gradÂ·ed exÂ·erÂ·cise test. Multistage exercise testing (usually on treadmill or bicycle ergometer) in which exercise intensity is progressively increased (graded) through levels that bring the test subject to a self-imposed fatigue level. See: stress test, Astrand-Ryhming Cycle Ergometer Test.
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.
