Skeletal muscle tissue contains a massive taurine (TAU) in millimolar concentrations. Several studies mentioned the importance of TAU in normal skeletal muscle function. It has been found that this amino acid plays a wide range of functions, ranging from osmoregulatory properties to the regulation of cytoplasmic Ca2+ homeostasis. Recent findings mentioned that TAU deficiency in the skeletal muscle leads to decreased exercise capacity, severe weakness, and muscle waste. On the other hand, it has been repeatedly shown that TAU supplementation could increase skeletal muscle performance in many disorders. These data mention the essential role of TAU in the skeletal muscle. Interestingly, it has been found that the effect of TAU on cellular mitochondria is an important feature of this amino acid in skeletal muscles. The current chapter highlights the physiological roles of TAU in muscle and its importance in the pathophysiology of skeletal muscle disorders. Then, the essential role of TAU in cellular mitochondria and its importance in muscle function is described. And the relevance of this amino acid in managing skeletal muscle pathologies is discussed.

Keywords: Amino acid, ATP, Bioenergetics, Cell death, Exercise, Muscle waste, Oxidative stress.
