Importance of Arterial Chemoreceptors for Cardiorespiratory Responses to Static Exercise in Man
Static isometric exercise leads to a rapid heart rate acceleration and pulmonary hyperventilation (Miyamoto et al., 1987). The heart rate acceleration is known as a muscle-heart reflex, originates in muscle receptors affected by noxious chemical and mechanical stimulation, and is mediated by group III and IV afferents (Gelsema et al., 1983). The mechanism of the hyperpnea is uncertain, as is also the role of chemical drive in both cardiac and respiratory events of static exercise.
