On this page you'll learn how this system will keep you chugging along forever without ever letting you get out of 2nd gear!
It is useful for your progression to know how these systems work and how you can improve their efficiency. Two of the systems are Anaerobic Non-oxidative meaning the body uses stored resources and does not need oxygen to work, while the third is Aerobic Oxidative meaning the body needs oxygen to aid in energy production.
ATP Adenosine Triphosphate is the fuel used and the effect can be slightly lengthen by combining with CP Creatine Phosphate to allow a duration of around seconds.
Training this system involves maximal efforts of about seconds and then resting for around times that amount.
Once the ATP-CP system is used up and does not have time to recover, the body will utilise muscle glycogen to fuel energy.
The breakdown of the glycogen leads to lactate accumulating in the muscles, causing them to fatigue. This system is used in training such as a m Row or Tabata Squats.
Unlike the other two systems, aerobic work is fuelled through the use of oxygen to breakdown carbohydrate, fat and eventually protein.
The Aerobic system is used for more moderate to low intensity work, but can be sustained for a long period of time, think a 5km Run, or a light weight 20min timed workout.
Training should consist of longer non-stop efforts at a steady pace or shorter moderate intensity intervals with little rest. Please leave any questions in comments or ask me next time you are in the gym!"While one energy system will predominate over the other, both aerobic and anaerobic energy systems are always working, regardless of intensity or type of activity" (Brooks, , p.
). The relative contributions of each energy system are dependent upon both the exercise intensity and duration (McArdle, et.
ATP-CP System: This system is used for short powerful bursts of energy, think 1RM Power Clean, or 40m Sprint. ATP (Adenosine Triphosphate) is the fuel used and the effect can be slightly lengthen by combining with CP (Creatine Phosphate) to allow a duration of around seconds. As the name suggests the ATP-PC system consists of adenosine triphosphate (ATP) and phosphocreatine (PC). This energy system provides immediate energy through the breakdown of these stored high energy phosphates. The ATP-CP system is also known as the phosphate energy system, the phosphocreatine system and the phosphagen system. The aerobic system provides energy for the resynthesis of ATP through the breakdown of various energy fuels (mainly glycogen and fats) through a series of chemical steps that require oxygen.
al., ; Newsholme, et. al., ). well the three energy systems used to rebuild ATP are 1 the ATP-PC system 2 the Lactic acid system 3 the Aerobic system both 1 and 2 are anerobic and 3 is aerobic.
The aerobic energy system utilises fats, carbohydrate and sometimes proteins for re-synthesising ATP for energy use. The aerobic system produces far more ATP than either of the other energy systems but it produces the ATP much more slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.
Energy System Interplay. Refers to the concept that more than one energy system is contributing to ATP resynthesis at one time. Fats. found in muscle tissue and the liver. A major energy source for the Anaerobic Lactic Acid System and Aerobic System.
Glycolysis. The breakdown of glycogen. Intensity (Aerobic System) Low - Medium . This system produces ATP copiously and is the prime energy source during endurance activities When working at 95% effort these energy pathways are time-limited .
ATP Resynthesis The energy for all physical activity comes from the conversion of high-energy phosphates (adenosine triphosphate—ATP) to lower-energy phosphates (Robergs & Roberts ). Thus, the aerobic system produces 18 times more ATP .
