FIGURE 7.

(A, B) Arteriovenous plasma BCAA differences and (C–E) forearm (skeletal muscle) BCAA uptake in response to consumption of a liquid test meal before (pre) and after (post) 2 wk of dietary intervention. Data are means ± SEMs. n = 8 for eTRF and n = 6 for CON:CR. Forearm BCAA uptake is expressed relative to lean forearm mass (in kg) determined by DXA. P values displayed in text boxes refer to mixed-design 3-factor ANOVA (intervention group × pre-post trial × sampling time) performed for the entire postprandial period (A–D) and mixed-design 2-factor ANOVA (intervention group × pre-post trial) performed for incremental area under the curve data (E). BCAA, branched-chain amino acids; CON:CR, control/caloric restriction; eTRF, early time-restricted feeding.
