Acute Responses to Exercise Quiz

What is the primary purpose of the respiratory system during exercise?

• To deliver oxygen to the cells

• None of the above

• To remove carbon dioxide from the cells

• Both A and B

What is the formula for ventilation (V)?

• V = RR + TV

• V = RR x TV

• V = RR / TV

• V = RR - TV

• 1.5L/breath

• 2L/breath

• 1L/breath

• 0.5L/breath

What is the typical respiratory rate at rest?

• 6 breaths/min

• 12 breaths/min

• 18 breaths/min

• 24 breaths/min

What is the primary purpose of the cardiovascular system during exercise?

• Both A and B

• To remove carbon dioxide from the cells

• None of the above

• To transport more blood to the working muscles

What is the formula for cardiac output (Q)?

• Q = HR + SV

• Q = HR - SV

• Q = HR x SV

• Q = HR / SV

What is the typical cardiac output during maximal exercise?

• 4-5 L/min

• 20-30 L/min

• Diastolic blood pressure

• Systolic blood pressure

• Capillary pressure

• Venous pressure

What is the primary purpose of the muscular responses during exercise?

• To remove carbon dioxide from the cells

• To increase blood flow to the muscles

• To decrease energy substrates

• To increase lactate production
