Which characteristic distinguishes eccentric contraction from concentric contraction?
A. Eccentric contraction occurs when muscle fibers shorten under maximum load.
B. Eccentric contraction combines isometric and concentric actions.
C. Eccentric contraction has no force generation at all.
D. Eccentric contraction occurs when the muscle lengthens while exerting force.
Answer (2)
Eccentric contraction is distinguished from concentric contraction as it occurs when muscles lengthen while exerting force against a resistance. This is the opposite of concentric contraction, where muscles shorten while generating force. In the context of the options provided, option D correctly describes this characteristic of eccentric contractions. ;
Eccentric contraction is characterized by the muscle lengthening while exerting force. In contrast to concentric contraction, where the muscle shortens, eccentric contractions generate force while resisting a load. The correct answer is option D.
