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 .
Improving subjective health at the worksite: a randomized controlled trial of stress management training, physical exercise and an integrated health programme.
Our objective was to evaluate the effect of 12 weeks of stress management training ( SMT ) , physical exercise ( PE ) and an integrated health programme ( IHP ) in a worksite setting on subjective health complaints . To do this , we r and omly split 860 employees into the following groups : control ( n = 344 ) , PE ( n = 189 ) , IHP ( comprising physical exercise and health information ) ( n = 165 ) and SMT ( n = 162 ) . There were no significant effects on subjective health complaints , sick leave or job stress . However , strong and specific positive effects were experienced for the particular goal areas defined for each intervention . The PE group showed improved general health , physical fitness and muscle pain , while the SMT group showed improved stress management . The IHP group showed the strongest effects , affecting most goals set for treatment
