How to Measure Intensity
There are 2 different ways to measure Intensity – the level of effort (Relative) and the amount of energy (Absolute).
The level of effort required by a person to perform an activity. When using relative intensity, people pay attention to how physical activity affects their heart rate and breathing.
The talk test is a simple way to measure relative intensity. In general, if you’re doing moderate-intensity activity you can talk, but not sing, during the activity. If you’re doing vigorous-intensity activity, you will not be able to say more than a few words without pausing for a breath.
The amount of energy used by the body per minute of activity. The table below lists examples of activities classified as moderate-intensity or vigorous-intensity based upon the amount of energy used by the body while doing the activity.
• Walking briskly (3 miles an hour or faster, but not race-walking)
• Race walking, jogging, or running
