Energy systems Flashcards
(16 cards)
Where does energy come from?
Adenosine Triphosphate (ATP)
How is energy produced?
Through ATP resynthesis (ATP is broken down to produce energy)
What is ATP?
It is a chemical fuel, give us energy.
Where do we get more ATP from?
ATP is constantly replenished/resynthesized through different fuels using the three energy systems
ATP can be replenished with or without oxygen:
Aerobic metabolism – is the process of ATP resynthesis with the presence of oxygen
Anaerobic metabolism – is the process of ATP resynthesis without the presence of oxygen
What fuels help with ATP resynthesis?
ATP can be replenished through these fuels:
Phosphocreatine (PC)/Creatine Phosphate (CP)
Carbohydrates
Proteins
Fats
What is the ATP-PC energy system fueled by?
PC (phosphate creatine)
ATP-PC is characterised by:
Very short/fast chemical reaction
Very small energy yield per molecule
Maximal intensity
What is the fuel for anaerobic systems?
CARBS
Anaerobic energy system is characterised by:
Medium length chemical reaction for anaerobic
Complex chemical reaction for aerobic
Large energy yield per molecule
Can be used at submaximal or near-maximal intensity
What is the fuel for the aerobic energy system?
Fats
Aerobic energy system is characterised by:
Needs a lot of oxygen
Complex, long chemical reaction
Highest energy yield per molecule
Can only be used at submaximal or at rest only
What is the last resort for fuel for energy?
Protein.
What energy system requires oxygen?
Aerobic system
What energy systems do not require oxygen?
ATP-PC and anaerobic system.
What does I DRY stand for?
I- INTENSITY
D-DURATION
R-RATE
Y-YEILD
What is the first sentence of the interplay questions?
During …….., all three energy systems will supply energy at different contributions depending on intensity and duration.
