Exercise and the Circulatory System
- Heart Rate
- Resting = around 72bpm
- Needs to be raised to 60% of
maximum to improve
cardiovascular fitness
- Maximum = 220 - age
- Time taken for heart
rate to return to resting =
recovery rate
- Resting = around 72bpm
- In prolonged aerobic events it is important that the
blood controls oxygen and glucose levels, waste
removal and body temperature so the performance
can be sustained for the duration of the event
- In anaerobic
respiration, glucose is
used immediately -
demand is controlled
by blood circulation
- After high intensity exercise,
lactic acid is removed via the
circulatory system which then
relieves cramp/fatigue
- Effects of regular exercise and training
- Endurance or aerobic helps strengthen the heart
- Size of heart increases; walls become thicker, stronger and more robust
- Rest stroke volume increases
- Resting heart rate is lower
- Slower bmp = more efficient heart is at pumping
required amount of blood with fewer beats
- Slower resting heart rate
= fitter the person is
- Slower resting heart rate
= fitter the person is
- Slower bmp = more efficient heart is at pumping
required amount of blood with fewer beats
- A person with good aerobic fitness is able to keep working efficiently without tiring or losing skill
- Endurance or aerobic helps strengthen the heart
