Summary
The origins of the rat fast plantaris and slow soleus muscles were surgically reversed and their fibre types and contractile properties examinedin vitro up to 12 weeks post surgery. Muscles in which the origins had been severed and then immediately sutured back in place served as one control group. Unoperated animals served as a second control group. As compared to these groups, no significant differences in the histochemical or mechanical properties of the repositioned muscles were detected. Under the conditions of the experiments, no evidence was obtained to indicate that the intrinsic properties of a muscle could be altered by changing its site of origin and thus its functional environment.
