Izomfeszültség
Izomfeszültség, often translated as muscle tension or muscle tone, refers to the partial contraction of muscles even when they are at rest. This constant state of readiness allows muscles to react quickly to stimuli and maintain posture. It is a normal physiological phenomenon essential for everyday movements and stability. When a muscle is not actively contracting, it still maintains a low level of activity, providing resistance against passive stretching and enabling smooth, controlled motions. This baseline tension is regulated by the nervous system, specifically through the continuous firing of motor neurons. Disruptions in this normal process can lead to either increased muscle tension, known as hypertonia, or decreased muscle tension, known as hypotonia. Hypertonia can manifest as stiffness and spasticity, while hypotonia can result in weakness and reduced muscle strength. Various factors can influence izomfeszültség, including physical activity, stress, and certain medical conditions. Maintaining healthy muscle tone is important for overall physical function and well-being.
