Bilateral contraction in muscles refers to the simultaneous activation and contraction of muscles on both sides of the body. This coordinated action is often essential for maintaining balance, stability, and proper movement during activities such as walking, running, or lifting. For example, when you perform a squat, the muscles in both legs contract together to support the movement. This allows for efficient force generation and enhances overall body control.
Bilateral contraction of the erector spinae group results in extension of the spine, helping to maintain an erect posture and stabilize the vertebral column during activities like standing and lifting.
Anerobic contraction of muscles.

The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
A hereditary disease of the muscles characterized by prolonged contraction of the muscles whenever voluntary motion is attempted, contraction and relaxation being slow and the muscles stiff.
An involuntary muscle contraction is called a spasm.
Muscles are tissues composed of fibers, the contraction of which produces movement in the body.
