SAID Principle - Specific Adaptation To Imposed Demands

By Carolyn Kisner PT, MS and Lynn Allen Colby PT, MS on April 20th 2008

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 […]

Muscle Performance And Resistance Exercise

By Carolyn Kisner PT, MS and Lynn Allen Colby PT, MS on April 20th 2008

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 […]
