ATP-PC SYSTEM
What does ATP stand for?
Adenosine Tri-phosphate
What is produced as a byproduct of anaerobic glycolysis?
Lactic Acid
What is the primary fuel source for the aerobic system during prolonged activities?
Carbs
How long can the ATP-PC system provide energy as the predominant energy system for high-intensity activities?
10-12 seconds
How long does anaerobic glycolysis typically last as the predominant energy system during intense exercise?
10-75/90 sec
Identify a sport that primarily utilises the aerobic system:
Marathon, triathalon, x-country skiing, distance swimming
Name a sport or activity that primarily uses the ATP-PC system
100m sprint (most common) *other answers accepted
Name a sport that predominantly relies on anaerobic glycolysis + justify why:
400m, soccer, basketball + many more
(any burst of high intensity sport)
What is the work:rest ratio for training the Aerobic System?
1:1, 1:2, 2:1
What is the work:rest ratio to target the ATP-PC system?
1:5 (or above!)
In terms of how ATP is created - explain the difference between anaerobic glycolysis and aerobic respiration:
anaerobic = ATP synthesis WITHOUT oxygen
aerobic = ATP synthesis WITH oxygen
Name 3 benefits of training the aerobic system:
- Increased ability to create ATP from oxygen (more energy)
- Faster recovery
- Increased mood
+ many more
What is different about the fuel source for the ATP-PC system to other systems' fuel sources?
As the by-products of the Anaerobic Glycolysis systems build up - > this causes a drop in WHAT? Which leads to muscle dysfunction
PH!!!!!! Hydrogen ions build up as a result of lactic acid, causing a drop in PH.
At what point does the Aerobic system switch from using primarily carbs for fuel -> fats?
