Which of the following statements best explains why the same exercise program might conform to the principle of overload for one person but not for another? a. different individuals have different levels of physical fitness. b. physical activity only leads to increased health benefits when it is above normal levels. c. bodies adapt to increased physical demands placed upon them. d. the same exercise programs always conform to the principle of overload.

The statement “Different individuals have different levels of physical fitness” best explains why same exercise program might conform to the principle of overload for one person but not for the another.

Overload Principle is one of the seven laws of fitness and training. It states that a person adapts to stress thus gaining strength and endurance by putting more intensity, variation, time and duration gradually to a work out. It is a training principle that uses the concept of adaptation to improve one’s strength and endurance.

For example, when a person begins working out after being mostly sedentary, that person will see some quick improvements. However, as that person gets stronger or fitter, he or she must increase the intensity of his training in order to continue to see those improvements. Otherwise, if that person continues doing the same work out (lifting same weights for the same number of sets and reps, week after week) his body will have adjusted to the stress, there will be no more adaptations and he will be in a state where no further developments in the body take place.

Since the principle of overload relies on adaptation, the same exercise program for one person will not have the same effect when applied for another person because each individual has a different level of fitness, hence will adapt to the stress at a pace that is according to their current level of fitness.
