Contracts that produce movement include concentric, eccentric, and isometric contractions. Concentric contractions occur when a muscle shortens while generating force, such as lifting a weight. Eccentric contractions happen when a muscle lengthens while under tension, like lowering a weight. Isometric contractions involve muscle activation without changing the muscle length, as seen in a plank hold.
When a muscle contracts concentrically, it shortens to produce movement, while the antagonist muscle, which opposes that movement, contracts eccentrically to control the motion. This eccentric contraction allows the antagonist to lengthen under tension, providing stability and preventing injury by absorbing some of the force generated during the concentric contraction. This coordinated action helps maintain balance and control during movements.

The English translation of "otot" is "muscle." It refers to the tissue in the body that contracts to produce movement. Muscles play a vital role in various bodily functions and physical activities.
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.

A pair of muscles works through a mechanism called antagonistic contraction. One muscle, known as the agonist, contracts to produce movement, while its counterpart, the antagonist, relaxes to allow that movement to occur. For example, when bending the elbow, the biceps (agonist) contracts while the triceps (antagonist) relaxes. This coordinated action enables smooth and controlled motion in the body.
Muscles work in antagonistic pairs to move bones. The pairs consist of an agonist (prime mover) that contracts to produce a movement, and an antagonist that relaxes to allow the movement to occur smoothly. This coordinated action helps control the direction and speed of movement.
