[Effect of immobilized adrenaline on the state of the adenylate cyclase system in the cardiac and skeletal muscles of rats in the recuperative period after physical exertion].

It is shown that in the rehabilitation period after a single long physical load the adenylate cyclase activity and cAMP content in the skeletal muscle are low and normalize by the 48th and 36th h, respectively. These indices in the myocardium in the nearest rehabilitation period increase considerably, gradually normalizing by 24th and 48th h, respectively. Immobilized epinephrine accelerates normalization of the adenylate cyclase activity and cAMP content in the skeletal muscle and in myocardium in the rehabilitation period after physical load, the phosphodiesterase activity being unchanged.
