Influence of Exercise on Protein and Amino Acid Metabolism

Abstract The sections in this article are: General Aspects of Amino Acid and Protein Metabolism in Muscle Amino Acid Transport and the Free Amino Acid Pool Outline of the Metabolism of Amino Acids in Muscle in Relation to Exercise Interrelationship ofBCAA, Alanine, and Glutamine Metabolism The Purine Nucleotide Cycle in Muscle Amino Acid Catabolism and Gluconeogenesis from Amino Acids in Liver and Kidney Training Effects on the Capacities of Muscle Enzymes of Amino Acid Metabolism The Effects of Contractile Activity on Ammonia Production and its Relation to the Free Amino Acid Pool Alterations of Muscle and Blood Amino Acid Concentrations during Exercise Production and Consumption of Amino Acids by Muscle during Exercise Effects of Training on Amino Acid Metabolism during Exercise Interrelationships between Working Muscle and the Viscera during Exercise Protein Turnover During Exercise Effects of Acute Contractile Activity on Protein Turnover Postexercise Alterations in Muscle Protein Synthesis Effects of Habitual Exercise on Whole‐Body Protein Turnover Effects of Immobilization and Disuse Collagen Turnover in Muscle Physical Activity and Protein Requirements Outstanding Questions
