Muscular flexibility is the ability of a joint to move freely through its full range of motion (ROM). Total ROM around a joint is highly specific and varies from one joint to the other (hip, trunk, shoulder), as well as from one person to the next. How flexible someone is depends on genetic factors and the level of physical activity. Beyond that, factors such as joint structure, ligaments, tendons, muscles, skin, tissue injury, fat, age, and gender influence flexibility of a joint.

On the average, women have more flexibility than men and seem to retain this advantage throughout life. Aging decreases flexibility. The most significant contributors to loss of flexibility are sedentary living and lack of physical activity. |
