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 .
Cost-effectiveness of lifestyle and structured exercise interventions in sedentary adults: results of project ACTIVE.
BACKGROUND Project ACTIVE was a r and omized clinical trial comparing two physical activity interventions , lifestyle and traditional structured exercise . The two interventions were evaluated and compared in terms of cost effectiveness and ability to enhance physical activity among sedentary adults . DESIGN This was a r and omized clinical trial . SETTING / PARTICIPANTS The study included 235 sedentary but healthy community-dwelling adults . INTERVENTION A center-based lifestyle intervention that consisted of behavioral skills training was compared to a structured exercise intervention that included supervised , center-based exercise . MAIN OUTCOME MEASURES The main outcome measures of interest included cost , cardiorespiratory fitness , and physical activity . RESULTS Both interventions were effective in increasing physical activity and fitness . At 6 months , the costs of the lifestyle and structured interventions were , respectively , $ 46.53 and $ 190.24 per participant per month . At 24 months these costs were $ 17.15 and $ 49.31 per participant per month . At both 6 months and 24 months , the lifestyle intervention was more cost-effective than the structured intervention for most outcomes measures . CONCLUSIONS A behaviorally-based lifestyle intervention approach in which participants are taught behavioral skills to increase their physical activity by integrating moderate-intensity physical activity into their daily lives is more cost-effective than a structured exercise program in improving physical activity and cardiorespiratory health . This study represents one of the first attempts to compare the efficiency of intervention alternatives for improving physical activity among healthy , sedentary adults
