Awoman 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?

The correct answer would be metabolic specificity.

Metabolic specificity is one of the principles of the strength and conditioning of the body.

It deals with the energy demands of the body.

To develop endurance one must include long bouts of exercise with very less duration of rests in between the sets.

In contrast, one must take longer rest periods to develop maximal power and strength. Longer rest periods help in increasing the intensity of each bout.
