title: [Protein nutrition and physical activity].
abstract: The relationship between physical exercise and diet in order to optimize performance is getting growing interest. This review examines protein needs and protein intakes as well as the role of protein in the body and the metabolic changes occurring at the synthesis and catabolic levels during exercise. Protein synthesis in muscle or liver, amino acids oxidation, glucose production via gluconeogenesis from amino acids, etc., are modified, and consequently plasma and urinary nitrogen metabolites are affected. A brief comment on the advantages, disadvantages and forms of different protein supplements for sportsmen is given.
