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 Randomized Control Trial of New Tailored Walking Campaigns in an Employee Sample
Public health groups use mass media communications to address the problem of sedentary behaviour . However , these campaigns are poorly evaluated and lack tailoring . Campaigns and question naires were developed based on existing theoreti cal , cross - sectional , and qualitative data regarding how to promote walking with people who are not regularly active . Subjects were volunteer white - collar employees ( n = 181 ) r and omly allocated by quota to the campaigns , or control , for one week . One - hundred - thirty - eight subjects ( 76 . 2 % ) completed pre - and postcampaign ques tionnaires . T his study successfully ( 1 ) developed four new tailored campaigns to promote walking according to a formalized process that health promoters can adapt and refine , ( 2 ) developed a complimentary measure of outcomes , and ( 3 ) compared the new campaigns with the English Health Education Authority ( HEA ) '' Active for L ife '' campaign ( control )
