A woman is training to improve her running capabilities for an upcoming marathon. She is progressively increasing the distance and time of her runs. Which principle best explains physiological adaptions occuring to the woman's aerobic energy system?

a. Autogenic inhibition

b. Mechanical specificity

c. Reciprocal inhibition

d. Metabolic specificity

Metabolic specificity is the best explanation of physiological adaptation occuring to the woman's aerobic energy system.

Explanation:

Metabolic specificity refers when energy is needed on the body to develop endurance. This is achieved through training that includes exercise, running etc.

This type of training use aerobic pathway which supply the necessary energy for the body.

This increases muscular strength, power etc.

Training requires rest for longer period to increase the intensity of the exercise.

This type of training burn the fat and thus it provide extra calorie.
