MICROANATOMY

Detailed explanation-1: -An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting (Lindstedt et al., 2001).

Detailed explanation-2: -Eccentric contraction occurs when the total length of the muscle increases as tension is produced. For example, the lowering phase of a biceps curl constitutes an eccentric contraction. Muscles are capable of generating greater forces under eccentric conditions than under either isometric or concentric contractions.

Detailed explanation-3: -Applying a warm compress or heating pad to the affected muscle to help relax rigid muscles. Gently stretching your stiff muscle to help relax it. Avoiding strenuous activity that may trigger the muscle to become rigid again. Encouraging the muscles to relax using massage, yoga, or tai chi.

Detailed explanation-4: -During a concentric contraction, the muscles that are shortening serve as the agonists and hence do all of the work. During an eccentric contraction the muscles that are lengthening serve as the agonists (and do all of the work).
