Potassium loss from skeletal muscle during exercise in man: a radioisotope study [PDF]

Experimental Physiology, 1993
Muscle potassium (K+) content decreases during exercise. Previous studies, in humans, have used measurements of arteriovenous plasma potassium concentration differences (AV delta[K+]) and/or muscle biopsy to measure the loss of muscle K+ during exercise.
