Asymmetric dimethylarginine (ADMA), myeloperoxidase (MPO) and paraoxonase 1 (PON1) are directly involved in the pathogenesis of atherosclerosis by modulation of oxidative stress and/or NO bioavailability. We aimed to assess whether endurance exercise which is known to be cardioprotective could beneficially affect these novel risk markers. Thirty-two subjects (31–68 yrs, 56% males) with elevated cardiovascular risk including ten patients with coronary artery disease volunteered for a supervised 12-week endurance training (196 ± 15 min/week).Their fitness evaluated by 2 km test runs improved significantly after training (pre: 17.3±0.8 vs. post: 15.7±0.9min, p<0.001). ADMA (pre: 0.94±0.03 vs. post: 0.75±0.04 μmol l⁻¹) and MPO (pre:296.8±22.2 vs.post:185.7±19.5 ng ml⁻¹) serum levels decreased significantly by 17.6±4.6% and 28.5±7.5%, respectively, after training (both p<0.001).Their down-regulation …
