Muscle tension is the force exerted by the muscle on a bone or other object. A muscle contraction is isometric if muscle tension changes, but muscle length remains the same. An example of isometric muscle contraction is holding a book in the same position. A muscle contraction is isotonic if muscle length changes, but muscle tension remains the same.

Arm wrestlers must contract muscles in their hands and arms, and keep them contracted in order to resist the opposing force exerted by their opponent. The wrestler whose muscles can contract with greater force wins the match.

Cardiac muscle, involuntary and reliant on oxygen, pumps blood, while smooth muscle regulates various functions without direct neuronal control. Skeletal muscle enables voluntary movement with specialized fibers. Muscle contractions are powered by ATP and facilitated by the sliding-filament model, with fibers classified as Type I or Type II.
