The Biochemistry of Muscle Training

Abstract

Training was produced in muscles by electrically stimulating the muscles in 1 extremity 10-15 mins. twice per day for 15 days. The work capacity of these muscles as well as the glycogen and creatine content increased. There were increases in the respiratory processes and in the aerobic and anaerobic glycolysis. The conditions for synthetic processes were improved. Alterations in the metabolic processes following fatiguing work were not simply localized in muscle. Lack of vit. C in guinea pigs caused a more rapid onset of fatigue, and similar results occurred in pigeons fed on a thiamin-free diet. Work on an acid diet interrupted to a lesser degree the oxidation of phenol than synthesis of its detoxication product, but it interrupted these processes to a greater degree when on an alkaline diet.
