Fig. 4. Slow- and fast-twitch muscle fibers adapt differentially to exercise training.

Fig. 4

a Diagram displaying proteins that are commonly and exclusively expressed in slow- and fast-twitch muscle fibers + the number of exercise training-regulated proteins in the exclusive population. b Volcano plot comparing fold change (POST vs. PRE) between slow- and fast-twitch muscle fibers. Differently regulated proteins (significance score ≤0.05; paired linear model with Xiao correction72) are marked in blue (change in fast > slow-twitch fibers) and red (change in slow > fast-twitch fibers). c Scatter plot comparing differences in the log2-changes (POST vs. PRE) between slow- and fast-twitch fibers. The graph includes 131 fiber-type-specific (interaction) significant proteins with examples of few protein categories. d Overlap of exercise training-regulated proteins between whole-muscle lysate and slow-twitch muscle fibers. e Overlap of exercise training-regulated proteins between whole-muscle lysate and fast-twitch muscle fibers.
