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 .
Minimal-contact physical activity interventions in women: a pilot study.
OBJECTIVE To examine the impact of 3 minimal-contact lifestyle interventions on physical activity in women . METHODS Fifty female volunteers were r and omly assigned to one of 3 lifestyle physical activity interventions for 8 weeks . Subjects wore an accelerometer for a week at baseline and postintervention to objective ly monitor their physical activity . RESULTS Participants significantly increased their physical activity from baseline to postintervention ; however , there was no significant difference in physical activity among the 3 intervention groups . CONCLUSIONS Results of this pilot study support the use of minimal-contact lifestyle interventions to promote physical activity in women
