Consider Option D: “How does a 20-minute cycling session affect cardiac output?”

  • Specifically identifies both the aerobic training stimulus (20-minute cycling) and the physiological response being measured (cardiac output).

Other Options:

  • A is incorrect: Measures participation rates, not physiological responses.
  • B is incorrect: Examines popularity of activities, not physiological responses.
  • C is incorrect: Investigates psychological preferences, not physiological responses.
