Physical activity and cancer risk. Actual knowledge and possible biological mechanisms

Physical activity and cardiovascular mortality risk: possible protective mechanisms?

INTRODUCTION The biological mechanisms through which increased physical activity or structured exercise training lowers the risk of recurrent cardiac events are incompletely understood. We examined the extent to which modification of primary risk markers explains the association between physical activity and cardiovascular death in participants with diagnosed cardiovascular disease (CVD). MET...

Physical Activity and Gastrointestinal Cancers: Primary and Tertiary Preventive Effects and Possible Biological Mechanisms

Gastrointestinal cancers account for 37% of all cancer deaths worldwide, underlining the need to further investigate modifiable factors for gastrointestinal cancer risk and prognosis. This review summarizes the corresponding evidence for physical activity (PA), including, briefly, possible biological mechanisms. Despite high public health relevance, there is still a scarcity of studies, especia...

Physical activity and cancer prevention--mechanisms.

PURPOSE This paper presents potential mechanisms by which exercise or physical activity may affect cancer development. METHODS Analysis of published and unpublished experimental and epidemiological data from the cancer-activity literature and from other fields of study are compiled to provide a summary of potential mechanisms by which exercise may mediate cancer development. RESULTS Exercis...

Physical activity and cancer prevention: a review of current evidence and biological mechanisms.

OBJECTIVE The main aim of this paper is to review the evidence available from the date of PubMed's inception to May 2011 for a link between cancer and physical activity (PA) in both animal models and humans. METHODS We decided to select studies that comply with the scheme proposed by the American College of Sports Medicine/American Heart Association (ACSM/AHA) that distinguish occupational ph...
