Heart rate per minute
Age
To read the graph, simply nd your age on the horizontal axis and scan up the
vertical until you reach the 60%, 70% and 90% values.
Aerobic exercise performed at a heart rate between 60% and 70% mainly burns
fat as an energy source.
When doing aerobic exercise at a heart rate of 70% to 90% the cardiocirculatory
component prevails.
For example, if someone aged 30 wants to burn o fat, the heart rate during
exercise should be kept to between 112 (60%) and 131 (70%); if he or she wants
to improve cardio-respiratory capacity, the heart rate should be kept to between
131 (70%) and 168 (90%).
