Rate of heat output from resting human skeletal muscle

Forearm resting VO2 at 35°C	2.2	ml (liter muscle)−1 min−1	Zurlo et al. (1990)
Rate of muscle heat production at 35°C	46	J (liter muscle)−1 min−1	Assuming 20.9 kJ (liter O2)−1
Express in W (kg muscle)−1	0.73	W (kg muscle)−1	Muscle density, 1.06 kg liter−1
Express in W (kg myoplasmic water)−1	1.2	W (kg myoplasmic H2O)−1	Whole muscle volume = 1.45 × myoplasmic H2O volume (Table 3)
Rate of muscle heat production at 25°C	0.60	W (kg myoplasmic H2O)−1	Q10 = 2 (Barclay et al., 2009)
