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 .
Evaluation of a culturally appropriate intervention to increase physical activity.
OBJECTIVE To evaluate a culturally appropriate intervention to increase activity in overweight Mexican American women . METHODS Participants were r and omly assigned to a physical activity program or wait-list control . RESULTS Treated participants were not more active than controls at 6 or 12 months . In addition , we found no significant differences in the proportion of individuals who met an objective criterion for physical activity from baseline to 6 months in the treatment or control groups . CONCLUSION The intervention did not increase physical activity in this population . Differences in baseline activity and contamination of the control group may partially account for the outcome
