Exercise Physiology Concepts

The video tutorial covers the cardiovascular (CV) system, focusing on blood pressure, its types, and how it changes during exercise. It explains the differences between dynamic and static exercises and their effects on blood pressure. The tutorial also discusses blood distribution during exercise, cardiovascular adaptations like cardiac hypertrophy, and the significance of VO2 Max in fitness. The video concludes with a summary and resources for further learning.

What is the term for the force exerted against arterial walls when the ventricle contracts?

• Diastolic blood pressure

• Mean arterial pressure

• Systolic blood pressure

• Pulse pressure

Which blood pressure reading is considered high?

• 110/70 mm Hg

• 140/90 mm Hg

• 90/60 mm Hg

• 120/80 mm Hg

During dynamic exercise, what happens to diastolic blood pressure?

• It stays the same or slightly decreases

• It decreases

• It fluctuates randomly

• It increases

Which type of exercise involves isotonic muscle contractions?

• Dynamic exercise

• Static exercise

• Aerobic exercise

• Isometric exercise

What percentage of blood flow goes to the muscles during exercise?

• 20-25%

• 50-60%

• 80-85%

• 90-95%

How much blood is typically in the body at rest?

• 5 liters

• 3 liters

• 7 liters

• 10 liters

What is the term for the increase in the size and strength of the heart due to exercise?

• Cardiac hypertrophy

• Cardiac output

• Cardiac atrophy

• Cardiac dilation

What does an increased arterial-venous oxygen difference indicate?

• Oxygen is being stored in the muscles

• No change in oxygen usage

• More oxygen is being used by the muscles

• Less oxygen is being used by the muscles

What does VO2 max measure?

• Maximum heart rate

• Maximum volume of oxygen consumed

• Maximum blood pressure

• Maximum muscle strength

Which group generally has a higher VO2 max?

• Females

• Males

• Older adults

• Untrained individuals
