Abstract
CHANGES have been reported in muscle electrolytes with age1, and several laboratories throughout the world have reported similar changes2–5. From birth to maturity the sodium and chloride content in a unit muscle mass decreases while the potassium increases. These changes are often interpreted as a function of increasing muscle cell size and a decreasing extracellular space in the muscle.
