abstract
Cardiovascular disease (CVD) is the leading cause of death in the United States. Obesity is a major risk factor contributing to CVD and elicits a negative effect on endothelial function. Participants of this EPSCoR study were recruited and categorized into one of four groups: 1) Lean Active (LA); 2) Lean Sedentary (LS); 3) Overweight Active (OA); and 4) Overweight Sedentary (OS). Baseline blood flow (BBF) and reactive blood flow (RBF), stimulated by a 4-minute occlusion of the brachial artery, were measured using venous occlusion strain-gauge plethysmography – a measure of endothelial function. The specific aim was to determine the effects of habitual physical activity (PA) and body composition on BBF and RBF. BBF was similar between all four groups. The LA group showed significantly greater absolute and relative RBF values when compared to both sedentary groups (p=0.001). The OA and LS groups demonstrated similar RBF values. Regression analysis revealed a significant negative relationship between percent body fat and RBF. When co-varying for percent body fat, the greater RBF in the LA group was maintained. These findings suggest that PA has a more powerful effect on stimulated forearm blood flow than body composition and may provide some cardioprotection in overweight adults. note
