Blood lactic acid on the aerobic anaerobic exercise of.doc

Blood lactic acid on the aerobic anaerobic exercise of Abstract Because of the blood lactic acid in the scientific training has played an important role, as well as a growing number of coaches, researchers began to be applied in the training process, so the blood lactic acid on the aerobic, anaerobic exercise significant influence, this paper to investigate the blood lactic acid on the aerobic, anaerobic exercise effect. Keywords: aerobic exercise anaerobic exercise blood lactate I. Introduction Blood lactic acid is a study of exercise training in the early indicators, but also a modern scientific sports training, one of the most widely used indicator. Blood lactic acid as the development of training methods have to master the appropriate exercise intensity to assess the athletes, aerobic metabolism and anaerobic metabolism in the body of the main indicators [1]. 2, blood lactate generation Blood lactic acid is lactic acid energy system can be time for the end product of metabolism, when the body is exercise, the body’s sugar reserves decomposed functions, 1mol complete oxidation of the sugar produced 38-39molATP, way to enter the citric acid cycle, the product is water and carbon dioxide . When insufficient oxygen and glucose metabolism into another way - anaerobic glycolysis, in the process of glycolysis the continuous generation of pyruvate, the major metabolic pathway of pyruvate entering the citric acid cycle in the mitochondrial oxidation. In addition, through the lactate dehydrogenase catalyzed into lactic acid during exercise pyruvate generated inside the muscle cell increase, according to mass action law in which there must be a part of pyruvate generates lactic acid. Moreover, when a larger intensity exercise, accelerated glycolysis, pyruvate formation rate greatly increased, if the rate of pyruvate formation over mitochondrial metabolism, a large number of pyruvate bound to lactate dehydrogenase from the catalytic converter into lactic acid, Then in
