Energy And Energy Sources

Question 1

Aerobic exercise

Answer 1

Uses oxygen for energy production
Includes activities that are long duration
Includes activities that are of a moderate intensity

Question 2

Anaerobic exercise

Answer 2

Does not use oxygen for production of energy
Includes activities that are of a short duration
Includes activities that are of a high intensity

Question 3

Fats

Answer 3

Energy source of aerobic exercise
They require oxygen to break down the fat into energy
They are slow to break down
Once broke down they give large quantities of energy

Question 4

Carbohydrates

Answer 4

They are an energy source for both aerobic and anaerobic activities
Do not need oxygen to breakdown down into glucose
Doesn’t give as much energy as fats
Quicker to break down and release more energy then fats

Question 5

Muscular system short term effects

Answer 5

Muscle fatigue
Build up of lactic acid
Oxygen deficit - during recovery oxygen is paid back to - replenish myoglobin stores with oxygen, remove lactic acid, allow energy stores in the muscle to be replenished

Question 6

CV system short term effects

Answer 6

Increased heart rate
Increase stroke volume
Increased blood pressure
Increased cardiac output
Vascular shunting occurs

Question 7

Respiratory short term effects

Answer 7

Increase depth of breathing
Increased rate of breathing
Increased gas exchange
Increase tidal volume
Oxygen deficit

Question 8

Cardiac output

Answer 8

Amount of blood pumped from the heart in one min
Stroke vol x heart rate

Question 9

Heart rate

Answer 9

Amount of time heart beats per minute

Question 10

Stroke volume

Answer 10

Amount of blood pumped from the heart in one beat
