Catabolism definition is - degradative metabolism involving the release of energy and resulting in the breakdown of complex materials (such as proteins or lipids) within the organism. Muscle Metabolism. Catecholamines activate muscle glycogenolysis and lipolysis. These are associated with loss of muscle function and accelerate rapidly from the age of 60 … Before being available for intracellular metabolism, glycogen is obtained when glucose is converted to glycogen. Metabolism is the rate in which your body processes what you have eaten. The main sources of fuel for muscles are carbohydrates and lipids. Carbohydrates can be metabolized either in the presence of oxygen (aerobically) or in its absence (anaerobically), but lipids can be metabolized only aerobically. muscle metabolism synonyms, muscle metabolism pronunciation, muscle metabolism translation, English dictionary definition of muscle metabolism. Muscle Metabolism: Aerobic vs. Anaerobic By Thomas Griner. Trained athletes have an increased ability to metabolize fatty acids as compared with sedentary people; this permits athletes to exercise longer and at higher work rates than untrained people. The metabolic basis for a change in muscle mass is an increase in net muscle protein balance (termed NBAL). metabolism [mĕ-tab´o-lizm] 1. biotransformation. However, as intense exercise continues, glycogen stores are exhausted, and free fatty acids become the principal source of energy. What is "Hyper" in the ALS Hypermetabolism?
