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 questionnaire. Participants were randomly 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.
