Ion gradients and contractility in skeletal muscle: the role of active Na+, K+ transport.

Abstract

Intensive contractile activity is associated with a significant net loss of K+ and a comparable gain of Na+ in the working muscle fibres. This leads to an increase in the interstitial and T-tubular K+ concentration and to a decrease in the T-tubular Na+ concentration. It is well established that the exposure of muscles to high extracellular K+ or low… (More)
