Effect of fasting on the V ˙ O2-fh relationship in king penguins
dytes patagonicus) may fast for up to 30 days during their breeding period. As such extended fasting may affect the relationship between the rate of O2 consumption (V ˙ O2) and heart rate (fH), five male king penguins were exercised at various speeds on repeated occasions during a fasting period of...
