Physical Activity Programming & Exercise Prescription

• Activity "Dose Response"

  • aerobic activity should performed at moderate intensity (40 to 70% of VO2 max/HRR)
  • lower intensities present with minimal fitness benefits
  • fitness benefits are more important regarding cardiovascular health

  
• Rate Pressure Product:

  • HR x SBP = RPP
  • heart rate x systolic blood pressure = rate pressure product
  • an indirect measure of myocardial oxygen demand
  • e.g. HR of 160 bpm x SBP 140 mmHg = RPP of 22400
  • reproducibility of ischaemic threshold in determining setting exercise intensity
• Demand Vs Supply:

  • exercise training:
  • increases supply by improving coronary blood flow
  • decreases demand by reducing workload ie MVO2
