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 .
Effectiveness of multidisciplinary lifestyle intervention for hypertension: a randomised controlled trial
Lifestyle factors like weight , alcohol consumption , salt intake and physical activity have shown to be important in treating hypertension . There have been made some r and omised trials about the effects of lifestyle interventions , but the numbers of patients have been relatively small and the duration s of follow-ups have been short . No controlled trials assessing the effects of lifestyle intervention in a rehabilitation setting have been reported . In this study , the effects of multidisciplinary lifestyle intervention in rehabilitation centres among middle-aged hypertensive employees were described . A total of 731 hypertensives from 45 worksites were r and omised to lifestyle intervention in a rehabilitation centre or to usual care in an occupational or primary health-care centre for 12 months . St and ard measurements were conducted before the intervention and 1-year later . Blood pressure ( BP ) levels were clearly reduced in the intervention group , while only minor changes were observed in the control group . The net changes between the two groups both for systolic and diastolic BPs were −2.1 mmHg ( 95 % confidence intervals ( CI ) −4.0 to −0.1 ) and −1.5 mmHg ( 95 % CI −2.6 to −0.4 ) , respectively . The net changes were greater among men than women . The multidisciplinary lifestyle intervention in a rehabilitation centre setting produced significant reductions in BP among middle-aged employees with hypertension
