Susceptibility to hypoxia and breathing control changes after short-term cold exposures

Figures & data

Table I Design of experiment with cold exposure

Days	Conditions of measurement	Measured parameters
0	Thermoneutral (26°C)	Anthropometric data, gas exchange, hypoxic ventilatory response, hypercapnic ventilatory response
1	Cold exposure (2 h, 13°C)	The core temperature (Tre), the temperature of the skin (Tsk) and the body (Tb), contractile activity of skeletal muscle, the heat debt
1–9	Cold exposure (2 h, 13°C)
10	Cold exposure (2 h, 13°C)	The core temperature (Tre), the temperature of the skin (Tsk) and the body (Tb), contractile activity of skeletal muscle, the heat debt
11	Thermoneutral (26°C)	Anthropometric data, gas exchange, hypoxic ventilatory response, hypercapnic ventilatory response
