In my post, Health Benefits of Exercise: a grossly underutilised therapy, I have discussed the various health benefits associated with physical activity, as a result of which exercise is now aptly being recognised as ‘medicine’. However, to derive optimal health benefits from exercise, an exercise program needs to follow certain parameters, similar to drug prescription, such as frequency, dose (amount), time (duration) and type (of physical activity). In my post Exercise Prescription for Optimal Health Benefits, I have discussed the FITT-VP principles for exercise prescription. In this post, I shall be discussing ‘prescription for aerobic exercise’ based on the FITT-VP principles. Prescription for strength training as per FITT-VP factors will be discussed in the next post. Aerobic exercise is referred to in the literature, both scientific and lay, by various terms. In the scientific literature, it is referred to as cardiorespiratory endurance or aerobic endurance, while colloquially it is referred to as aerobic exercise or just aerobic, or cardio, or cardio exercises, or cardio workout. In this post, these terms will be used interchangeably.
