energy systems Flashcards
what is the ATP-PC system
The ATP-PCr energy system is the immediate source of ATP for muscle action. It will provide energy at maximum intensity, but for a short duration (8-10 seconds).
what is the anaerobic energy system
The anaerobic energy system uses glycogen and glucose to produce ATP without requiring oxygen.
what is the aerobic energy system
The aerobic energy system uses oxygen to produce ATP. Stored fats and carbohydrates are the fuel source for this energy system.
how long does the ATP-PC last system
10 secs
when is the anaerobic system used
The anaerobic energy system produces ATP without using oxygen and relies on the breakdown of glucose. It kicks in after the ATP-PCr system is depleted, providing energy for 1-2 minutes of high-intensity effort.
A 400m runner utilizes the anaerobic glycolytic system to maintain speed over the duration of the race.
when is the aerobic energy system used
The aerobic system uses oxygen to produce ATP and is primarily used for long-duration, moderate-intensity activities. Fats and carbohydrates are broken down into glucose and fatty acids, which are then used to produce energy.
how long does the anaerobic system produce energy for
around 90 secs
what by product is produced in anaerobic respiration
lactic acid
