The level of effort required by a person to do 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. As a rule of thumb, 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.
Examples of moderate intensity activity:
- Walking briskly
- Bicycling slower than 10 miles per hour
- Tennis (doubles)
- Water aerobics
Examples of vigorous intensity activity:
- Race walking, jogging, or running
- Swimming laps
- Tennis (singles)
- Aerobic dancing (Zumba, etc.)
