Abstract

EXCITATION-CONTRACTION (E-C) coupling in skeletal muscle is a series of events leading from membrane depolarization to the production of tension1. One of the more important intermediary processes is a transient increase in the sarcoplasmic calcium concentration (calcium transient2) during the rising phase of tension. We have simultaneously recorded changes in membrane potential, calcium transient and tension during a single contraction of an isolated muscle fibre.
