muscle activity
Bodily movement work
Muscle activity refers to the contraction and relaxation of muscle fibers, whether voluntary movements like walking or involuntary processes like heartbeat and digestion.
The term appears frequently in medical and fitness contexts to describe how muscles engage during exercise, physical therapy, or normal bodily function.
The EMG measured muscle activity in her forearm during the grip test.
Reduced muscle activity can indicate injury or neurological conditions, while increased activity often correlates with physical exertion or tension.
