Abstract
Background and Aim: Although the cardiovascular risk factors are critical in obese women, it is possible to control related problems using by fiseable exercise training and nutrition strerategies. The aim of this study was to investigate the effects of 8 weeks aerobic exercise training along with green tea consumption on the some cardiovascular risk factors in obese women. Materials and Methods: 46 healthy obese women voluntarily participated in this study and divided randomly into 4 groups including aerobic training (n=13), green tea (n=11), aerobic training+green tea (n=12) and control (n=10) groups. Aerobic training program included aerobic exercises up to 60 minutes at 55%- 65% maximum reserve heart rate, three sessions per week which lasted for 8 weeks. Green tea group brewed 2.5 g green tea in every meal during 8 weeks. Aerobic training+green tea group performed aerobic exercises along with green tea consumption but the control group received no intervention. The blood samples were collected 48 h before and after 8 weeks of protocol in fasting status. The low density lipoprotein (LDL-C), high density lipoprotein (HDL-C), triglyceride (TG) and high sensitive C-reactive protein (hs-CRP) were measured using standard methods. To determine normal distribution of data, we used the Kolmogorov-Smirnovtest; then it is applied the one-way analysis of variance (ANOVA) and Scheffe tests in significant level of p<0.05. Result: There were significant differences (p=0.0001) in hs-CRP variations between groups so that lesser value observed in the aerobic exercise+green tea group than green tea (p=0.001), aerobic training (p=0.03) and control (p=0.0001) groups. Also, it is observed significant differences in LDL-C variations between groups (p=0.009) so that its value had significant reduction in aerobic exercise+green tea (p=0.01) and aerobic exercise (p=0.03) groups than control group. On the other hand, the HDL-C variations was higher in the green tea group than control group (p=0.007), while there were no significantly differences between other groups. Moreover, although all experimental groups showed significant reduction (p=0.0001) in subcutaneous fat percent than control group; there were no significantly differences (p=0.20) in TG between groups. Conclusion: Perform of aerobic exercise along with green tea consumption will induce more improvement in cardiovascular risk factors of obese women because of its antioxidant anti-inflammatory effects of this supplement.
