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 .
Effectiveness of a lifestyle intervention and a structured exercise intervention in older adults.
OBJECTIVE To evaluate the effects of a lifestyle intervention and a structured exercise intervention on physical activity  in older adults . METHOD Participants were r and omly assigned to a lifestyle intervention ( n=60 ) , including an individualized home-based program supported by phone calls , or to  a structured intervention ( n=60 ) consisting of three weekly supervised sessions . Results were compared with a  control group ( n=66 ) .  Physical activity was measured with self-report question naires , pedometers , and accelerometers before the start ( pretest ) , at the end ( 11 months , posttest ) , and after 23 months ( follow-up ) . The study took place in Belgium from March 2004 until April 2006 . RESULTS At posttest , both intervention groups had significantly increased their total physical activity compared with the control group . At follow-up , the lifestyle group showed significantly larger increases in active transportation and total steps than the control and structured group respectively . There were no longer significant differences between the structured intervention and the control group . CONCLUSIONS The structured and lifestyle interventions were equally effective at the end of the intervention . One year after the intervention the lifestyle group maintained a significant increase in physical activity , which highlights the potential of lifestyle programs in the battle against inactivity in older adults
