![]() (n.) The wrongful, and usually the forcible, carrying off of a human being as, the abduction of a child, the abduction of an heiress. (n.) The movement which separates a limb or other part from the axis, or middle line, of the body. This helps maintain balance in the joints, and it allows the muscles to stimulate both their contractibility and extensibility. Definition: (n.) The act of abducing or abducting a drawing apart a carrying away. In other words, when biceps contracts, triceps elongates (here biceps is the agonist, and triceps is the antagonist), but when triceps contracts, biceps elongates (here triceps is the agonist and biceps is the antagonist). Remember that just because a muscle is an agonist muscle at one time does not mean it is the agonist all the time. The thigh abduction and adduction machines are the two that act like giant Thigh-Masters, with upright bench seats and leg pads that you squeeze together or press apart. Another way to put this is that the medial rotation muscles need to be stretched and the lateral rotation muscles need to strengthened. ABDUCTION is the movement away from the bodys midline, while ADDUCTION is the movement towards the centerline of the body. This means that when your shoulder is stuck in medial rotation, when you continuously have your arms in a medially rotated position, the medial rotation muscles are shortened and the lateral rotation muscles are lengthened. So, following are muscle categories by action: While the agonist muscle contracts to perform an action, the antagonist muscle must extend or lengthen. ![]() This means that certain muscles work against one another to stabilize and balance their joints. Muscles have agonist/antagonist relationships with one another. There is one more thing about muscles we have to know.
