How is muscle tone defined?

Muscle tone is defined as the amount of tension or resistance in a muscle at rest. This baseline level of muscle contraction is what helps maintain posture and provides the necessary readiness for movement. It is important to note that muscle tone is not indicative of the muscle's strength or flexibility, nor is it related to how quickly a muscle can contract.

When a muscle is toned, it has a certain degree of firmness and readiness for action, which is crucial for balance and motor control. This state of partial contraction also plays a significant role in stabilizing joints and supporting skeletal alignment, contributing to overall functional mobility. Muscle tone can vary from person to person and can be influenced by various factors, including nervous system activity and overall health.
