Quantitative measurements of mitochondrial and cellular structure parameters from n=3 mice in each of the 4 groups of skeletal muscle. The data is grouped by sex (Male and Female) and age (Young and Old). Data are reported as mean ± SD and reporting changes that are associated with aging. Statistical significance was assessed using an ordinary two-way ANOVA with biological replicates, with Bonferroni correction for multiple comparisons. Significance was determined at p < 0.05, (* significantly different for males, # significantly different for females, *# significantly different for both groups).
