APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In a bicep curl the bicep is the agonist on the way up when it contracts concentrically, and on the way down when it contracts eccentrically.

Detailed explanation-2: -For instance, a flexion of the arm necessitates a concentric contraction of the biceps brachii whereas the antagonist muscle, the triceps brachii, lengthens in an eccentric action.

Detailed explanation-3: -Concentric contraction occurs when the total length of the muscle shortens as tension is produced. For example, the upward phase of a biceps curl is a concentric contraction.

Detailed explanation-4: -For instance, during concentric elbow flexion, the biceps brachii contracts concentrically, whereas the antagonist muscle, the triceps brachii, contracts mildly eccentrically – to allow movement precision and control.

Detailed explanation-5: -Concentric contractions involve the muscle shortening under tension, and it is the most common form of muscular contraction. For example, the biceps concentrically contract during the upward phase of a bicep curl, or in the triceps during the upward phase of a push-up.
