Association of Physical Activity by Type and Intensity With Digestive System Cancer Risk

Association of Physical Activity by Type and Intensity With Digestive System Cancer Risk Key PointsQuestionsIs physical activity a common protective factor for digestive system cancers, and what is the optimal amount, type, and intensity of physical activity? FindingsIn this prospective cohort study of 43 479 men, physical activity was inversely associated with digestive system cancer risk. Aerobic exercise regardless of intensity was particularly beneficial, reaching a plateau in benefit at approximately 30 metabolic equivalent of task hours per week with 32% risk reduction. MeaningThe optimal exercise regime to prevent digestive system cancers may be to accumulate the equivalent of energy expenditure of 10 hours of walking at an average pace per week primarily through aerobic physical activity of any intensity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA Oncology American Medical Association

Abstract

Key PointsQuestionsIs physical activity a common protective factor for digestive system cancers, and what is the optimal amount, type, and intensity of physical activity? FindingsIn this prospective cohort study of 43 479 men, physical activity was inversely associated with digestive system cancer risk. Aerobic exercise regardless of intensity was particularly beneficial, reaching a plateau in benefit at approximately 30 metabolic equivalent of task hours per week with 32% risk reduction. MeaningThe optimal exercise regime to prevent digestive system cancers may be to accumulate the equivalent of energy expenditure of 10 hours of walking at an average pace per week primarily through aerobic physical activity of any intensity.
