Figure 5. IL-10, VEGF, and PGC1-alpha expression after aerobic exercise. (A) Rg1 supplementation lowers IL-10 mRNA 3 h after exercise (-60%, P < 0.05). Dramatic elevations for VEGF mRNA (B) and PGC1-alpha mRNA (C) occurred 3 h after 1-h cycling exercise (70% V̇O2max). Data are expressed as mean and SEM. * Significant difference against Pre (Baseline), P < 0.05. Abbreviation: PLA, Placebo.
