Exercise interventions have small clinical benefits on  PA  levels in community-dwelling older adults , with a decline in the observed improvement after six months of the intervention cessation
Exercise is a form of physical activity ( PA ) .
PA is an important marker of health and quality of life in older adults .
The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure , and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65 + year-old adults .
Long-term follow-up of physical activity behavior in older adults.
OBJECTIVE To examine the contribution of social-cognitive factors ( self-efficacy and affect ) in predicting long-term physical activity in a sample of older adults ( N=174 ) . DESIGN A prospect i ve design assessed physical activity and psychosocial variables at 2 and 5 years following a 6-month r and omized , controlled exercise trial . MAIN OUTCOME MEASURES The primary outcome variable was self-reported physical activity , with previous behavior , self-efficacy , and affect assessed as determinants of physical activity . RESULTS Covariance modeling analyses indicated that physical activity at Year 2 was the strongest predictor of physical activity at 5-year follow-up . Both self-efficacy and affect at Year 2 were also associated with physical activity at Year 5 , as was original treatment condition . Variables accounted for 35 % of the variance in Year 5 activity . CONCLUSION Older adults with higher levels of physical activity , more positive affect , and higher self-efficacy at Year 2 were more likely to continue to be active at Year 5 . This study is one of the longest follow-ups of exercise behavior in older adults and has implication s for structuring environments to maximize the maintenance of physical activity
