Accumulated brisk walking reduces arterial stiffness in overweight adults : evidence from a randomized control trial . Arterial stiffness is a major contributor to the development of atherosclerosis and consequently cardiovascular disease . This study aimed to examine whether 6 months of accumulated ( 3 × 10 minutes , 5 days/week ) brisk walking was sufficient to reduce arterial stiffness in sedentary , overweight individuals . Seventy-seven individuals ( 19 men , 58 women ; age , 30-55 years ) were randomly allocated to one of three groups ; two groups completed 30 minutes of accumulated walking with either monthly or weekly telephone support ; the third group ( control ) performed stretching exercises . The walking groups were combined and telephone support included as a covariate . Anthropometry , blood pressure ( BP ) , blood lipids , pulse wave velocity ( PWV ) , and NOx ( surrogate marker for nitric oxide ) were measured at baseline , post-intervention and 4 months post-intervention . No changes were observed for anthropometry , BP , or lipids . However , at the end of the intervention , there was a decrease in PWV ( P < .001 ) accompanied by an increase in NOx ( P < .001 ) , with changes maintained 4 months post-intervention . A strong negative correlation between PWV and NOx was also observed ( P < .001 ; r = -0.65 ) . A lifestyle approach to meeting current physical activity guidelines results in favorable alterations in arterial function in overweight individuals .
