Control of Breathing during Exercise.

Control of breathing during exercise.

During exercise by healthy mammals, alveolar ventilation and alveolar-capillary diffusion increase in proportion to the increase in metabolic rate to prevent PaCO2 from increasing and PaO2 from decreasing. There is no known mechanism capable of directly sensing the rate of gas exchange in the muscles or the lungs; thus, for over a century there has been intense interest in elucidating how respi...

Determinants and control of breathing during muscular exercise.

Introduction Exercise hyperpnoea is considered to be one of the major remaining challenges to understanding the control of human systemic function. The topic is currently in an exciting phase, both with respect to novel perspectives on its control and the application of novel techniques to investigate previously proposed mechanisms. However, despite this, the integrative aspects of the control ...

Arterial blood acidity and control of breathing during exercise.

The recent paper by Wasserman et al. (2011) on “arterial H+ reglation during exercise in humans” is to be regarded as part of the ong tradition in respiratory physiology to decipher why and how entilation rises by tens of liters per minute during exercise with o increase in PaCO2/[H] +a (Comroe and Schmidt, 1943; Kao, 1956; ejours, 1959; Whipp and Ward, 1980, 1991; Whipp et al., 1983; asserman ...

Control of breathing during sleep.

Mental processes and breathing during exercise

Breathing during exercise is an important physiological function for maintaining homeostasis of hydrogen ion concentration ([H+]) in the internal environment. In general, ventilatory response during exercise is considered to be automatically (unconsciously) controlled depending on exercise intensity and the corresponding perturbation of neurohumoral factors. However, in awake humans, the act of...
