Due to lack of high quality studies and often only one manuscript reporting on a particular determinant , we concluded " insufficient evidence " for most associations between determinants and physical activity or exercise .
Background The health benefits of regular physical activity and exercise have been widely acknowledged .
Unfortunately , a decline in physical activity is observed in older adults .
Knowledge of the determinants of physical activity ( unstructured activity incorporated in daily life ) and exercise ( structured , planned and repetitive activities ) is needed to effectively promote an active lifestyle .
Our aim was to systematic ally review determinants of physical activity and exercise participation among healthy older adults , considering the method ological quality of the included studies .
Predictors of adherence to a structured exercise program for older women.
This study examined whether psychological , physiological , and health and lifestyle measures were associated with adherence to a structured exercise program for older women . Women aged " 60 to 85 years ( N = 102 ) , " r and omly recruited from the community , were assessed on these measures before and after a 12-month exercise trial .  Sixty-nine women completed the trial , and 54 continued participation after the trial for at least 6 months . Adherence was examined at various stages during the trial . Multiple regression analysis revealed that reduced muscle strength , slow reaction time , and psychoactive drug use explained most of the variance in adherence during the trial . In contrast , muscle strength , reasoning ability , depression , and self-reported improvement in strength best predicted continued participation after the trial . The findings have implication s for community-based exercise programs and research trials
