Fig. 6. Total isometric force (active + passive force) at the final length (f), and
total isometric force following muscle stretching of 3 mm, 6 mm and 9 mm (3, 6
and 9, respectively) to the final length (f) for representative tests at a
stretching speed of 3 mm s-1. Note that the steady-state force
enhancement following stretching increases with increasing magnitudes of
stretching on the descending limb of the force—length relationship of
cat soleus muscle. The corresponding mean results of force enhancement across
all muscles, speeds of stretching, and activation frequencies are summarized
in Table 2.
