While the frequency and duration of exercise are the same for all persons, exercise intensity is more complex because it can be expressed in absolute terms (METs, Kcal/min) and in relative terms (%VO2max, %1RM). Disagreement exists whether exercise intensity should be expressed relative to a maximal value (%VO2max, %HRmax) or to a submaximal value (% above or below the lactate or ventilatory threshold). The Importance of Exercise Intensity for Health and for Prescribing Exercise discusses the importance of exercise intensity for various health states, as well as its importance for prescribing exercise.
