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
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
A person with good aerobic fitness is able to keep working efficiently without tiring or losing skill
