Fig. 7.

Fibers positive for embryonic myosin heavy chain (eMHC; A and C) or neonatal myosin heavy chain (nMHC; B and D) relative to total fibers counted (%) evaluated from biopsies obtained pre and post 12 wk of eccentric or concentric training combined with either whey protein or isocaloric carbohydrate supplementation. Since no group or leg interactions were observed data are collapsed for group and leg. Data are presented as individual values and median bars. Overall effects of time (or tendencies) are displayed in top right corner. Images of eMHC (C, green) and nMHC (D, green) positive fibers are obtained from one subject's eccentric posttraining leg containing high amounts of these fibers.
