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 .
Preliminary evaluation of a multicomponent program for nutrition and physical activity change in primary care: PACE+ for adults.
BACKGROUND Patient-centered Assessment and Counseling on Exercise plus nutrition ( PACE+ ) is an intervention based in primary care setting s to help patients change physical activity and dietary behaviors . METHODS One hundred seventy-three adults were assessed before and after a 4-month intervention . All patients completed a computerized assessment and created tailored " action plans " to change one physical activity and one nutrition behavior that they then discussed with their provider . After the visit , subjects were r and omized to one of four extended intervention conditions : control , mail only , infrequent phone and mail , and frequent phone and mail . Self-report of five target behaviors ( moderate and vigorous physical activity stage of change , dietary fat , fruit/vegetable intake , and overeating behaviors ) was collected at baseline and 4 months . Acceptability measures were also taken . RESULTS Participants in all conditions improved on all behaviors over time , supporting the utility of the computer and provider counseling components . The extended intervention did not produce differential results with respect to mode ( phone or mail ) or intensity ( frequent or infrequent ) . However , for each behavior , participants who targeted the behavior to change improved significantly more than those who did not target the behavior . Acceptability of the intervention was high . CONCLUSIONS Primary care-based , interactive health communication to improve physical activity and dietary behavior is feasible and has promising initial results
