SNS overactivity increases CV risk by multiple mechanisms, including vascular stiffness. We tested the hypothesis that aerobic exercise training would reduce resting SNS activity and vascular stiffness in patients with CKD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>\n                      In this randomized controlled trial, sedentary older adults with CKD underwent 12 weeks of exercise (cycling,\n                      <jats:italic>n<\/jats:italic>\n                      = 32) or stretching (an active control group,\n                      <jats:italic>n<\/jats:italic>\n                      = 26). Exercise and stretching interventions were performed 20\u201345 minutes\/session at 3 days\/week and were matched for duration. Primary endpoints include resting muscle sympathetic nerve activity (MSNA) via microneurography, arterial stiffness by central pulse wave velocity (PWV), and aortic wave reflection by augmentation index (AIx).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      There was a significant group\n                      <jats:italic>\u00d7<\/jats:italic>\n                      time interaction in MSNA and AIx with no change in the exercise group but with an increase in the stretching group after 12 weeks.
