Acute Responses to exercise I

Acute responses are referred to as

• The indefinite responses that last only for the duration of the activity

• The long-term responses that last only for the duration of the activity

• The immediate short-term responses that last only for the duration of the activity

• The long-term responses that last only for months after the completion of activity

Acute responses to exercise act at the

• superficial skin, muscular, cardiovascular and respiratory level

• muscular, cardiovascular and respiratory level

• digestive, muscular, cardiovascular and respiratory level

• visual, muscular, cardiovascular and respiratory level

Which of the following is not an acute response to exercise

• Increased blood volume

• Decreased blood volume

• Increased systolic blood pressure

• Decreased PC stores

Which of the following is an acute respiratory system response to exercise?

• increased blood flow to working muscles

• increased avO2 diff

• increased cardiac output

• increased ventilation

Acute responses of the respiratory system to exercise are designed to:

• facilitate an increase in the availability of H+ and the removal of carbon dioxide

• facilitate an decrease in the availability of oxygen and the removal of carbon dioxide

• facilitate an increase in the availability of oxygen and the removal of carbon dioxide

• facilitate an decrease in the availability of H+ and the removal of carbon dioxide

Ventilation =

• Stroke volume (millilitres) X RR (breaths per minute)

• Tidal volume (litres) X RR (breaths per minute)

• Tidal volume (litres) X HR (beats per minute)

• Respiratory Rate (Breaths per minute) X HR (beats per minute)

Ventilation is

• The amount of air breathed in and out per minute. The product of Tidal Volume (TV) x Respiratory Rate (RR)

• The amount of air breathed in and out per minute. The product of Tidal Volume (TV) x Heart Rate (HR)

• The amount of air breathed in and out per minute. The product of Stroke Volume (SV) x Heart Rate (HR)

• The amount of air breathed in and out per minute. The product of Pulmonary Diffusion (PD) x Heart Rate (HR)

Tidal volume is:

• the amount of air expired in one minute

• the amount of air expired in one breath

• the amount of air inspired in one breath

• the amount of air expired in two breaths

At sub-maximal intensity ventilation will

• Increase

• Decrease

• Stay the same

• Lower

Pulmonary diffusion refers to:

• Gas exchange occurs in the heart at the ventricular capillary interface and the respiratory capillary interface

• Gas exchange occurs in the heart at the ventricular capillary interface and the respiratory capillary interface

• Gas exchange occurs in the heart at the alveolar- capillary interface and the heart capillary interface

• Gas exchange occurs in the lungs at the alveolar- capillary interface and the muscle capillary interface
