Energy Sustems - AEROBIC ENERGY SYSTEM Flashcards
What is the difference between aerobic and anaerobic glycolysis?
Aerobic
- uses oxygen
- slower rate of energy production
- low intensity
- long duration
Anaerobic glycolysis
- doesn’t use oxygen
- high intensity
- 1-2 min duration
What wastes occur in the aerobic energy system?
Carbon dioxide (Co2)
Waht are the fuels for the aerobic system
Carbs
Fats
Protein
What does the aerobic system have the slowest rate of producing energy?
It has the most chemical reaction used to burn fuel
What intensity and duration does the aerobic system need?
Intensity = sub maximal Duration = long (1-3 hours)
What is sub maximal exercise
Low intensity
Which fitness component links to aerobic?
Long duration
Eg marathon running
Which muscle fibre type links to this system?
Slow twitch
- red muscle fibre
What is the mitochondria? What happens there?
It is an organelle found in most cells, in which biochemical processes of respiration and energy production occur.
Fuel (carbs,fats,protein) are burnt up and waste (Co2) is released to create energy
What do oxidative enzymes do?
Increase the rate at which ATP is produced aerobic ally
What causes fatigue in the aerobic system?
Depletion of glucogen
What sporting events predominantly use the aerobic system?
Long distance running
- marathon
- cross country, etc…
What does aerobic mean?
Uses oxygen
