Such an approach was used in a group of volunteers before and after a ski journey (3 weeks at −20 to −30°C) across Greenland. Eight subjects were submitted to cold tests (T db = 1°C, r.h. = 40%, wind speed = 0.8 m · s−1) for 2 hours. Thermoregulatory changes were also monitored in a neutral environment (T db = 30°C). In the neutral environment, the arctic journey increased metabolic rate (11.2%; P<0.05) and mean skin temperature [ $$\bar T_{sk} $$ : 33.5 (SEM 0.2)°C vs 32.9 (SEM 0.2)° C, P<0.05]. During the cold test, the arctic journey was associated with a lower final rectal temperature [36.8 (SEM 0.2)°C vs 37.3 (SEM 0.2)° C,P<0.01], a lower final $$\bar T_{sk} $$ [20.7 (SEM 0.4)° C vs 21.2 (SEM 0.3)° C,P<0.011 with no change in metabolic heat production. These observations are indicative of an hypothermic insulative isometabolic general cold adaptation, which was associated with a local cold adaptation of the extremities, as shown by warmer foot temperatures [12.3 (SEM 0.9)°C vs 9.8 (SEM 0.9)°C,P<0.001].
