Document Summary

The ability to move a joint fluidly thru its full range of motion (rom) Flexibility of a joint is affected by: Static flexibility: ability to hold an extended position at one end of a joint"s range of motion. Dynamic flexibility: ability to move a joint through its full range of motion with little resistance. Nerves that detect changes in length & tension, resulting in contraction or relaxation. Muscle spindle -- respond to changes in length in muscle fibers. Golgi tendon organ (gto) -- respond to changes in tension within muscle groups. Muscles are stretched suddenly in forceful, bouncing movements. Slow, gradual stretches to the point of slight tension, holding for 10-30 seconds. Reduced receptor response, which increases the depth of stretch. Intensity: stretch to the point of mild discomfort, not pain, & relax/breathe easily. Frequency: at least 2-3 days/week (max of 7) Volume: 2-4 repetitions; 60 secs each stretch. Progression: build flexibility slowly, through full rom.
