Changes of Organic Metabolism in Long-distance Running in Fish Meat Protein Nutrition and Sports Biochemical Analysis
Marine fish are rich in protein nutrition, rich in amino acids and polyunsaturated fatty acids in fish, and have a comprehensive composition of trace elements. The proteins of the back muscles, abdominal muscles and fish heads conform to the ideal protein model recommended by FAO / WHO. The amino acid composition of the abdominal muscle proteins is balanced and has the highest nutritional value. This article analyzes the changes of organic metabolism during long-distance running in fish protein nutrition and sports biochemical analysis. Through an in-depth study of sports biochemical theory, the energy supply of the three major energy supply systems in the human body and the laws of matter and energy metabolism during exercise are analyzed. From the perspective of sports biochemistry, the energy supply and metabolic rules of middle-and-long distance running are explained, the purpose is to provide theoretical basis and guidance for improving the energy supply ability and scientific training of middle and long distance runners.
