Document Summary
Flexibility the ability of a joint move through its full range of motion. Refers to the achievable range of motion at a joint or group of joints without causing injury. Ss involves lengthening a muscle until either a stretch sensation or the point of discomfort is reached and then holding the muscle in a lengthened position for a prescribed period of time. Ds involves the performance of a controlled movement through the rom of the active joint(s). For a number of reasons, ds is sometimes considered preferable to ss in the preparation for physical activity. Pnf stretching incorporates ss and isometric contractions in a cyclical pattern to enhance joint. Rom, with 2 common techniques being contract-relax (cr) and contract-relax-agonist-contract (crac). (muscles, tendons, and ligaments: muscle connective tissue very important. Provides structure to muscle fibres, elasticity and bulk (~30% of muscle mass) Of practical importance, there was no evidence that stretching negatively influences injury risk.
