This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. SIR-Prospective studies suggest that bone loss accelerates with advancing age, leading to markedly decreased bone mineral density (BMD). Because physical activity provides the mechanical stimulus for bone health, low BMD in old age may be due, in part, to disuse atrophy. Some randomized controlled trials (RCT) have found that exercise increases BMD in older adults, but a limitation is that older, physically frail individuals were not included. The aim of this study was to evaluate the effects of a multi-component exercise programme, compared with low intensity home exercise, on BMD in older frail individua
