Fluid and Electrolyte Homeostasis during and Following Exercise: Hormonal and Non-Hormonal Factors.

摘要

Precise control of fluid and electrolyte homeostasis is essential for the survival of man. The performance of exercise results in a significant disturbance of water and electrolyte homeostasis. These alterations during exercise are due to the loss of fluids and electrolytes primarily in sweat and to voluntary dehydration associated with an inappropriate suppression of thirst. During the performance of exercise, as well as during recovery, compensatory measures occur to rectify these changes. A variety of hormones are important in the compensatory responses to correct water and electrolyte disturbances. The goal of this chapter is to describe the changes in water and electrolyte homeostasis resulting from exercise and the responses, regulation, and actions of the hormones important in correcting these imbalances.
