Impact of Self-Preference Community Fitness Interventions in High-Risk African Americans.

African Americans have a high prevalence of obesity and physical inactivity, but few interventions have been successful in the long term. We describe a 1-year intervention program to increase physical activity and reduce cardiometabolic risk. Interventions incorporated the premise that self-selection into flexible venues and varying exercise modalities would result in improvement in fitness and risk factors. Results of this single-group pretest/posttest observational study show 1-year overall group reductions in body weight and body mass index and cardiometabolic factors including high-sensitivity C-reactive protein, and increases in dual-energy x-ray absorptiometry-derived absolute and percent lean mass and lean-fat ratio, and decreased fat mass.
