Balance of Stability and Active Mobility
Control of the body during functional movement and the ability to perform functional tasks require a balance of active movement superimposed over a stable background of neuromuscular control. Sufficient performance of agonist and antagonist muscles about a joint contributes to the dynamic stability of individual joints. For example, a person […]

The SAID principle (specific adaptation to imposed demands) suggests that a framework of specificity is a necessary foundation on which exercise programs should be built. This principle applies to all body systems and is an extension of Wolff’s law (body systems adapt over time to the stresses placed on them). The SAID principle helps therapists […]

The three elements of muscle performance strength, power, and endurance can be enhanced by some form of resistance exercise. To what extent each of these elements is altered by exercise depends on how the principles of resistance training are applied and how factors such as the intensity, frequency, and duration of exercise are manipulated. Because […]
