What happens to stroke volume during the immediate response to high-intensity exercise?

  1. Stroke volume decreases due to reduced venous return
  2. Stroke volume increases then plateaus at approximately 40 - 50% of maximum intensity
  3. Stroke volume gradually decreases as exercise duration increases
  4. Stroke volume remains unchanged from resting levels regardless of exercise intensity

\(B\)

Show Worked Solution
  • B is correct: Stroke volume increases then plateaus at moderate intensity

Other Options:

  • A is incorrect: Stroke volume increases not decreases during exercise
  • C is incorrect: Stroke volume plateaus rather than gradually decreasing
  • D is incorrect: Stroke volume increases from resting levels
