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.
The exercise intensity should begin at a low to moderate level, depending on the fitness level of the client. As the client gains aerobic endurance intensity can be progressively increased. ACSM (1998) recommends an exercise intensity of 55-90% of maximal heart rate or 40-85% of heart rate reserve. The duration of activity will depend on the initial fitness level of the client and the clients preferred exercise intensity. The exercise prescription should begin with approximately 20 minutes of continuous exercise and may progress up to 60 minutes (ACSM 1998).
