Acute responses to exercise occur:

• Prior to exercise

• During exercise

• In the recovery phase

• All of the above

Acute respiratory responses to exercise do not include:

• Ventilation

• Cardiac Output

• Tidal Volume

• Pulmonary Diffusion

Ventilation is:

• Tidal volume x Cardiac output

• Stroke volume x Heart rate

• Tidal volume x Respiratory rate

• Stroke volume x Respiratory rate

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

What Cardiovascular Acute Response does not usually increase throughout exercise?

• Diastolic blood pressure

• Systolic blood pressure

• Stroke volume

• Heart rate

Cardiac output is:

• Tidal volume x stroke volume

• Stroke volume x heart rate

• Heart rate x ventilation

• Stroke volume x venous return

What is the only Cardiovascular Acute Response that decreases during exercise?

• Cardiac output

• venous return

• Blood volume

• Stroke volume

The redistribution of blood flow during exercise increases to the:

• Kidneys

• Liver

• Brain

• Muscles

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

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
