Quantitative measurements of mitochondrial and cellular structure parameters from n=5 mice in each of the 4 groups of skeletal muscle from young and old, male and female mice. 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).
