Abstract/OtherAbstract:
Recent work suggests that chronic exercise induces alterations in the contractile properties of cardiac myocytes. These alterations include increased sensitivity to activation by Ca, changes in the force-length relationship, and increased power output. A recently observed shift in expression of myosin light chain 1 subunit isoforms induced by training may provide a molecular mechanism for these contractile alterations.
