13. K+ shifts of skeletal muscle during stepwise bicycle exercise with and without beta-adrenoceptor blockade.
1. K+ efflux rate and control of K+ reuptake rate in exercising muscle cells was examined in six healthy female volunteers. 2. A K(+)-selective electrode in the femoral vein continuously monitored K+ concentration ([K+]fv) during bicycling. Power was increased stepwise 5-6 times by 30-40 W every fourth minute until exhaustion before and after I.V. administra
