Supervised exercise is beneficial for peripheral artery disease (PAD) patients limited by intermittent claudication (IC). However, supervised exercise for PAD remains widely underutilized. Mobile health (mHealth) provides an intermediate solution between supervised and independent home-based exercise. The purpose of this study was to determine the effects on functional capacity and physical activity patterns of a 12-week mHealth program in PAD patients with IC. Twenty patients were randomized in...

Abstract Background Site-based cardiac rehabilitation (CR) provides supervised exercise, education and motivation for patients. Graduates of CR have improved exercise tolerance. However, when participation in CR ceases, adherence to regular physical activity often declines, consequently leading to worsening risk factors and clinical events. Therefore, the purpose of this pilot study was to evaluate if a mHealth program could sustain the fitness and physical activity levels gained during CR. Meth...

Introduction: STRRIDE Reunion evaluated longitudinal changes in cardiometabolic health 10 years after completion of STRRIDE (Studies Targeting Risk Reduction Interventions through Defined Exercise). Subjects originally were randomized to one of four eight-month interventions: inactive control (IC); low amount moderate, intensity exercise (LAMI); low amount, vigorous intensity (LAVI); high amount, vigorous intensity (HAVI). Methods: Of 153 Duke STRRIDE graduates, 28 were lost to followup; 21 decl...

AB Introduction/Purpose: The goal of this program was to determine the feasibility of a novel noninvasive, highly miniaturized optomechanical earbud sensor for accurately estimating total energy expenditure (TEE) and maximum oxygen consumption (V[spacing dot above]O2max). The optomechanical sensor module, small enough to fit inside commercial audio earbuds, was previously developed to provide a seamless way to measure blood flow information during daily life activities. The sensor module was con...

Abstract Aims To determine if type 2 diabetes mellitus (T2D) differentiates endothelial function and plasma nitrite response (a marker of nitric oxide bioavailability) during exercise in peripheral arterial disease (PAD) subjects prior to and following 3 months supervised exercise training (SET). Methods In subjects with T2D + PAD (n = 13) and PAD-only (n = 14), endothelial function was measured using brachial artery flow-mediated dilation. On a separate day, venous blood draws were performed at...
