Document Summary
Possible reduction in low back pain (current or future) The ability of a joint to move freely through its full range of motion without causing injury. Can be joint specific: types of flexibility . Static range of motion achieved through slow, controlled movement. Dynamic range of motion achieved by quickly moving limb to its limits. Should be done at the end of the workout. Moving body parts to gradually increase speed and / or range of motion. Best done before activities that require high muscular forces. Provides 47% of resistance to move within joint. Can remain flexible with regular activity and stretching. Uses your own muscles forces to stretch yourself. Uses someone or something else to assist with a stretch (body, weight, gravity, strap or leverage. Proprioceptive neuromuscular facilitation (pnf) uses the nervous and muscular systems to facilitate stretching. Pnf stretch pattern: 10-30 second static stretch, 6 second isometric contraction of the muscle being stretched, 10-30 second passive-assisted stretch.
