Figure 5.

A)There were no differences in DNA %F between CHO or PRO nutrition with aerobic training. B) DNA %F was lower in the younger sedentary group (Yg-SED) than in the older exercise group (Older-EX). Low enrichment of Yg-SED resulted in a DNA synthesis rate that did not differ from 0. Data are expressed as percentage new per week because the Yg-SED group was labeled for 4 wk and the Older-EX group for 6 wk. C) MPS and DNA %F were correlated over 6 wk of aerobic training but not for the Yg-SED (not shown). *P = 0.013.
