Exercise Training in “at Risk” Black and White Women: A Comparative Cohort Analyses

ABSTRACTPurposeFew data are available regarding the impact of exercise interventions in black women at risk for cardiovascular disease (CVD).MethodsWomen ≥18 years without known CVD with ≥1 coronary risk factor were enrolled in a community-based exercise program ≥3 days per/week for ≥30 min/session for 6 months. Exercise training intensity ~50[FIGURE DASH]80% of functional capacity, using heart rate (HR) and/or rating of perceived exertion (RPE) as the primary intensity modulators. Pre-versus post conditioning quality of life (QOL) assessments (depression and level of daytime sleepiness), dietary fat intake, Duke Activity Status Index (DASI score), changes in cardiovascular efficiency (systolic/diastolic blood pressure [SBP/DBP], HR, RPE during a standardized submaximal workload), and anthropometric measures, including body weight, body mass index (BMI), and waist circumference, were evaluated.ResultsOf 556 volunteers, 143 were excluded, leaving 413 women (222 white, 191 black; mean ± SD age = 61 ± 9) who met compliance criteria. Both groups demonstrated significant (P
