Principles of adaptations to stress: guidelines related to managing the application of stress during physical activity/exercise. Overload Principle: a principle of adaptation to stress suggesting the amount of stress applied during exercise must exceed a threshold level to stimulate adaptation. Volume: the term used to describe ―how much‖ stress is being applied by combining the duration and frequency of exercise. Progression principle: a principle relating to how much additional stress that can safely be introduced to gradually improve fitness without risking injury or overuse. Specificity: the principle of stress suggesting activities should be closely centered around the primary outcome goal, i.e. train the way you want to adapt.
