Repetitive isometric tetanic contractions (1/s) of the canine gastrocnemius-plantaris muscle either were studied at optimal length (Lo), or short length (Ls0.9.Lo), to determine the effects of initial length on mechanical and metabolic performance, in situ. Respective averages of mechanical and metabolic variables were (Lo vs. Ls, all p
