Document Summary
Flexibility- the ability of a joint to move through its full range of motion (rom) (rom- full motion possible in a joint) Promotes good joint health (improves quality of life) Improves performance in sports and other everyday activities. Joint structure: primary determinant of how flexible a joint is (hinge vs. ball. Muscle elasticity and length (muscle can be lengthened if stretched regularly) Stretch receptors control the length of muscles (muscle spindles & golgi tendon organ) Primary limitation to flexibility: bone to bone. Movement requires that muscles cross a joint. Static stretching: each muscle is gradually stretched and held for 10-30 seconds. Ballistic stretching: sudden stretching in a bouncing movement. Active: stretching of muscles due to contraction of opposing muscles. Passive: muscles are stretched by outside force. At least 4 repetitions of each stretch. Frequency: minimum of 2-3 days per week. Body composition: the body"s relative amount of fat and fat free mass. Bone, water, muscle, connective tissue, organ tissues, teeth.
