- 1. Multiple Choice
Acute responses to exercise occur:
Prior to exercise
During exercise
In the recovery phase
All of the above
- 2. Multiple Choice
Ventilation is:
Tidal volume x Cardiac output
Stroke volume x Heart rate
Tidal volume x Respiratory rate
Stroke volume x Respiratory rate
- 3. 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
- 4. Multiple Choice
Cardiac output is:
Tidal volume x stroke volume
Stroke volume x heart rate
Heart rate x ventilation
Stroke volume x venous return
- 5. Multiple Choice
The redistribution of blood flow during exercise increases to the:
Kidneys
Liver
Brain
Muscles
- 6. 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
- 7. 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
- 8. 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
- 9. 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
- 10. 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
- 11. 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
- 12. 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
- 13. Multiple Choice
Which athlete would have the highest VO2 Max:
Netball player
AFL midfielder
Cross Country Skier
Olympic diver
- 14. Multiple ChoiceWhat does an acute response mean?Long Term ResponseImmediate Response
- 15. Multiple Choice
What does the Musculoskeletal System consist of?
Lungs, tendons, ligaments, bones and cartilage
Muscles, heart, ligaments, bones and cartilage
Muscles, tendons, ligaments, bones and cartilage
- 16. Multiple ChoiceWhat is the advantage of our muscles becoming more pliable as we exercise?We are able to sprint fasterOur muscles are strongerReduces the risk of injuryOur muscles are more resistant to fatigue
- 17. Multiple Choice
Why does the body transport more blood to our working muscles as we exercise?
Because too much CO2 needs to be removed.
Because the muscles need oxygen to carry on working.
It is needed to stop lactic acid forming.
It is needed to make our muscles stronger.
- 18. Multiple ChoiceCARDIAC OUTPUT IS...The number of times the heart beats in one minute.The amount of blood ejected by the left ventricle per beat.The amount of blood pumped out of the heart in one minutePressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
- 19. Multiple Choice
HEART RATE...
Stays constant from rest to exercise.
Slightly decreases during exercise, because stroke volume increases.
Increases during exercise.
Always goes straight to maximum during any exercise = 220 minus age.
- 20. Multiple Choice
REDISTRIBUTION OF BLOOD FLOW...
During exercise, blood flow is redirected away from the spleen, kidneys, guts and inactive muscles so that working muscles receive a greater % of Q.
Is pressure in the arteries following contraction of ventricles as blood is pumped out of the heart.
During exercise does not change. All organs continue to receive a consistent percentage of cardiac output.
- 21. Multiple ChoiceVENOUS RETURN IS...The blood returning to the heart via the inferior and superior vena cava.The number of breaths taken in one minute.The blood returning to the heart via the inferior and superior vena cava.During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
- 22. Multiple ChoiceVASOCONSTRICTION IS...A increase in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.A increase in the diameter of a blood vessel, resulting in a increase in blood flow to the area supplied by the blood vessel.A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.A decrease in the diameter of a blood vessel, resulting in no change in blood flow to the area supplied by the blood vessel.
- 23. Multiple ChoiceVASODIALATION IS...A increase in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.A increase in the diameter of a blood vessel, resulting in a increase in blood flow to the area supplied by the blood vessel.A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.A decrease in the diameter of a blood vessel, resulting in no change in blood flow to the area supplied by the blood vessel.
- 24. Multiple ChoiceDIFFUSION IS...How much air is inspired or expired in one breath.The number of breaths taken in one minute.(VO2 )The volume of oxygen that can be taken up and used by the body per minute.The movement of molecules from an area of higher pressure to one of lower concentration.
- 25. Multiple ChoiceVENTILATION IS...How much air is inspired or expired in one breath.How much air is breathed in or out in one minute.The number of breaths taken in one minute.(VO2 )The volume of oxygen that can be taken up and used by the body per minute.
- 26. Multiple ChoiceTIDAL VOLUME IS...How much air is inspired or expired in one breath.How much air is breathed in or out in one minute.The number of breaths taken in one minute.(VO2 )The volume of oxygen that can be taken up and used by the body per minute.
- 27. Multiple Choice
RESPIRATORY RATE...
Is how much air is inspired or expired in one breath.
Is how much air is breathed in or out in one minute.
Is the number of breaths taken in one minute.
Is (VO2 ) the volume of oxygen that is be taken up and used by the body per minute.
- 28. Multiple Choice
OXYGEN CONSUMPTION IS...
How much air is inspired or expired in one breath.
During aerobic exercise, blood volume decreases. Plasma volume decreases rapidly in the first 5 minutes of exercise then stabilises.
The number of breaths taken in one minute.
(VO2 )The volume of oxygen that is taken up and used by the body per minute.
- 29. Multiple Choice
Arterio - Venous Oxygen Difference...
Decreases during exercise, because there is less oxygen in the veins compared to the arteries.
Stays the same during exercise, because the muscles are always extracting maximum amounts of oxygen from the blood.
Increases during exercise, because the muscles extract less oxygen from the blood.
Increases during exercise, because the muscles extract more oxygen from the blood.
