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 .
An implementation study of two evidence-based exercise and health education programmes for older adults with osteoarthritis of the knee and hip.
Implementation studies are recommended to assess the feasibility and effectiveness in real-life of programmes which have been tested in r and omized controlled trials ( RCTs ) . We report on an implementation study of two evidence -based exercise and health education programmes for older adults with osteoarthritis ( OA ) of the knee or hip . Three types of primary health-care providers ( n = 18 ) delivered the OA Knee programme ( n = 20 ) and the OA Hip programme ( n = 20 ) , supported by programme manuals and implementation guidelines , in four regions . The outcome measures were pain and mobility . The Knee programme had OA knowledge and self-efficacy as additional outcome measures . Differences in outcome measures and background variables of participants were assessed between the RCTs and the implementation study . Positive effects ( P < 0.05 ) were found for OA knowledge , pain and self-efficacy in the Knee programme ( n = 157 ) , and for pain in the Hip programme ( n = 132 ) . No effect was found for mobility . Effect sizes of the RCTs and the present study were comparable . Background variables did not explain the variance in the outcome measures . The outcomes of the previous RCTs and the implementation study were comparable , and indicated the ecological validity of the two programmes . The implication s for nationwide dissemination and implementation in The Netherl and s are discussed
