36. Joint Association of Walking and Vigorous Exercise with the Age-Adjusted Relative Risk of Cardiovascular Disease Manson, J. et al. N Engl J Med 2002;347:716-725

37. Multivariate Relative Risk of Cardiovascular Disease and Relative Risk Adjusted for Age and Walking Time, According to Walking Pace Manson, J. et al. N Engl J Med 2002;347:716-725

38. Conclusions These prospective data indicate that both walking and vigorous exercise are associated with substantial reductions in the incidence of cardiovascular events among postmenopausal women, irrespective of race or ethnic group, age, and body-mass index Prolonged sitting predicts increased cardiovascular risk
