Overload leads to muscle hypertrophy. In the process, several events occur inside and outside the myofibers, including increased protein synthesis, change in gene expression, fiber-type transition, satellite cell activation, and angiogenesis (Bassel- Duby and Olson 2006; Blaauw et al. 2009). Interestingly, at the early phase of muscle hypertrophy, protein synthesis significantly increases (Baar et al. 2006), and later the transcription of growth-related genes follows (Carson 1997). Satellite cell activation is generally thought to be a critical component for increase in muscle mass; however, it is still a debated issue whether satellite cell incorporation into hypertrophying muscle fibers is required for muscle hypertrophy (O’Connor and Pavlath 2007; McCarthy and Esser 2007).
