The abundance of protein in skeletal muscle fibers is determined by a balance between the rates of protein synthesis and degradation. When the rate of protein degradation exceeds the rate of synthesis, there is a net loss of muscle protein and atrophy occurs. Conversely, when the rate of protein synthesis exceeds the rate of degradation, muscle growth (hypertrophy) occurs.
