Outline the relationship between stroke volume and training intensity during exercise.   (3 marks)

Show Answers Only

Sample Answer

  • Stroke volume increases as exercise intensity increases, up to approximately 40-60% of maximum intensity.
  • Beyond this point, stroke volume tends to plateau even if intensity continues to increase.
  • At very high intensities, stroke volume may decrease slightly due to reduced ventricular filling time (as heart rate becomes very high).
