Heart rate, stroke volume and cardiac output

• Heart Rate (HR)


  number of times that the heart or ventricles, beats in a minute, measured in bpm
• Stroke Volume (SV)


  The amount of blood ejected from the heart (per beat), measured in ml
• Cardiac output (Q)


  The amount of blood ejected from the heart (per minute), measured in ml

  )To calculate HR x SV = Q
• untrained values (HR)


  Rest - 70bpm

  Sub max - 120bpm

  Maximal - (220 - age)
• Untrained values (SV)


  Rest - 70ml

  Sub max - 120ml

  Maximal - 120ml
• Trained values (HR)


  Rest - 50bpm

  Sub max - 100bpm

  Maximal - (220-age)
• Trained values (SV)


  Rest - 100ml

  Sub max - 200ml

  Maximal - 30l/min
• Cardiac output values (all)

  Rest - 5l/min

  Sub max - 15l/min

  Maximal - 30l/min
• Submaximal exercise


  Exercise is at a low to moderate intensity within a performers aerobic capacity - e.g jogging
• Maximal exercise


  High intensity above a performers aerobic capacity to exhaustion , e.g sprinting
