Measuring Intensity

Low, moderate and vigorous

The talk test

Low – should be able to sing

Moderate – should be able to comfortable carry out a conversation

Vigorous – talking will not be possible

RPE – Rate of Perceived Exertion

Target HR - % Max HR

Low intensity – less than 50% of MAX HR

Moderate intensity – 50% - 70% of MAX HR

Vigorous intensity – more than 70% of MAX HR

Max HR = (220 – age) OR 208 – (0.7 x age)

Metabolic Equivalent (MET) level

A more exact measure of intensity is the MET. ONE MET equals the energy (oxygen) used by the body as you sit quietly.

The harder your body works, the higher the MET level.

Low = less than 3 MET level

Moderate = 3 – 6 MET level

Vigorous = More than 6 MET level
