Chronic Physiological Adaptations of Exercise - Aerobic

Aerobic/Cardio exercises cause cardiac hypertrophy, which is:

• the decrease in muscle mass of the heart

• the increase in muscle mass of the heart

• the increase in muscles around the lungs

• the increase in muscle mass around the body

With exercise, the growth of the heart muscles occur mainly in which area?

• The right atrium

• The right ventricle

• The left ventricle

• The left atrium

What is Stroke Volume?

• The volume of blood stored in the left ventricle of the heart

• The increase in size and strength of the heart muscles

• The number of contractions of the heart in a minute

• The volume of blood ejected from each ventricle due to the contraction of the heart muscle

Compared to an untrained person, the stroke volume of a trained person will:

• Increase

• Decrease

• Stay the same

• None of the above

Which of the following affects a person's resting heart rate?

• fitness level

• stress

• medication

• weather

• all of the above

The average human heart beat per minute is

• 0

• 10-50

• 60-100

• 110-150

Systolic blood pressure is the blood pressure of the arteries when the heart contracts/beats. Diastolic blood pressure is the blood pressure of the arteries when the heart relaxes.

• True

• False

What happens to our blood pressure (during rest) if we're consistent with exercise?

• Increase

• Decrease

• Stay the same

• Explodes. BOOM!

Exercise causes this change in the lungs. Which of the following best describes this image?

• Increase in nerves around the alveoli

• Increase in capillaries around the left ventricle

• Increase in capillaries around the alveoli

• Increase of blood flow to the rest of the body

The increase in capillaries around the alveoli causes

• quicker and more efficient exchange of gases (oxygen and carbon dioxide)

• slower and poorer exchange of gases (oxygen and carbon dioxide)

• more efficient blood flow to the heart

• less efficient blood flow to the heart
