This study examines the effectiveness of Texercise Select, a 12-week lifestyle program to improve physical functioning (as measured by gait speed) and quality of life. Baseline and 12-week follow-up assessments were collected from 220 enrollees who were older (mean = 75 years), predominantly female (85%), White (82%), and experiencing multiple comorbidities (mean = 2.4). Linear mixed-models were fitted for continuous outcome variables and GEE models with logit link function for binary outcome variables. At baseline, over 52% of participants had Timed Up-and-Go (TUG) test times of 12 s or more, which indicates below-normal performance. On average, participants showed significant reductions in TUG test scores at the postintervention (11% reduction, p < .001). Participants also showed significant improvements in general health status (p = .002), unhealthy physical days (p = .032), combined unhealthy physical and mental days (p = .006), and days limited from usual activity (p = .045). Findings suggest that performance indicators can be objectively collected and integrated into evaluation designs of community-based, activity-rich lifestyle programs.
