Primary Outcome Measures:
  • tumor necrosis factor (TNF-alpha) [ Time Frame: change from before (pre) to after (post) 12 weeks of training & after 4 weeks of post-deconditioning ] [ Designated as safety issue: No ]
    TNF-alpha will be measured from whole blood samples stimulated with lipopolysaccharide


Secondary Outcome Measures:
  • Change in mood, including depressive symptomatology and negative affect [ Time Frame: change from before (pre) to after (post) 12 weeks of training & after 4 weeks of post-deconditioning ] [ Designated as safety issue: No ]
  • interleukin 1 (IL-1), IL-6, IL-8, IL-10 [ Time Frame: change from before (pre) to after (post) 12 weeks of training & after 4 weeks of post-deconditioning ] [ Designated as safety issue: No ]
    these cytokines will be measured from whole blood samples stimulated with lipopolysaccharide

  • TLR-4 [ Time Frame: change from before (pre) to after (post) 12 weeks of training & after 4 weeks of post-deconditioning ] [ Designated as safety issue: No ]
    TLR-4 will be measured from blood samples

  • cerebral blood volume (CBV) in the dentate gyrus [ Time Frame: change from before (pre) to after (post) 12 weeks of training ] [ Designated as safety issue: No ]

Detailed Description:

Aerobic exercise - the most widely recommended health behavior - is recognized to reduce the risk of coronary heart disease, so much so that consensus panels routinely include it as part of a cardioprotective regimen for healthy people, but the physiological or mechanistic basis of this protection is uncertain. Understanding the mechanisms has considerable public health significance because it will allow development and testing of targeted interventions to produce comparable cardioprotective effects more directly or in cases where aerobic exercise is not possible. This application proposes to test the hypothesis that aerobic training leads to attenuation of the inflammatory response to LPS stimulation and to examine the role played by exercise-induced increases in vagal activity, improvements in mood, and decreased expression of Toll Receptor 4 (TLR4), the cognate receptor for endotoxin expressed by monocytes.
