Muscle metabolism and electrolyte balance during heat acclimation.

This paper presents the findings from a series of studies that examine the influence of repeated days of exercise in the heat and dietary K+ and Na+ on heat acclimation. Data are presented to examine the effects of heavy sweating on potential risk of K+ depletion. Studies of leg blood flow, substrate exchange (a-v differences) and muscle glycogen use during exercise have been used to describe the influence of a heat acclimation regimen (8-days exercise in the heat) on peripheral metabolism.
