An isometric 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 as the length remains constant.
D) a muscle produces increasing tension as it shortens.
E) a muscle produces tension, but the length of the muscle is increasing.

Isometric Contraction

Muscle contraction in which the length of the muscle does not change but the tension produced increases.

Action Potential

A temporary reversal of the electrical potential across the membrane of a nerve cell (neuron) that occurs when the cell generates a nerve impulse.

Muscle Fibers

The cells that make up skeletal muscles, capable of contracting to produce movement and force.
