Unit 3 AOS 2 How does the body produce energy

Physiological Response

100

What is the calculation for Ventilation?

Respiratory Rate x Tidal Volume

200

How do you calculate Maximum heart rate?

220-your age

300

Explain Steady State?

The state in which, oxygen supply equals oxygen demand. 

400

Define the term maximum oxygen uptake.

Maximum oxygen uptake (VO2 max) represents the maximum amount of oxygen able to be taken in, transported to and consumed by the working muscles to produce energy.

500

Discuss the factors that could determine the size of the oxygen deficit that accrues.  

• exercise intensity — the greater the intensity of the exercise, the greater the oxygen deficit as it takes longer for the oxygen supply to equal the oxygen demand of the exercise. 
• training status of the individual — for any given exercise intensity, a trained individual will attain steady state sooner than an untrained individual. The trained individual will accrue a smaller oxygen deficit than an untrained person.

Respiratory System response

100

Name one of the 4 responses to exercise?

Increased respiratory rate 

increased tidal volume

increase ventilation

increased pulmonary diffusion

200

What is the calculation of cardiac output?

Heart Rate x Stroke Volume

300

What is the estimated Heart Rate of a 16 year old?

204

400

Explain what is meant by the arteriovenous oxygen difference

The arteriovenous oxygen difference (a-VO2 diff) is a measure of the difference between the concentration of oxygen in the arterial blood and the concentration of oxygen in the blood in the veins

500

Explain the relationship between Cardiac Output and Oxygen Diffusion 

The higher the Cardiac output the more oxygen being transported to the working muscles.

Interplay

100

What is ATP?

Adenosine Triphoshate

200

What gets added together to make ATP?

ADP+PI+Energy

300

Explain the difference between Rate and Yield?

Rate is how quickly ATP or ADP is generated

Yield is how much is generated each time

400

Explain using sporting examples when the Anaerobic Glycolysis system is in play. 

Events that have short duration but high impact/intensity

500

Explain the relationship between intensity of aerobic exercise and relative use of carbohydrates and fats as fuel.

Higher the intensity of aerobic exercise, the greater the reliance on carbohydrates in preference to fats as the major fuel source.

fuel

100

What are the bodies 3 sources of energy?

Carbs

Fats

Protein

200

What happens to Carbs if they are not burnt off?

They turn into Fats

300

When is it best to be having Carbs as your main energy source?

24 hours before and during the event

400

What Percentages of Carbs, Fats and Protein are the recommended breakdown of energy source?

55-60% Carbs

20-25% Fats

15% Protein

500

When does protein become the main source of energy?

When completing in long distance/length of time events when starvation and dehydration occurs to produce ATP.
