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 .
Group-mediated activity counseling and traditional exercise therapy programs: Effects on health-related quality of life among older adults in cardiac rehabilitation
Background : Regular physical activity has been consistently related to improvements in health- related quality of life ( HRQL ) in older adults . Nevertheless , systematic investigations of the influence of exercise therapy on older men and women enrolled in cardiac rehabilitation remain sparse . Purpose : The primary purpose of this investigation was to compare the effects of a group-mediated cognitive behavioral physical activity intervention program ( GMCB ) to a traditional cardiac rehabilitation program ( CRP ) with regard to changes in HRQL in a community-dwelling sample of older adults . Methods : This r and omized clinical trial assigned 147 participants who were eligible for inclusion in cardiac rehabilitation to the GMCB or traditional CRP arms . Changes in HRQL at 3 and 12 months were assessed using the Short Form-36 ( SF-36 ) from the Medical Outcomes Study . Results : Mixed-model analyses yielded significant Baseline × Gender × Treatment interactions for the self-reported mental health component and the Vitality subscale of the SF-36 . Decomposition of these interactions revealed that men in both exercise therapy groups and women in the GMCB treatment with low baseline values demonstrated more favorable improvements in the HRQL perceived mental health measures than women in the CRP treatment . Conclusions : Improvements in HRQL among older adults enrolled in cardiac rehabilitation differ as a function of treatment , gender , and initial mental health status . Results are discussed in terms of the implication s for the design of future physical activity interventions among older adults with cardiovascular disease and the measurement of their HRQL
