Skeletal Muscle Kir6.2 Protein Expression Correlates To Ion Transport Capacity And Exercise Performance In Athletes

Skeletal muscle ion regulation may affect exercise tolerance during intense muscle work. However, the inter-play between different sarcelemmal ion transport proteins is not well described in trained skeletal muscle. PURPOSE: To examine associations between protein expression of Kir6.2, a key subunit of the ATP-sensitive K+ channel (KATP channel), and exercise performance, as well as different ion regulators and fiber type profile in trained...
