There is also a reduction of the satellite cells (responsible of regeneration), loss of excitability (decrease of the receptors), decline of the myosin protein content (reduction of the number of cross-bondings and of the maximum strength previous to the failure), rigidity (elasticity reduction), physical inactivity (affecting type I fibers), loss of mitochondrial content and function, and comorbidities such as cancer, diabetes and type II chronic heart failure (13, 14).
The expression level of HGF mRNA, which is a well-studied activation factor for satellite cells, was significantly increased in the Precon group at 2 and 4 days after damaging ECC (Figure 3(a)).

In brief, increased oxidative stress as a result of redox imbalance during aging leads to increased susceptibility of satellite cells to apoptosis and affects muscle regeneration [6, 8, 29, 30].

Moreover, the study on satellite cells [29] and differentiated muscle cells [30] indicated that LLLI promoted SIRT1 deacetylase activity, probably through increased [NAD.sup.+] level or the enhancement of SIRT1 protein expression.
