Pearson's correlation coefficients (R) between the ratio of the increase in nNOS, eNOS, and MyoD mRNA expression, and the ratio of the increase in MyoD, VEGF-A and FGF2 mRNA expression. Pearson's R was calculated based on total data for three experimental groups in each muscle from young and old mice.
*: Significant correlation between each factor (P < 0.05).
