Figure 5. Kinetic protein synthesis measurement in non-immobilized gastrocnemius muscles of PAIR-FED, CONTROL and LEU old adult rats.

Muscle protein synthesis at I0 and I8 in the post-absorptive and the post-prandial states for each time is expressed as the absolute synthesis rate (ASR), i.e. the amount of proteins synthesized in mg.day⁻¹ for rat fed the pair-fed (A), CONTROL (B) and LEU (C) diets. LEU, leucine; IM, immobilization period; I0, before immobilization; I8, 8 days of casting; R10 to R40, 10 to 40 days of recovery; PA, post-absorptive state; PP, post-prandial state. * P<0.05, PA vs. PP. Values with different letters are significantly different from each other. Data are means ± SEM.
