I see by Fitness For Living, January-February issue, that my carbohydrate meal every third day when on a total protein diet is now being used by athletes to load the liver with glycogen for maximum performance.
Procedure is as follows: six days prior to competition, the athlete trains very hard on protein and fat and depletes his reserves of glycogen. Three days before competition, he adds considerable carbohydrates to his diet and loads up the glycogen in the liver and by so doing, improves his endurance up to 150 per cent.
During mild exercise, muscles get all of their energy from fats. During strenuous exercise, the muscles must rely increasingly on carbohydrates in the form of glycogen.
Also, numerous studies show that muscles do not grow larger or stonger on abnormally high protein intake.
