Muscle fiber myosin heavy chains in different experimental groups. (a) Sections of gastrocnemius muscle immunolabeled for MyHC I fibers (blue), MyHC IIa (green), MyHC IIx (black), and MyHC IIb (red). (b) The effect of resistance training on MyHC distribution (measured with MyoView). (c) The effect of resistance training on myofiber CSA in different fiber types (measured with MyoView). Image analysis was performed using MyoView software7. Scale bar = 50 µm. **p < 0.001.
