Effect of Eight Weeks of Aerobic Training and Green Tea Supplementation on Cardiovascular Risk Factors in Inactive Overweight Women

Abstract

Aims: Physical activities, as well as diet, are known as the truest scientific methods to reduce the signs of the cardio-vascular diseases. The aim of this study was to investigate the effects of 8-week aerobic trainings and green tea supplementation on some of the cardio-vascular risk factors in the obese inactive women. Materials & Methods: In the semi-experimental study, 40 obese inactive women, who were residents of Mashhad Township, were studied in 2015. The subjects, selected via purposeful available sampling method, were randomly divided into 4 groups (n=10 per group). The groups were green tea, aerobic training, aerobic training and green tea supplementation, and control groups. 8week training program consisted of three 45-to 60-minute sessions per week. Green tea was consumed by green tea group three times a day after each meal. The composed group underwent both interventions, while control group underwent no intervention. Data was analyzed by SPSS 15 software using correlated T test and one-way ANOVA. Findings: Mean total cholesterol level was significantly changed in green tea, aerobic training, and composed groups in the posttest stage compared to the pretest stage (p<0.05). Mean triglyceride level was significantly changed in green tea and aerobic training groups in the posttest stage compared to the pretest stage (p<0.05). Mean low density lipoprotein was significantly changed in green tea and composed groups in the posttest stage compared to the pretest stage (p<0.05). Mean high-density lipoprotein was significantly changed only in aerobic group in posttest stage compared to the pretest stage (p<0.05). In addition, mean concentration of C-reactive protein was significantly reduced in aerobic training (p=0.01) and composed (p=0.04) groups. Conclusion: 8 weeks aerobic training, green tea consumption, and their composition reduce the cardiovascular risk factors in inactive obese women in a relatively similar manner.

Lipid-Lowering Effects of Concurrent Training and Green Tea Consumption in Overweight Women

“…Contrary to the findings of the present study, however, some studies have shown that training with GT consumption has no interactive effect on improving the lipid profile in obese participants. 26 - 28 However, differences in the results of this study and others may be attributed to are the sex of the study participants as well as variations between the compounds and the dose of GT. Moreover, these inconsistencies could be due to different training patterns.…”

The Effect of Aerobic Exercise Training on Ox-LDL Levels and Some Cardiovascular Risk Factors in Women with Obesity

“…Fathei et el. (17), demonstrated that eight weeks of aerobic training, green tea consumption, and their composition reduce the cardiovascular risk factors in inactive obese women in a relatively similar manner. The research evidence showed the association between Ox-LDL and obesity (18,19), which contradicts the findings of this study.…”

Assessment of Hepatic and Lipid Profiles Following 12 Weeks of Aerobic Exercise in Overweight Postmenopausal Women

“…The studies have reported that regular exercise modulates the daily energy intake, lipid oxidation in the skeletal muscle and mitochondria, hepatocytes, and increases fat metabolism and redistribution in visceral fat tissues resulting in a decrease in free fatty acids (FFA) supply to the liver, a decrease for deposit of fat in the liver, and an increase in fat oxidation of the liver. 35 However, it is possible that 12-week W-WJMIAEP-R intervention has not been able to stimulate fat oxidation in the liver, and this may require more than 12 weeks of W-WJMIAEP-R intervention in overweight PMWs over 50 years old. The results of studies have shown that the aging process decreases daily physical activity level and basal metabolism rate (BMR) in the human, resulting in weight gain.…”

“…As mentioned above, overweight and physical inactivity lead to a decrease in daily energy intake, lipid oxidation in the skeletal muscle and mitochondria, decreased hepatocyte functions, altered fat metabolism, redistribution of fat stores in the body, decreased supply of FFA to the liver, and elevated fat oxidation in the liver. 35 These events are risk factors for liver and CVS damage caused by the aging process among overweight PMWs over 50 years old. In fact, it is likely that these changes are caused by a reduction in estrogen and progesterone levels, physical inactivity, 36 overweight, 37 and accumulation of visceral fat during menopause.…”
