Blood And Excerise :: essays research papers

Blood and ExceriseType II muscle fibers oxidize lactate at a very fast rates. When musclecontraction produces a significant amount of lactate, it is so released intothe central circulation of the blood, and within seconds it is made available tothat muscle for thrust. Therefore, 75% of the lactate produced from high loudness exercise is made available for energy production in type II musclefibers. The remaining 25% of lactic acid is used for energy in the heart, themake up of liver animal starch, and the supply of energy to inactive muscles. A goodexample of this would be a runner who is exceeding his or her planned race pacein a 10k. The excess lactic acid accumulated in the contracting muscle frominsufficient oxygen is then made available to inactive muscles (e.g., the arms)from the central circulation of blood. The remaining lactic acid that is notdirectly oxidized for fuels is sent to the liver, where it is stored as glycogen.In the process of exercise, glycogen is released into the blood stream to formglucose.Lactate is GoodAs coach and athlete you must learn how to teach the body to plough lactic acid.It is imperative, if you ask successes in todays highly competitive field ofathletics to train your muscles, body and mind to accomplish gains inperformance even in the presence of lactic acid. Coaches and athletes shoulddesign training programs with this being a primary focus. This is done by twobasic components of training. Long Slow Distance (LSD) training beyond the chemical formula racing distance, will develop tissue enzyme adaptations that will relyupon the use of free fatty acids for energy production, which will result inless lactic acid being produced. LSD training will also ontogenesis the rate oflactic acid removal from the blood and muscles. During continuos steady stateexercise, you increase capillary density and mitochondria function in skeletalmuscle, These two peripheral adaptations brought on by LSD training will enableyour body to handle lactic acid much more efficiency. High intensity trainingwill develop the cardiovascular system to increase the rate of oxygen taketo the contracting muscles so there is less reliance on carbohydrate breakdownto lactic acid. High intensity training much(prenominal) as intervals., and versatile paceworkouts, will increase your functional capacity (Max VO2). This means that inactual competition you will produce less lactic acid, because your muscles arerelying broadly on the use of free fatty acids for fuel. The lactic acid that isproduce will be removed by the tissues that can use it as fuel, such as the
