Abstract

In this study of contractile tissues, temporal changes in unloaded velocity of shortening and myosin ATP utilization were measured and are shown to be closely related in time respectively to changes of tissue hysteresivity and the product of tissue hysteresivity and elastance. Overall, results suggest that the rate of actomyosin detachment, in contrast to the classical viscous stress, seems to be of major importance in the frictional stress developed within contractile tissues.
