Summary and Conclusions
-
(1)
Substances that depress metabolism suppress relaxation of unloaded muscle and increase that of loaded muscle.
-
(2)
It is therefore concluded that relaxation in unstriated muscle is of two kinds, one active and the other passive.
-
(3)
Substances that increase metabolism may diminish the mechanical response, by simultaneously increasing active relaxation, while the muscle is contracting.
