Effects of personal, social and environmental factors on physical activity behavior among adults

despite the guidelines and the well-recognized benefits of regular physical activity, there is evidence that a large number of people is still reported to be inactive. therefore, the need for interventions that can promote a healthier behavior has increased. as an understanding of the determinants of physical activity behavior by health professionals is an important prerequisite to designing effective interventions, studies on the identification of the determinants of physical activity are warranted. the purpose of this work is to review and update the research on determinants underlying physical activity behaviour in adults and to provide an overview of physical activity patterns among adult populations. the findings highlight the need for an evaluation of the interactive effects of psychosocial, cultural, environmental and public policy influences on physical activity forging a trans-disciplinary paradigm.
