Fatigue of isolated mouse muscle due to isometric tetani and tetani with high power output.
The fatiguing effect of a series of isometric tetani and of tetani with shortening and maximum power output were compared using soleus and extensor digitorum longus muscle of mouse. Mean force in test isometric tetani after the series was reduced by up to 35% compared with pre-series controls. Tetani with shortening were always more fatiguing than isometric tetani.
