Superfast contractions without superfast energetics: ATP usage by SR-Ca(2+) pumps and crossbridges in toadfish swimbladder muscle

1. The rate at which an isometrically contracting muscle uses energy is thought to be proportional to its twitch speed. In both slow and fast muscles, however, a constant proportion (25-40 %) of the total energy has been found to be used by SR-Ca(2+) pumps and the remainder by crossbridges. We exami...
