Stretching, defined as movement applied by an external/internal force used to increase muscle flexibly and/or joint ROM, stresses the connective and muscle tissues mechanically. It depends on the active and passive tension of the muscle, the musculo-tendinous unit, as well as the proprioceptors of the musculoskeletal system (i.e., muscle spindles and Golgi tendon organs). Although duration and frequency are important, the rate and magnitude of force (stretching intensity) is of greater significance, with too much force possibly being responsible for stimulating an inflammatory response. This is associated with both a mechanical and biochemical response, with the former characterized by a 'local reaction' at the site of stress resulting in the accumulation of leukocytes, and the latter referring to the release of pro-inflammatory cytokines signaling acute inflammation. In conjunction with stretching intensity, the influence of body position may directly or indirectly influence stretching intensity, for muscle and tendon tissue and their components (i.e., collagen) are known to respond to altered levels of activity.
