Peripheral Chemoreceptor Activity on Exercise-Induced Hyperpnea in Human
It has been reported that hypoxic ventilatory response can be enhanced by an increase in work rate of exercise (Weil et al., 1972; Grover et al., 2002). However, it is still vague about how the muscular exercise produces the enhanced ventilatory responsiveness to hypoxia. Previous studies suggested that afferent nerve activity from carotid body was stimulated by some humoral factors related to muscular exercise, i.e. circulating catecholamine, lactate (Wasserman et al., 1986) and K+ (Band et al., 1985).
