AOS2: ENERGY SYSTEMS Flashcards
(22 cards)
Discuss the RATE of each Energy System.
ATP-PC: Explosive/Rapid Rate
Anaerobic Glycolysis System: Medium Rate
Aerobic Glycolysis System: Slow Rate
Discuss the YIELD of each Energy System.
ATP-PC: Small Yield (0.7 mol/ATP)
Anaerobic Glycolysis System: Small Yield (2-3 mol/ATP)
Aerobic Glycolysis System: Large Yield (36-38 mol/ATP)
In addition Glycolysis uses 441-460 when using Fats
What are the FUELS of each Energy System?
ATP-PC: Chemical Fuel
Anaerobic Glycolysis: Food Fuel (Carbohydrates)
Aerobic Glycolysis: Food Fuels (Carbohydrates, Fats & Protein)
When is the PEAK ENERGY PRODUCTION for each Energy System?
ATP-PC: 4 second mark
Anaerobic Glycolysis: 5-15 second mark
Aerobic Glycolysis: 75 second mark
Where are Carbohydrates are stored and in what form are they stored as?
Carbohydrates are stored in the BLOOD (as GLUCOSE), MUSCLE (as GLYCOGEN) and LIVER (as GLYCOGEN).
Where are Fats stored and as what form?
Fats are stored in the BLOOD, MUSCLE AND AROUND THE BODY. They are stored as FREE FATTY ACIDS, TRIGLYCERIDES AND ADIPOSE TISSUE.
Where is Protein stored and as what form?
Protein is stored in the MUSCLE as AMINO ACIDS
What is the capacity of each Food Fuel last?
Capacity is how long something lasts
Carbs: 90-120 minutes (Limited)
Fats: Unlimited
Protein: Unlimited
What is Lactate Inflection Point (LIP)?
LIP is the point during exercise when the body cannot remove lactate quicker than the rate it is being produced.
How long does each Energy System last for?
ATP-PC: Lasts for approximately 10-12 seconds.
Anaerobic: Fatigues after approximately 2-3 minutes
Aerobic: Virtually Unlimited (due to constant supply of Oxygen).
What Food Fuel is a preferred source for the Aerobic Glycolysis System? why?
Carbohydrates are the preferred Food Fuel. Fats can produce more Energy, but they require more oxygen to be broken down.
What is the Formula for the Anaerobic Glycolysis System?
Glycogen
|
Glucose
|
Pyruvate
|
Lactic Acid
/ \
Lactate Hydrogen Ions
This process can work both ways, with Lactic Acid able to break down into Glycogen and start the process again.
Recovery is defined as ________________
Recovery is defined as returning your body to PRE EXERCISE STATE
What is Passive Recovery and when is it ideally used?
Passive Recovery is a type of recovery that involves no movement. It is ideal for short events (such as Long Jump) where ATP stores can be replenished quicker during rest.
What is Active Recovery and when is it ideal?
Active Recovery is a VERY LOW INTENSITY type of recovery which can involve movements such as walking, jogging, dynamic stretching, etc. it is ideal for events where the Anaerobic Glycolysis System has been used and by-products such are Lactate is produced.
The ALACTACID PHASE is ____________
The immediate recovery phase after activity (3 minutes) and involves the replenishment of ATP/PC stores
The LACTACID PHASE is _____________
The slow recovery after exercise (several hours) where lactic acid is converted back to fuel and Hydrogen Ions are oxidised.
EPOC stands for:
Excess
Post Exercise
Oxygen
Consumption
Oxygen Deficit is when___________
Oxygen Demand is greater than Oxygen Supply
Oxygen Debt is when _________
Oxygen Supply is greater than Oxygen Demand
Steady State is when __________
Oxygen Supply is equal to Oxygen Demand
How long do ATP stores last and how long do PC stores last?
ATP stores last for 2 seconds, whilst PC stores last for approximately 10 seconds (12 seconds for elite athletes)
