Abstract
Twitch characteristics were collected at muscle lengths corresponding to 100, 95 and 90% Lmax. A reduction in muscle length below Lmax significantly reduced the peak developed force. A progressive reduction in both the positive and negative rates of force development was also found as the muscle was shortened from 100 to 95 and 90% Lmax. To determine the influence of muscle length on Ca$\sp{++}$ handling during interval-dependent force recovery, force-interval data was generated in right ventricular papillary muscles from the rat. Fast-flow buffer exchange experiments were then carried out to determine a mechanism for the length-dependent alteration in the beta process. The recirculation fraction of Ca$\sp{++}$ was determined from the beat to beat decay of potentiation at 100, 95 and 90% Lmax. (Abstract shortened by UMI.)
