When designing an exercise prescription for an individual it is important to consider the FITT-
VP principle. Each of these principles factor into the results a person would get from specific
types of exercises, whether it is aerobic, strength, flexibility, or neuromuscular in nature. FITT-
VP stands for frequency, Intensity, Type, Time, volume, and progression, respectively and each
can be manipulated based on the need of the individual or their goals. For example, we can make
the intensity more difficult by adding weight, time or tempo to the exercise, and this would also
elicit an eventual change over time to the body based on the SAID principle. Which is the
adaptations made physiologically by the body because of the outside stress(exercise) that you put
on it.
There are four types or modes of exercise you can do with an individual and all have different
effects on the body and different purposes as well. The American College of Sports Medicine
(ACSM) defines aerobic exercise as any activity that uses large muscle groups, can be
maintained continuously and is rhythmic in nature. An example of this type of training would be
anything like walking, running using cardiovascular machines etc. Aerobic also emphasizes the
use of oxygen to supply energy to the working muscles in order to gain a cardiac effect and make
the heart pump faster and more efficiently. Strength training or resistance training is another
mode of exercise that is designed to improve muscular fitness by exercising a
muscle or a muscle group against. Flexibility is defined as ROM of a joint or
group of joints, as per the skeletal muscles and not any external
forces ( 40 ). The flexibility of any given movable joint includes both static and
dynamic components. Static flexibility is the full ROM of a given joint because of
external forces.
