muscle function
How tissues move
Muscle function refers to what muscles do—contract to produce movement, maintain posture, and generate force.
In physiology and fitness contexts, it describes how well muscles perform their work: The injury impaired muscle function in his left leg.
Good muscle function involves strength, coordination, and the ability to respond to neural signals.
