\(B\)

Show Worked Solution
  • B is correct: During aerobic training, heart rate and cardiac output both increase immediately to supply working muscles with more oxygen.

Other Options:

  • A is incorrect: Heart rate increases not decreases during exercise.
  • C is incorrect: Ventilation rate increases (not decreases) during aerobic exercise.
  • D is incorrect: Both stroke volume and cardiac output increase during exercise.
