Figure 4. Muscle protein synthesis, absolute synthetic rate, fractional growth rate and absolute breakdown rate.

A, muscle protein synthesis (MPS) rates in UT and T legs in Y and O individuals. B, fractional growth rate (FGR). C, absolute synthetic rate (ASR). D, absolute breakdown rate (ABR). Values are means ± SEM. *Significantly different from UT, P < 0.05. T, trained; UT, untrained.
