Skeletal muscle fatigue is a common symptom in various diseases, works and exercises. These were generally induced by neuron, metabolic conditions, overused muscle, and stress. But, there have been few principles about it. Many researchers have reported that acupuncture therapy has been useful to skeletal muscle fatigue on various diseases and conditions. However, it has never been shown why acupuncture therapy has the effect on skeletal muscle fatigue. The deficiency of carnitine induces fatigue, weakness, and disorder of skeletal muscle. It has showed that acupuncture induces the increase of carnitine in skeletal muscle. These findings demonstrated that acupuncture on skeletal muscle fatigue could increase carnitine as a possible affection mechanism.
