Physiological decrease in estrogen levels and accumulation of visceral fat and being overweight, increase the risk of cardiovascular disorders in the menopausal years. The aim of this study was to determine the effects of aerobic exercising on plasma nitric oxide level and vessel endothelium function in postmenopausal women. Methods: In this semi-experimental study, twenty-three healthy postmenopausal women with the average of age: 54.4±5.56 years were randomly divided into two exercise group (n= 13) and control (n=10) group. The exercise group performed aerobic exercise for eight weeks, three sessions per week with 50-70% of maximum heart rate reserve. The duration of each training session was increased from 30 to 45 minutes gradually. During this period, the control group did not participate in any regular exercise program. Before and after aerobic training program, anthropometric measurements, VO2 max, nitric oxide concentrations and Flow Mediated Dilation (FMD) of all subjects were measured. Data were analyzed with paired t-student test at a significance level of p SP - 78 EP - 88 AU - Farahati, Samaneh AU - Atarzadeh Hosseini, Seyed Reza AU - Bijeh, Nahid AU - Mahjoob, Omid AD - Ferdowsi University of Mashhad KW - Aerobic exercising KW - Endothelium function KW - FMD index KW - Nitric oxide KW - Postmenopausal women UR - http://rjms.iums.ac.ir/article-1-2928-en.html ER -
