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 .
Predicting older adults' maintenance in exercise participation using an integrated social psychological model.
Little is known about the predictors of maintenance in organized exercise programmes . The aim of this study was to investigate the behavioral predictors of maintenance of exercise participation in older adults , using an integrated social psychological model . To this end , we carried out a prospect i ve cohort study ( n = 1,725 ; age 50 years or older ) involving 10 different types of exercise programmes , with measurements at baseline and after 6 months . Predictors of intention to continue participating and the actual maintenance of  exercise participation in the exercise programme were assessed using a step-wise logistic regression model . Significant odds ratios ( ORs ) predicting the intention to continue with the  exercise programme  were found for female sex , younger age , being married , being a non-smoker , being in paid employment , having a positive attitude towards exercise and having a high self-efficacy at baseline . Significant ORs predicting actual maintenance of exercise participation  were short lapses , absence of lapses , high intention at baseline , high perceived quality of the programme , positive attitude at baseline and few risk situations at baseline . In order to promote maintenance of exercise participation for older adults , effort should be taken to prevent lapses , to help people cope with risk situations for lapses , to improve the attitude towards exercise participation and to improve the quality of the programme
