Figure 3.
Whole-body endogenous phenylalanine kinetics. Data are presented as mean±SE. A, Rate of appearance (Ra) of whole-body protein (which is a reflection of protein breakdown). In the oxandrolone group, whole-body protein Ra was significantly (p < .05) lower following AA infusion than during basal period. B, Whole-body muscle protein Ra. C, whole-body non-muscle protein Ra. AA infusion did not affect whole-body muscle Ra (B) or whole-body non-muscle protein Ra in either group (C). *, p < .05, significantly different from basal period.
