Total energy provided by aerobic energy system is 38 ATP.
Comparison of the different muscle fiber types: It is obvious from the table above that Type IIx is the most powerful fiber but it doesn't last long (because it mostly relies on anaerobic energy system).
There are three major energy systems in the human body that yield ATP (adenosine triphosphate: the body’s energy source). They are the phosphagen system, glycolytic system, and oxidative phosphorylation. The systems will be explained later on in this section. They are important in sport because each system is used differently at different intensities. This is why sport specific training is so important in athletic performance. You must first recognize the difference between anaerobic and aerobic metabolism.

Glycolysis is the breaking down of glycogen (stored glucose or carbohydrates in the muscle). Glycolysis can rapidly produce ATP with out oxygen. However, it cannot produce ATP as fast as the phosphagen system. Glycolysis involves the breakdown of glucose or glycogen to form two molecules of lactic acid or pyruvic acid (this outcome depends on other metabolic factors). In simple terms glycolysis uses energy from glucose to form ATP. This is the same principle as the phosphagen system but it goes through a much more complex process to form the ATP.
The maintenance of a limited intramuscular supply of ATP and the production of AMP, Pi and ADP mediated by phosphocreatine and adenylate kinase as mentioned above, rapidly stimulates the breakdown of macronutrients to resynthesize ATP at a rate equivalent to ATP’s rate of use and intensity of physical activity. While ATP hydrolysis occurs anaerobically enabling rapid energy transfer during strenuous short-lived physical activity; the resynthesis of ATP can be aerobic or anaerobic in the case of glucose metabolism or exclusively aerobic for lipid and protein metabolism.

metabolite of the lactic acid system resulting from the incomplete. at the start of exercise the body cannot deliver oxygen to the muscles fast enough to initiate the complex chemical reactions which occur during aerobic metabolism. in a 1Â km run, this system is already providing approximately half the energy; in a marathon run it provides 98% or more. stage of the aerobic system occurs on the cristae (infoldings on the membrane of the mitochondria). an example of an activity of the intensity and duration that this system works under would be a 400 m sprint.
- working at 95% effort these energy pathways are time limited and the general consensus on these times are as follows:Atp + cp + muscle glycogen. primary function of the digestive system is to break down food both mechanically and by the use of enzymes, so that it can be used by the body for energy and cell growth and repair. another limitation of the lactic acid system that relates to its anaerobic quality is that only a few moles of atp can be resynthesized from the breakdown of sugar as compared to the yield possible when oxygen is present. aerobic refers to the presence of oxygen, whereas anaerobic means with series of chemical reactions that does not require the presence of oxygen. the energy for atp resynthesis comes from three different series of chemical reactions that take place within the body.

Therefore, when you exercise you speed up the energy systems and thus more CO2 is produced. We could dive much further into aerobic ATP production but we won’t. People have written entire books and have dedicated their life’s work to understanding it. We are just scratching the surface.

Let’s go into the mitochondria at this point and see what is going on. Aerobic ATP production (Oxidative Phosphoralation) goes on in the mitochondria and involves two metabolic pathways known as the Krebs Cycle and the Electron Transport Chain (ETC). The primary role of the Krebs cycle is to complete the oxidation (hydrogen removal) of carbohydrates, fats, and proteins. Hydrogen removal is important because hydrogen’s contain the potential energy in food molecules.

would then stop and rest as your atp-pc system is depleted.. the carbohydrate store will last approximately 90 minutes and the free. it is stored in muscle cells phosphocreatine is readily available to produce atp quickly. conversion to lactate occurs when the demand for oxygen is greater than the supply (i. atp stores last only a few seconds after which the breakdown of pc provides energy for another 5-8 seconds of activity. are the bodies preferred source of food energy for the synthesis of atp, with one gram of cho providing four calories of energy. acids either circulate in the blood or are stored as triglycerides in adipose tissue and muscle. exercise begins energy will come from the anaerobic energy systems, the initial 10 seconds or so are almost exclusively through the atp-pc system. multiple sprint work: physiological responses, mechanisms of fatigue and the influence of aerobic fitness. to ensure the blood glucose levels are healthy excess glucose that is not needed immediately to produce energy for the body is converted into a substance called glycogen and this is stored in the muscles and liver.
Responses to Anaerobic Exercise
is also known as creatine phosphate and like existing atp; it is stored inside muscle cells. the hydrolysis and resynthesis of atp is thus a circular processâatp is hydrolyzed into adp and pi, and then adp and pi combine to resynthesize atp. activity continues at a high intensity these stores may only partially replenish as there will not be enough energy available for creatine and pi to reform pc and the rate of atp breakdown through other energy systems will impede the replenishment of atp stores in the muscle. (1998) the relationship between repeated sprint ability and the aerobic and anaerobic energy systems. you train any of your clients at high intensity you must understand how this energy system works. (1994) with a group of subjects who performed 6 second sprints with recovery intervals from 15 to 180 seconds found that there is a 81% recovery in peak power output (ppo) with a 1 minute recovery and a 92% recovery of ppo in 3 minutes. contains four calories per gram and again provides energy at a much slower rate than carbohydrates. this happens you are starting to work on power endurance (as fatigue is evident) and that is counter productive if your goal is purely to increase the atp-pc system's capacity. in this case assists the synthesis of new atp rather than the breakdown. thus, the aerobic system produces 18 times more atp than does anaerobic glycolysis from each glucose molecule.
