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.
Once you know your maximum heart rate, you can calculate your desired target heart rate zone â the level at which your heart is being exercised and conditioned but not overworked. Here's how heart rate matches up with exercise intensity levels: 1  Moderate exercise intensity: 50 to 70 percent of your maximum heart rate.or example, say your age is 45 and you want to figure out your target heart rate zone for vigorous intensity exercise. Subtract 45 from 220 to get 175 â this is your maximum heart rate. To get the lower end of your target zone, multiply 175 by 0.7 to get 123. To get the higher end, multiply 175 by 0.85 to get 149.
