An eccentric contraction is described as
A) action potential frequency is high enough that no relaxation of muscle fibers occurs.
B) a muscle produces constant tension during contraction.
C) a muscle produces an increasing tension during contraction.
D) a muscle produces increasing tension as it shortens.
E) a muscle produces tension, but the length of the muscle is increasing.
Eccentric Contraction
A type of muscle activation that increases tension on a muscle as it lengthens, commonly occurring during the lowering phase of a movement.
Muscle Tension
The condition in which muscles of the body remain semi-contracted for an extended period.
Contraction
The tightening of a muscle in response to a stimulus, which results in movement or tension.

Final Answer :
E
Explanation :
Eccentric contraction occurs when a muscle produces tension while it is being lengthened, not shortened. This is common in activities where the muscle controls the movement of a load in a downward or resisting motion, such as lowering a weight slowly in a controlled manner.
