Summary:Departments of 1  Physiology and 2  Electrical and Computer Systems Engineering, Monash University, Melbourne, Victoria 3800, Australia Slow-twitch motor units in the medial gastrocnemius muscle of the anesthetized cat were found to have an average optimum length for active tension that was 0.8 ± 0.5 (SE) mm longer than the whole muscle optimum. For fast-twitch units (time to peak
