The tension applied to the load when a muscle stretches but is not stimulated is called "passive tension." Passive tension arises from the elastic properties of the muscle and connective tissues when they are elongated. This type of tension does not require active neural stimulation to occur; instead, it is due to the physical response of the muscle fibers and associated tissues to being stretched.

When a muscle is in a passive state, it is compliant and can still bear load without generating additional active force. This characteristic is important in various physiological and biomechanical contexts, including maintaining posture and preventing injury during physical activities. Understanding passive tension can also aid in designing rehabilitation protocols and training regimens that account for the elasticity of muscle tissues.
