Abstract
Diving mammals and birds exhibit drastic cardiovascular adjustments to restrict oxygen consumption during diving. The response involves selective peripheral vasoconstriction and heart rate reduction (reviews 1–3). Similar but less pronounced adjustments occur at apneic face immersion in man and dog, but data from voluntary diving in other terrestrial species are scarce (review 4). In some species, including man, the response is temperature dependent, indicating the involvement of thermoreceptors in its elicitation (5–7). The aim of the present study was to quantify some circulatory adjustments occuring at voluntary apneic snout immersion in trained pigs, and to reveal if temperature receptors contribute to the triggering of this response in the pig.
