- 1. Multiple Choice
Acute responses to exercise occur:
Prior to exercise
During exercise
In the recovery phase
All of the above
- 2. Multiple Choice
Acute respiratory responses to exercise do not include:
Ventilation
Cardiac Output
Tidal Volume
Pulmonary Diffusion
- 3. Multiple Choice
Ventilation is:
Tidal volume x Cardiac output
Stroke volume x Heart rate
Tidal volume x Respiratory rate
Stroke volume x Respiratory rate
- 4. Multiple Choice
Movement of O2 and CO2 from an area of high concentration to an area of low concentration is:
Ventilation
Redistribution of blood flow
Pulmonary diffusion
Increased blood flow to working muscles
- 5. Multiple Choice
What Cardiovascular Acute Response does not usually increase throughout exercise?
Diastolic blood pressure
Systolic blood pressure
Stroke volume
Heart rate
- 6. Multiple Choice
Cardiac output is:
Tidal volume x stroke volume
Stroke volume x heart rate
Heart rate x ventilation
Stroke volume x venous return
- 7. Multiple Choice
What is the only Cardiovascular Acute Response that decreases during exercise?
Cardiac output
venous return
Blood volume
Stroke volume
- 8. Multiple Choice
The redistribution of blood flow during exercise increases to the:
Kidneys
Liver
Brain
Muscles
- 9. Multiple Choice
What is the only muscular acute response to decrease during exercise?
Motor Unit and muscle fibre recruitment
Energy substrates
Lactate production
Blood flow to muscles
- 10. Multiple Choice
Myoglobin is responsible for:
Transferring oxygen from capillaries into the muscle cell
Respiration and the aerobic production of energy / ATP
Breaking down glycogen
Transferring CO2 back into alveoli from the blood
- 11. Multiple Choice
During exercise, the maximal stroke volume of an untrained individual is attained:
Immediately as exercise begins
Submaximal intensity
At maximal exercise intensity
The stroke volume remains relatively unchanged
- 12. Multiple Choice
A result of participating in a bout of high intensity exercise, which statement is most correct
Increase lactic adic levels, decrease muscle temperature
Decrease lactic acid levels, decrease muscle temperature
Increase lactic acid levels, increase muscle temperature
Decrease lactic acid levels, decrease muscle temperature
- 13. Multiple Choice
30sec of maximal exercise would result in which muscular response?
Increased glycogen stores
Decreased lactate levels
Increased use of free fatty acids
Decreased intramuscular glycogen
- 14. Multiple Choice
Maximal exercise will result in the following acute respiratory response:
Increased tidal volume
Increased rate of gaseous diffusion at the lungs
Decreased production of CO2
Increased systemic gaseous exchange
- 15. Multiple Choice
The period at the beginning of exercise when O2 demand is greater than O2 supply is known as:
EPOC
Oxygen deficit
Oxygen debt
Steady State
- 16. Multiple Choice
During exercise more blood is directed to the working muscles and this is achieved via:
Vasodilation of capillaries supplying muscle
Vasoconstriction of capillaries supplying muscle
Vasodilation of capillaries supplying the heart
Vasoconstriction of capillaries supplying the heart
- 17. Multiple Choice
Blood volume decreases during exercise as:
There is an increase in O2 being delivered to working muscle
A consequence of sweating, therefore a decrease in plasma
Lactate begins to accumulate faster than removal rate
There is an oxygen deficit
- 18. Multiple Choice
Which athlete would have the highest VO2 Max:
Netball player
AFL midfielder
Cross Country Skier
Olympic diver
