Three exercise energy systems can be selectively recruited, depending on the amount of oxygen available, as part of the cellular respiration process to generate the atp for the muscles they are atp, the anaerobic system and the aerobic system adenosine triphosphate atp is the usable form of chemical energy for muscular activity it is stored in most cells, particularly in muscle cells.
Atp resynthesis is the process by which the body and its muscles produce atp atp is the main energy source of almost all living things, and while atp is not energy itself, it temporarily stores energy in its bonds to be released on demand humans resynthesize atp through three metabolic pathways. Aerobic energy system, which is dependent on oxygen, is the most complex of the 3 energy systems is responsible for most of the cellular energy produced by the body, however aerobic metabolism is the slowest way to resynthesize atp.
Start studying chapter 5: energy systems learn vocabulary, terms, and more with flashcards, games, and other study tools the concept that more than one energy system contributes to atp resynthesis glycolysis aerobic energy system alternative name.
Aerobic glycolysis has a slow rate of atp production and is predominantly utilized during longer-duration, lower-intensity activities after the phosphagen and anaerobic systems have fatigued it is important to remember that all three of these systems contribute to the energy needs of the body during physical activity. Energy sources and systems – fats, carbohydrates and proteins locations within the body, factors affecting their use, related to intensity and duration of the exercise, resynthesis of atp aerobic energy system– simplified biochemistry in the breakdown, release and regeneration of atp in glycolosis, the krebs cycle and electron transport.
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.
The three energy systems conventionally, there are three energy systems that produce atp: atp-pc (high power, short duration), glycolytic (moderate power/short duration), and oxidative (low power/long duration) all are available and “turn on” at the outset of any activity.
