Trained rats show moderate correlation between glycolytic muscle androgen receptor expression and glycolytic myofiber size, but not whole-body composition. Correlations are presented in panels for: a DXA-measured fat body mass, b DXA-measured lean body mass, c succinate dehydrogenase nonstained (SDH-) glycolytic myofiber minor ellipse in extensor digitorum longus (EDL), and d proportion of SDH- glycolytic myofibers in EDL. Data are presented as subject-matched AR expression (relative density, R.D.) and measured outcome variables, and all correlations are analyzed using Pearson’s correlation. Data are stratified by exercise (red, closed triangles) and sedentary (grey, closed circles) groups, with sex and genotype groups collapsed (a–e). n = 18 per exercise group (collapses n = 4 female–transgene, n = 5 female–wild-type, n = 4 male–transgene, n = 5 male–wild-type), and n = 18 per sedentary group (collapses n = 4 female–transgene, n = 5 female–wild-type, n = 4 male–transgene, n = 5 male–wild-type)
