What is NOT one of the principles of the Physical Stress Theory of exercise prescription?

The principle of immobility does not align with the Physical Stress Theory, which emphasizes the importance of applying appropriate stress to the body to promote adaptation and improve physical function. Physical Stress Theory is concerned with how various levels of physical stress affect the body's biological responses, leading either to maintenance of function, improvement in capabilities, or, conversely, to detriment if stress levels are insufficient.

In contrast, the principles of overload, specificity, and progression are fundamental to exercise prescription under Physical Stress Theory. Overload refers to the need to apply a greater amount of stress than the body is accustomed to in order to stimulate physiological adaptations. Specificity addresses how the type of exercise performed determines the physical adaptations that occur, emphasizing the need for targeted training to achieve desired outcomes. Progression involves gradually increasing the intensity or volume of exercise to continue promoting adaptations, ensuring the individual does not plateau in their physical development.

Thus, immobility contradicts these principles, as it refers to a lack of movement, which does not foster the necessary stress for adaptation and improvement in physical function.
