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 .
The impact of physical fitness and health-age appraisal upon exercise intentions and behavior
This study investigated the relative and combined effectiveness of the Canadian Home Fitness Test ( CHFT ) and Health Hazard Appraisal ( HHA ) to modify ( 1 ) intention to exercise with and without knowledge of the results and ( 2 ) intention and behavior to exercise over 3 months . The 200 subjects were r and omly attributed to groups , either ( 1 ) physical-fitness evaluation ( PF ) , ( 2 ) appraised health age ( HA ) , ( 3 ) physical-fitness evaluation and health-hazard appraisal ( PF-HA ) , or ( 4 ) control ( C ) , The immediate impact on the intention to exercise of passing one and /or the other tests , without knowledge of the results , was not significant . With knowledge of the results , the intentions of the PF and PF-HA groups differed from those of the C group . This effect disappeared after 3 months . There was no significant impact on exercise behavior over 3 months . The results indicated a short-term motivational effect from being informed of CHFT results . Maintaining this effect might require intervention on a long-term basis
