Fig. 2From: Effects of acute hypobaric hypoxia on thermoregulatory and circulatory responses during cold air exposureRectal temperature (a), mean skin temperature (b), and forehead temperature (c) by air temperature changes in NC and HC. Data were expressed as mean ± SD. *Significant difference compared between conditions. NC normobaric normoxia with cold; HC hypobaric hypoxia with cold; phase 1 (P1) Tair was 28 °C and PB was 760 mmHg in both conditions. Phase 2 (P2) Tair was 28 °C in both conditions, and while PB was maintained at 760 mmHg in the NC condition, PB was decreased from 760 to 493 mmHg in the HC condition. Finally during phase 3 (P3), Tair was decreased from 28 to 19 °C in both conditions and PB was 760 mmHg in NC and 493 mmHg in HCBack to article page
