Resumo

To investigate skeletal muscle capacity for performing cardiac type work gross contractile properties of electrically conditioned and normal muscle (Lastiseimus dorsi/seven dogs) were compared. Optimum pacing parameters were found to be the same for both type of muscle (50 Hz, 150 ms, supramaximal stimulus amplitude). The force of contraction measured during an isometric tension state was decreased for conditioned muscle as compared to normal muscle (2.8 ± 0.3 vs 3.8 ± 004 Kgf/100 g in control).
