In physical rehabilitation and sports training, the SAID principle asserts that the human body adapts specifically to imposed demands.[1] In other words, given stressors on the human system, whether biomechanical or neurological, there will be a Specific Adaptation to Imposed Demands (SAID).[2]

In 1958, Berkeley Professor of Physical Education Franklin M. Henry proposed the "Specificity Hypothesis of Motor Learning".
