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 .
Outcomes of an Exercise Program for Older Women Recruited through Primary Care
Objectives : This study reports the social cognitive , health status , and health service use outcomes of an exercise intervention among women over 50 years of age . Methods : A r and om sample of patients was drawn from two primary care centers that serve a predominantly low-income and African American population . After provider screen , 412 women were eligible and invited to participate in the study . Of these , 123 participated and 1-year follow-up data are available for 72 participants . Results : Participants were more likely to be African American and had a higher average body weight than non participants . Perceived health was the only variable that differed by adherence group at baseline . At 1 year , differences were apparent for body weight , body mass index , hip and waist circumference , triceps skinfold , and exercise self-esteem . The no-adherence group got worse , whereas the moderate adherence group improved . Discussion : These data suggest that even suboptimal adherence to moderate-intensity exercise can yield health benefits
