Muscle contractions happen when muscle fibers are stimulated‚ which can cause one of many types of contractions.

The biceps brachii the gets more tension‚ but the muscle length stays the same. As for isotonic

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)
