Contraction during muscle lengthening is called
A) eccentric contraction.
B) concentric contraction.
C) isometric contraction.
D) isotonic contraction.
E) all of the above

Question

Quizplus · Accepted Answer

Eccentric contraction occurs when the muscle lengthens while under tension. This type of contraction allows for controlled movement and deceleration of a load, such as when lowering a weight during a bicep curl. Contrarily, concentric contraction occurs when the muscle shortens while under tension, while isometric contraction occurs when the muscle contracts but does not change length. Isotonic contraction refers to a contraction where the tension in the muscle remains constant while the length changes. Therefore, only option A correctly describes contraction during muscle lengthening.
