Background Substantial heterogeneity exists in the cardiorespiratory fitness (CRF) change in response to exercise training, and its long‐term prognostic implication is not well understood. We evalu...

ABSTRACT Ranolazine reduces angina frequency and increases exercise capacity. We hypothesized that exercise training with ranolazine would allow subjects to train at greater intensities, resulting in greater improvements in exercise capacity, physical activity and health related quality of life (HRQOL). In a pilot study, subjects with chronic stable angina pectoris were randomized to ranolazine (n=13) or placebo (n=16). Following a two-wk drug titration period, subjects participated in a twelve-...

Background: STRRIDE (Studies Targeting Risk Reduction Interventions through Defined Exercise) was an eight-month exercise study conducted from 1998-2003. Subjects were randomized to control or one of three exercise groups differing in intensity and amount. To determine if there were legacy effects, we invited 161 individuals who completed the intervention phase to return for a 10-year Reunion study. Methods: Subjects completed medical history and physical activity questionnaires. Height, body we...

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...
