Energy Systems Flashcards
What is ATP?
Basic unit of energy that fuels a;ll of the acitivities that we participate in throughout the day
What is ATP-CP System
An immediate energy system that does not require 02.
What are the five steps of ATP
- Phosphate Breakdown
- Release energy
- Phos[ho creatine splits into P and C
- This also release energy
- Free phosphate rejoins ADP to rebuild ATP
Disadvantages and Advantages of ATP-CP System
Adv: Imediate supply of ATP < 1ATP, Explosive, no foodbreakdown needed. Dis: Limited by amount of P( Stored in the muscles, 2 sec of atp 8 seconds of PC
What type of recovery must occur for ATP-CP to be involved
Passive recovery
what is Anerobic Glycolysisystem?
relies on the breakdown of glycologen, in the absence of 02 to produce energy

NIGGA
How long does the anerobic glycolysisystem last for?
10-60 seconds 400 m sprint, 100 metre swim
What is the resysnthesis ?
Resynthesis, in essence, is the process of recreating or reconstructing a sound, or a substance, by synthesizing it again after a chemical reaction or analysisFast
What happens when fatigue sets in in the glycolysisystem?
Causes muscle to become more acidic, affecting muscular contractions
Advantages of anaerobic glycolysis system?
Resynthesis ATP quickly allowing for high intensity
Disadvantages of anaerobic glycolysis system?
Produce H+ ions that cause fatigue inlarge amount anom, slow recovery
What is aerobic glycolysis?
the breakdown of glycolegyn in the presence of oxygen to produce energy, carbon dioxide, water and heat
Fuel of aerobic glycolysis
Carbohydrate + Fat ( depending on intensity/ duration)
What intensity is needed for the aerobic glycolisis
during rest and at sub maximal intensisties 80% max HR
What is the duration of aerobic glycolisis?
Gradual increase in contribution as 02 becomes available predominant energy system after 30 - 60
aerobic glycolisis Rate of resynthesis?
Slow
What is the yield rate
36-38 ATP
What happen when the aerobic system is in action
when using the aerobic system predominantly,anyaceunlated lactic acid can be oxidised / removed or converted back into glycolegyn to be used again as an energy source.
