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 .
A brief intervention to increase physical activity in sedentary working women.
The purpose of this study was to determine whether a brief , tailored counselling intervention is effective for increasing physical activity in sedentary women when delivered in the workplace . This prospect i ve r and omized trial used a brief intervention based on the Transtheoretical Model . The intervention group received health screening , a brief intervention , and , 2 weeks later , a booster telephone call from a nurse practitioner . The intervention was tailored to each woman 's reported exercise behaviour . The 134 women r and omized to the intervention were compared with 153 women in a control group who received health counselling not tailored to their exercise behaviour and no telephone call . Six weeks later , the intervention group , when compared to baseline , had significantly improved their physical activity , increasing their amount of weekend physical activity as well as minutes walked for exercise , on err and s , total walking , and total daily blocks walked . When compared to controls , they showed significantly greater gains . This test of a brief , tailored strategy provides a critical contribution to the search for efficient , effective ways for nurses to deliver workplace health promotion interventions
