Fig. 1From: Whey protein sweetened with Stevia rebaudiana Bertoni (Bert.) increases mitochondrial biogenesis markers in the skeletal muscle of resistance-trained ratsExercise adaptations in resistance-trained rats. Body weight during the 8-weeks of the resistance training (a) and the body weight gain after this period (b), n = 9 SC and 10 TC. Food intake during the 8-weeks of the resistance training (c), n = 10. Weight of the skeletal muscles pads (d), white adipose tissues pads (e) and brown adipose tissue pad (f), n = 10 SC and 9 TC. Muscle fiber (g) and retroperitoneal adipocytes (h) diameters, n = 6. Maximum load-carrying capacity at the end of resistance training program (I), n = 10. For the representative images of muscle fibers and adipocytes diameters, see Additional file 1: Figures S1 and S2. SC, sedentary control rats; TC, trained control rats.
