Changes in skeletal muscle androgen receptor protein content are driven by sex differences and chronic aerobic exercise in tibialis anterior. Quantification of western blot analysis of a androgen receptor (AR) from tibialis anterior (TA) muscles, and b the representative immunoblots between males and females with their respective grouping by exercise and HSAAR Tg genotype. Indicated groups: males (yellow), females (green), sedentary (grey), aerobic exercise (red), wild-type (wt) (blank fill), and HSAAR transgenic (Tg) (hatch fill). Data expressed in relative density (R.D.) and presented as means ± s.e.m. Data analyzed using three-way ANOVA with post hoc Tukey HSD for multiple comparisons. a n = 5 per sex–genotype–exercise group
