and unfamiliar exercise‚ particularly which involves eccentric muscle actions can cause muscle damage and lead to delayed-onset muscle soreness (DOMS)‚ which may impair performance. This is due to the high force features of eccentric contraction (Starbuck & Eston‚ 2011). It can also cause muscle shortening‚ swelling and loss of strength in the muscles. Injuries commonly occur during eccentric loading of the muscle; that is‚ when the muscle is contracting while it is lengthening. (LaStayo‚ et al.‚ 2003)

causes the contraction or shortening of skeletal muscle. Muscles contract and shorten and as a result of this they are responsible for the movement of the body. In order to have movement the body needs ligaments‚ tendons muscles‚ joints‚ bones and the neurotransmitter or message sent for movement. Skeletal muscles that produce movement occurs at any given joint‚ only one of the articulating bones will move. The point of articulation‚ or where the muscles and the bones connect‚ is known as a joint.

Your elbow is a hinge joint. Your biceps and triceps muscles are basically two people standing on opposite sides of a wall (the humerus‚ or upper-arm bone)‚ each with one hand reaching over to its respective side of a door (the bones of the lower arm). The biceps "shuts" the door‚ by contracting and lessening

Nutrition A Muscle Contraction Muscle Contraction is part of an organ in the body that is tensive. It may have a process of tensions that may be developed with muscle tissues. Contraction can be a meaning of shortening or long. Muscle Contraction can also produce a muscle cell that is for movement of the body.
