There was no evidence for a relationship between intervention effectiveness and mode of delivery or number of intervention contacts ; however , interventions which involved individually tailoring with personalized activity goals or provision of information about local opportunities in the environment may be more effective .
Conclusions Interventions in adults aged 55 to 70 years led to long term improvements in physical activity at 12 months ; however , maintenance beyond this is unclear .
Identified physical activity improvements are likely to have substantial health benefits in reducing the risk of age-related illnesses .
Background Retirement represents a major transitional life stage in middle to older age .
Changes in physical activity typically accompany this transition , which has significant consequences for health and well-being .
The aim of this systematic review was to evaluate the evidence for the effect of interventions to promote physical activity in adults aged 55 to 70 years , focusing on studies that reported long-term effectiveness .
Exploring the Efficacy and Moderators of Two Computer-Tailored Physical Activity Interventions for Older Adults: A Randomized Controlled Trial
Background Important health benefits can be derived when low-cost ( e.g. , computer-tailored ) physical activity interventions for older adults demonstrate sustained effects . Purpose The purpose of the study was to conduct in-depth analysis on the long-term efficacy of two tailored physical activity interventions for older adults . Methods A r and omized controlled trial ( n = 1,971 ) with two computer-tailored interventions  and a no-intervention control group was conducted . The two tailored interventions consisted of three tailored letters , delivered during 4 months . The basic tailored intervention targeted psychosocial determinants alone , while the environmentally tailored intervention additionally targeted environmental determinants , by providing tailored environmental information .  Self-reported behaviors ( i.e. , total physical activity , transport walking and cycling , leisure walking and cycling , and sports ) were measured at baseline and 12 months . Additionally , potential personal , health-related , and psychosocial moderators of the intervention effects were examined . Results The environmentally tailored intervention was effective in changing total physical activity , leisure cycling , and sports compared with the basic intervention and control group . No intervention effects were found for the basic intervention . Moderation analysis revealed that participants with a higher age , lower body mass index , and higher intention were unresponsive to the interventions . Conclusions Providing environmental information is an effective intervention strategy for increasing physical activity behaviors among older adults , especially among certain “ at-risk ” subgroups such as lower educated , overweight , or insufficiently active participants . Moderation analysis was perceived as a promising method for identifying meaningful subgroups that are unaffected by an intervention , which should receive special attention in future interventions
