervals for six weeks
