Although pedometers are widely used to measure physical activity by counting the number of steps a person takes, they canât measure exercise intensity. In the lab, exercise intensity is commonly determined by measuring the amount of oxygen taken in by the body during exercise, known as oxygen uptake.
Absolute intensity. The amount of energy used by the body per minute of activity. See Measuring Physical Activity for more. Aerobic physical activity.
