Acute physiological responses to exercise

What is the definition of VO2 max?

• The volume of oxygen transported to, taken up by, and used by the body for energy

• The maximum amount of oxygen per minute that can be taken in, transported, and utilized by the body for energy production

• The amount of oxygen consumed during the recovery period after exercise

• The discrepancy between oxygen supply and the oxygen needed to meet energy requirements

What is oxygen deficit?

• The state where oxygen supply meets oxygen demand

• The amount of oxygen consumed during the recovery period after exercise

• The state in which there is a discrepancy between oxygen supply and the oxygen needed to meet the energy requirements of the activity

• The volume of oxygen transported to, taken up by, and used by the body for energy

What is steady state in terms of oxygen uptake?

• The point where oxygen supply meets oxygen demand

• The amount of oxygen consumed during the recovery period after exercise

• The state in which there is a discrepancy between oxygen supply and the oxygen needed to meet the energy requirements of the activity

• The maximum amount of oxygen per minute that can be taken in, transported, and utilized by the body for energy production

Which of the following factors affects VO2 max?

• Body size

• Gender

• Age

• All of the above

Which system adjustments help to increase oxygen supply during exercise?

• Decreased heart rate and stroke volume

• Increased breathing rate and tidal volume

• Decreased enzyme activity

• Increased muscle substrate levels

What is the role of EPOC in the recovery period after exercise?

• To decrease muscle temperature

• To restore the body to its pre-exercise state

• To increase oxygen deficit

• To decrease oxygen uptake

Which factor does NOT affect EPOC?

• Muscle temperature

• Mitochondria activity

• ATP & CP restoration

• Body size

What is the primary function of VO2 during exercise?

• To decrease oxygen uptake

• To increase muscle temperature

• To ensure ATP production at the muscle level

• To decrease heart rate

What is oxygen deficit?

• The excess oxygen consumed after exercise

• A temporary shortfall in oxygen supply at the start of exercise

• The total oxygen used during a workout

• The difference between tidal volume and ventilation rate

What is EPOC?

• The increase in heart rate during exercise

• The oxygen consumed post-exercise to return to resting levels

• The total energy expenditure during exercise

• The decrease in oxygen uptake after exercise
