Q

Discuss the YIELD of each Energy System.

A

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

Q

Where are Carbohydrates are stored and in what form are they stored as?

A

Carbohydrates are stored in the BLOOD (as GLUCOSE), MUSCLE (as GLYCOGEN) and LIVER (as GLYCOGEN).

Q

Where are Fats stored and as what form?

A

Fats are stored in the BLOOD, MUSCLE AND AROUND THE BODY. They are stored as FREE FATTY ACIDS, TRIGLYCERIDES AND ADIPOSE TISSUE.

Q

What is Lactate Inflection Point (LIP)?

A

LIP is the point during exercise when the body cannot remove lactate quicker than the rate it is being produced.

Q

How long does each Energy System last for?

A

ATP-PC: Lasts for approximately 10-12 seconds.

Anaerobic: Fatigues after approximately 2-3 minutes

Aerobic: Virtually Unlimited (due to constant supply of Oxygen).

Q

What Food Fuel is a preferred source for the Aerobic Glycolysis System? why?

A

Carbohydrates are the preferred Food Fuel. Fats can produce more Energy, but they require more oxygen to be broken down.

Q

What is the Formula for the Anaerobic Glycolysis System?

A
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.

Q

What is Passive Recovery and when is it ideally used?

A

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.

Q

What is Active Recovery and when is it ideal?

A

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.

Q

The ALACTACID PHASE is ____________

A

The immediate recovery phase after activity (3 minutes) and involves the replenishment of ATP/PC stores

17
Q

The LACTACID PHASE is _____________

A

The slow recovery after exercise (several hours) where lactic acid is converted back to fuel and Hydrogen Ions are oxidised.

18
Q

EPOC stands for:

A

Excess
Post Exercise
Oxygen
Consumption

19
Q

Oxygen Deficit is when___________

A

Oxygen Demand is greater than Oxygen Supply

20
Q

Oxygen Debt is when _________

A

Oxygen Supply is greater than Oxygen Demand

21
Q

Steady State is when __________

A

Oxygen Supply is equal to Oxygen Demand

22
Q

How long do ATP stores last and how long do PC stores last?

A

ATP stores last for 2 seconds, whilst PC stores last for approximately 10 seconds (12 seconds for elite athletes)
