Figure 3. Overall amyloid burden increased between sedentary baseline and after 6–12 month of physical activity.

Figure 3.

Standardized uptake value ratio (SUVR) for PET imaging of 18F-florbetapir (amyloid burden) demonstrated a significant increase in Aβ load for (A) total brain, (B) hippocampus, and (C) precuneous cortices between sedentary baseline (squares; n=41) and physical activity (PA) groups, including individuals in the ST (closed circles; n=5) and aerobic exercise training (open circle; n=7) interventions. There were also trends for increased Aβ in the (D) orbital frontal and (E) posterior cingulate cortices. *p<0.05 vs Baseline.
