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.

29,902 participants completed the questionnaires and examinations during the 2011–2016 period. Participants who refused or who had missing data from any survey (including demographics, physical activity, physical function, or other health conditions) were excluded. The present study included

Specific to older adults, sedentary behavior (SB) is associated with impaired physical function, frailty, falls, all-cause mortality, depression, and self-efficacy ( Dunlop et

Previous studies have suggested that engaging in physical activity may decrease the loss of physical function caused by aging and OA ( Dunlop

Residents of socioeconomically disadvantaged neighborhoods have significantly poorer physical function than their counterparts residing in more advantaged neighborhoods. 1 Physical function is defined as one’s ability to perform various activities that require physical capacity, ranging from
