Greater physical activity of an aerobic nature ( categorized by a variety of methods ) was associated with higher functional status ( expressed by a host of outcome measures ) in older age .
For functional independence , moderate ( and high ) levels of physical activity appeared effective in conferring a reduced risk ( odds ratio ~0.5 ) of functional limitations or disability .
Limitation in higher level performance outcomes was reduced ( odds ratio ~0.5 ) with vigorous ( or high ) activity with an apparent dose-response of moderate through to high activity .
Exercise training interventions ( including aerobic and resistance ) of older adults showed improvement in physiological and functional measures , and suggestion of longer-term reduction in incidence of mobility disability .
A relatively high level of physical activity was related to better cognitive function and reduced risk of developing dementia ; however , there were mixed results of the effects of exercise interventions on cognitive function indices .
Conclusions There is a consistency of findings across studies and a range of outcome measures related to functional independence ; regular aerobic activity and short-term exercise programmes confer a reduced risk of functional limitations and disability in older age .
Although a precise characterization of a minimal or effective physical activity dose to maintain functional independence is difficult , it appears moderate to higher levels of activity are effective and there may be a threshold of at least moderate activity for significant outcomes
Background The purpose was to conduct systematic review s of the relationship between physical activity of healthy community-dwelling older ( > 65 years ) adults and outcomes of  functional limitations , disability , or loss of independence .
On a happier note: validation of musical exercise for older persons in long-term care settings.
This paper describes a quasi-experimental study of a musical exercise intervention to improve the physical , cognitive , behavioral status and life satisfaction of older residents in a long-term care facility in the United Kingdom . Twenty long-term care residents from three different units ( n=60 ) were recruited and assigned to one of three groups : a control ( C ) group ( no intervention ) , an occupational therapy ( OT ) group ( comparison group ) and a music exercise group ( intervention group ) . Assessment s of physical and cognitive status were made pre-intervention and repeated at the end of the 10-week exercise program and again 10 weeks after the completion of the program . The results show that both OT and exercise participation is associated with improvement in physical and cognitive function . However , the exercise group showed significant improvement in more areas than the OT group . The functional benefits from OT and exercise were not sustainable after these activities ceased and showed significant decline 10 weeks after the end of the programs
