Abstract
The purpose of the study was to compare the effects of three different types of groupbased exercise programs resistance training agility training and general stretching on back pain and healthrelated quality of life in older aged 75–85 years communitydwelling women with low bone mass ie osteopenia or osteoporosis The design was a 25week randomized controlled trial Participating were 98 communitydwelling women with low bone mass between the ages of 75 to 85 years old We assessed back pain and its related disability and healthrelated quality of life All three types of groupbased exercise programs significantly reduced back pain and its related disabilities but only resistance and agility training significantly improved healthrelated quality of life in communitydwelling older women with low bone mass Baseline physical activity level and class attendance were significant predictors of change in healthrelated quality of life Change in back pain and its related disabilities after 25 weeks of exercise intervention was significantly correlated with change in healthrelated quality of life and changes in the domains of pain and physical function Resistance and agility training significantly enhanced healthrelated quality of life and may have done so by increasing social interactions and support enhancing selfefficacy of physical abilities and modifying the experience of back pain These data provide valuable insight into the specifics of exercise prescription for older women with low bone mass Future studies may wish to use individualized quality of life measures to further delineate the effects of different types of exercise on quality of life in older adults with low bone massThe Vancouver Foundation BCMSF and the BC Women’s Hospital Osteoporosis Program supported this project The South Slope YMCA was a partner of this research project Drs Khan and Eng are Canadian Institutes of Health Research Institute of Musculoskeletal Health and Arthritis New Investigators Drs McKay and Eng are Michael Smith Foundation for Health Research Career Scholars Dr LiuAmbrose is a Michael Smith Foundation for Health Research Post Doctoral Fellow and a Canadian Institutes of Health Research ICE Postdoctoral Fellow
