The heterogeneity in reported effects was reduced in higher quality studies , when physical activity was self-directed with some professional guidance and when there was on-going professional support .
Our review suggests that physical activity interventions have a moderate effect on self reported physical activity and cardio-respiratory fitness , but not on achieving a predetermined level of physical activity .
Due to the clinical and statistical heterogeneity of the studies , only limited conclusions can be drawn about the effectiveness of individual components of the interventions .
BACKGROUND Little is known about the effectiveness of strategies to enable people to achieve an increase in their physical activity .
OBJECTIVES To assess the effects of interventions for promoting physical activity in adults aged 16 years and older , not living in an institution .
A Green Prescription Study
Objective : To determine if a written exercise prescription increases physical activity when added to verbal advice . Methods : Forty-nine community-dwelling older adults supplied their geriatricians with baseline data on their exercise levels using a question naire . Participants were r and omly placed in a verbal advice only group or a verbal advice plus written prescription , “ green ” prescription , group . Outcomes were assessed after 6 weeks . Results : Both groups showed a significant increase in time spent in physical activity . However , no significant differences between groups due to the effects of the different advice modalities were found . Conclusions : Geriatricians can effectively promote physical activity among sedentary older adults through goal -oriented physical activity advice
