chemical substance found in foods that is used in the human body. The nutrients needed in the human diet are amino acids, fatty acids, minerals, vitamins and water. Metabolic fuel is often supplied from carbohydrates and fats, which are almost, always present in human diets but specific carbohydrates are not essential. * Metabolic fuel can also be supplied from proteins. Chemical energy is all the fuels are transferred into a required movement/action (contracting muscle) by respiration. *

phosphate and anaerobic glycolysis. The runners can perform almost without breathing, using energy stored as ATP, creatine phosphate and glycogen which is anaerobic metabolism in the active muscles. In contrast to long distance runners, sprinters are often large. Muscular people. Sprinters have dominance of so called fast twist or anaerobic muscle fibers. Those remarkably high speeds can only be maintained while stored high energy phosphate in the form of phosphocreatine is present, however phosphocreatine
