Energy Systems Flashcards
The adenosine triphosphate-phosphocreatine (ATP-PC) system
Uses energy released after the breakdown of Phosphocreatine
The lactic acid system
Uses energy released from when glucose is converted into lactate in a process called glycolysis
The aerobic system
Uses energy released from the breakdown of carbohydrates or fats using oxygen
Aerobic
Requires oxygen to take place
Anaerobic
Does not require oxygen to take place
ATP-PC system lasts for
10-12 seconds of short duration activities
ATP-PC system full recovery within
8 minutes
Pyruvate
A molecule produced by the breakdown of glucose
Acidosis
Lowering of the pH in any tissue, such as muscle cells or blood
The lactic acid system provides energy for
the resynthesis of ATP energy during high intensity with a moderate duration of 30-120 seconds
VO₂max
The volume of oxygen an individual can use to produce energy, measured in millimeters per kilogram per minute
Blood lactate
Lactate that appears in the blood as a result of anaerobic metabolism
Anaerobic metabolism
ATP production without the use of oxygen
Lactate threshold
The highest oxygen consumption or exercise intensity possible with a little increase in blood lactate concentration above resting levels
Excess Post- Exercise oxygen consumption (EPOC)
Increased rate of oxygen intake during recovery immediately following strenious activity
