T state (tense)

The T state, or tense state, refers to the condition of a muscle when it is relaxed and not actively contracting. In this state, muscles maintain a baseline level of tone, providing stability and readiness for movement. Tension in this context is controlled by the nervous system, which signals muscles to stay slightly contracted so they are prepared for action, but not fully engaged. This state is essential for posture, balance, and coordinated movements, allowing muscles to respond quickly when a contraction is needed. The T state balances the need for both readiness and relaxation in normal muscle function.
