MODULATION OF VENTILATORY CONTROL DURING EXERCISE

The control of ventilatory responses to mild or moderate dynamic exerc ise has been the subject of considerable debate for over a century. Th e prevailing view has been that the ventilatory response to exercise i s stereotypical and rather unmalleable. However, paradigms involving n ovel associations of stimulus inputs have been shown to modulate breat hing in short and longer time scales. The scope of this review include s examples of modified ventilatory responses to exercise which have be en investigated in terms of neural mechanisms. An attempt to synthesis e the available data into a model of neuromodulation is presented. (C) 1997 Elsevier Science B.V.
