System 2
The second system that is still high intensity is the lactic acid system, which is also anaerobic. Lactic acid is when ATP stores and PC have run out of the body, which has another way to provide energy quickly. This is a sort system runs for one to three minutes. Lactic acid is a waste product.
The sporting activities, which would use the lactic acid system, are eight hundred meter run, tennis rally and gymnastics routines. A four hundred meter track run relies on the breakdown of glucose, which is stored in our muscles as glycogen is stores of carbohydrates, which are in our muscles. This system works by breaking down glycogen, this is the energy source.
Four hundred meter sprint energy is still needed quickly so there is no time for oxygen to get to the moving muscles this is glucose is broken down without oxygen. Know as the anaerobic glycolysis. As glucose is broken down in the muscles, which provides the energy to recreate the ATP, by a product called lactic acid produced. The burning sensation is because the lactic acid is building up and wont want you to carry on since there is no oxygen, which prevents us completing and limit the performance. If too much lactic acid circulate you wouldn’t be able to contract our muscles. Before using these muscles again they will need to replace ATP, removal of lactic acid, replenishment of myoglobin with oxygen and replacing glycogen. To remove lactic acid we would have to do a cool down which requires a slow jog and stretches. This will help circulate oxygen around our body to get rid of lactic acid.
To prevent lactic acid athletes should stretch before and after completing exercise. Muscular contraction is needed to rapidly so that the body doesn’t have enough time to deliver oxygen to the working muscles. Oxygen debt will occur when the metabolic process is used and not requiring oxygen so that athlete’s respiration rate will be very high.
The formula for lactic acid is Glucose ---> Pyruvic acid = No oxygen ---> Energy = Lactic acid
