Figure 7. Circulating T cell populations reflect neurocognitive function after long-term physical activity.

Figure 7.

(A) Sedentary baseline (squares; n=12) aMCI subjects with better executive function (i.e. higher numbers = better cognitive function, Trails B) exhibit no trend for either circulating (A) CD4+ T cells or (C) CD8+ T cells. Physical activity (PA) group, including individuals in the stretching/toning (closed circles; n=7) and aerobic exercise training (open circles; n=5) interventions exhibit opposite patterns for T cell subsets in the circulation, with improved executive function associated with more (B) CD4+ T cells and fewer (D) CD8+ T cells in the blood.
