The ability to sustain this energy system is commonly viewed as an important athletic attribute in team sports such as basketball, hockey, ringette, and soccer where shifts, or transitions, are a part of the game. Individual sports that consist of rallies or routines such as tennis, figure skating, gymnastics and skiing utilize this system. And finally, there are several events within particular sports that rely almost exclusively on this energy system such as rowing m , and middle distance runners mm.
The anerobic alactic system does not require oxygen, however, whereas the ATP-CP system will only produce energy for 10 seconds, fast glycolysis can work at a capacity for much longer. As a result, waste products such as lactic acid accumulate in the blood and in muscle cells. Focusing on this energy system during training can reduce the amount of lactic acid that builds up, and prolongs the ability to utilize this energy system.
For most of us, energy is something we only talk about when we run out of it during a game of tennis or touch footy. But how does it get there?
How do we get the energy we need to move the human body? So what are the three main energy systems? Energy system one — aerobic The aerobic energy system is also known as the oxygen energy system and it uses both carbohydrates and fat in a slow energy burn.
ATP-PC energy system Think of all those short, sharp bursts of energy such as a metre sprint or fast and furious bench press set. Lactic acid energy system So the aerobic energy system deals with our longer endurance energy needs and the ATP-PC system covers all the super short bursts.

This system is dominant at lower intensities and efforts lasting longer than 2 to 3 minutes. Production of energy , or ATP, occurs in the mitochondria of the muscle fibers. These ATP stores last only a few seconds after which the breakdown of PC provides energy for another seconds of activity.
Combined, the ATP - PC system can sustain all-out exercise for up to seconds and it is during this time that the potential rate for power output is at its greatest. Examples — The aerobic system is the dominant system for any sport or activity that lasts more than 3 minutes. This includes most team sports such as netball, soccer, rugby, and AFL as well as many individual sports such as m swimming, marathon running, cycling, triathlons, tennis and iron mans. The aerobic system can utilize three different fuels: fats, carbohydrates and proteins.
The bulk of the energy will come from fats and carbohydrates, and of these two, fats provide most of the fuel for daily activity. There are three energy systems : the immediate energy system , the glycolytic system , and the oxidative system. All three systems work simultaneously to a degree, but parts of the system will become predominant depending on what the needs of the body are.
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration 2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system. The energy systems work together to replenish ATP. The energy systems all work together at the same time to keep replenishing ATP.
HIIT is both aerobic and anaerobic. The work is predominantly anaerobic but to get there you are beyond lactate threshold which is the ceiling of the aerobic system too. So both energy systems are being conditioned. Make writing personal training programs easy with these custom designed exercise templates, and keep your clients focused and progressing.

On this page you'll learn how this system will keep you chugging along forever without ever letting you get out of 2nd gear!
The more complex the process - the longer it takes to produce ATP The three stages which will be discussed in greater detail are: 1. Aerobic glycolysis slow glycolysis 2. Krebs cycle also known as the citric acid cycle 3. Electron transport chain Aerobic slow glycolysis — Stage 1 Aerobic glycolysis is exactly the same series of reactions as anaerobic fast glycolysis, except it just has a different outcome because sufficient oxygen is present. Steps of aerobic glycolysis: Initially stored glycogen is converted to glucose.
Glucose is then broken down by a series of enzymes.
