    Can you give an example of the use of different energy systems?

    Use of energy systems: example That is not to say the other systems are not working; however, their role is minimal (remember that all three energy systems are working at one time. They do not switch on and off on demand). Also, because you are working at a low intensity, your aerobic system is burning glycogen and fat. As you increase your walking intensity, the aerobic system increases (Krebs cycle spins faster) to meet the demand. Because all three energy systems are working, the aerobic system is also working to break down the small amounts of lactic acid produced (which it does in the Krebs cycle). The aerobic system also works to restore PC stores. As you increase your running speed and increase intensity further, you get to a point where the aerobic system starts to struggle to supply enough energy. You are pumping as much O2 down into the muscles as possible and the Krebs cycle is spinning flat out. It is providing maximal energy for ATP production and providing energy to break down lactic acid that is being accumulated by the LA system. If you increase intensity even further beyond this point, the only way the body can supply energy is through additional use of the LA system. The result is that lactic acid begins to accumulate. This is because the aerobic system is working maximally and is unable to break any more lactate being produced over and above what is commonly referred to as the anaerobic threshold.
