The Effect of 8 TRX on Myeloperoxidase and Total Antioxidant Capacity as Indicators of Vascular Endothelial Function in Obese Women

Introduction: Vascular endothelial dysfunction is one of the consequences of obesity or increased body fat mass. This study aimed to determining the effect of TRX training on myeloperoxidase (MPO) and total antioxidant capacity (TAC) as markers of vascular endothelial function in inactive obese women. Methods: 28 inactive middle-aged obese women aged 42±3 years of old (30 ≤ BMI ≤ 36) were randomly divided into of TRX (8 weeks, 3days/weekly, n= 14) and control (no training, n = 14) groups. Fasting levels of TAC and MPO activity and anthropometric indices were measured before and 48 hours after lasting exercise session of groups. Independent and paired t -test use to compare inter and intra-group change of variables (P 0.05). Results: No significant difference was found in TAC (P= 0.356) and MPO (P= 0.268) between groups at baseline (P 0.05). TRX led to a significant increase in TAC activity compared (P= 0.004) but MPO remained no change by TRX (P= 0.459). None of these variables were changed in the control group (P 0.05). Conclusion: Emphasizing the increase in TAC, it is concluded that TRX training are associated with improved vascular endothelial function in inactive obese women.
