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 .
Evaluation of Individually Tailored Interventions on Exercise Adherence
This study 's purpose was to test the effects of a reversal theory-driven individualized exercise prescription on exercise consistency , weight , percentage body fat , and exercise motivation for a group of faculty , students , and staff at a southwestern university . Participants were r and omly assigned to 5-week education plus monitoring or monitoring-only treatment groups . The hypothesis was that participants in the education plus monitoring group would have more consistent exercisers , higher exercise motivation scores , and greater overall weight loss and decrease in percentage of body fat than would those in the monitoring-only group . Consistent exercisers will score higher than inconsistent exercisers on exercise motivation scores . More participants were exercising at recommended levels in the education plus monitoring group than in the monitoring-only group after the study intervention . Consistent exercisers had significantly higher motivation scores than did inconsistent exercisers . Thus , individualized exercise prescriptions using reversal theory can be beneficial in promoting a consistent exercise program
