 Obesity is one of the greatest health challenges in the world and can lead to kidney disease. The aim of this study was to investigate the effect of aerobic exercise with and without Bunium persicum (Boiss.) consumption on kidney function and the number of trace elements in the blood sample in obese menopausal women.

In this experimental study, 29 obese menopausal women were randomly divided into 3 groups: exercise, supplement, and exercise+supplement with the mean body mass index of 28.3±3.2, 30.4±4.14, and 31.67±4.93 kg/m2, respectively. Eight weeks of exercise was performed in three 45-min sessions per week at 65-75% of the maximum heart rate. The supplement group received two meals of B. persicum for 8 weeks. Before and after the intervention, creatinine, urea, uric acid, iron, zinc, sodium, and magnesium were measured. Data were analyzed by SPSS at the significance level of P≤0.05.

 The results showed that none of the renal function factors in the groups changed significantly. Intra-group changes in zinc significantly increased in the exercise and exercise + supplementation groups (P=0.041 and P=0.010, respectively). Intra-group changes in iron showed a significant decrease and increase in the exercise and supplement groups, respectively (P=0.001 and P=0.001, respectively). The inter-group variation of the iron was also significant (P=0.001).

 Eight weeks of aerobic exercises in water alone and in combination with B. persicum consumption did not affect renal function in obese and menopausal women, while aerobic exercise in water and B. persicum consumption alone led to some changes in trace elements.

Cardiovascular disease, especially coronary heart disease, is one of the leading causes of death in women. This study aimed to evaluate the effect of eight weeks of aerobic exercise in the water with and without consumption of green tea on some blood coagulation factors in inactive postmenopausal women.

The present study is quasi-experimental. 27 obese and inactive postmenopausal women were randomly divided into three groups: exercise group (9 subjects with a mean weight of 68.93±9.1 kg), supplement group (8 subjects with a mean weight of 84.9±17.5 kg) and exercise+supplement group (10 individuals with mean weight of 73.73±10.1 kg). The aerobic exercise program was performed for 8 weeks, 3 sessions per week, and each session for 45-60 minutes with an intensity of 55-75% of maximum heart rate. The supplement group received 200 ml of green tea 3 times daily for 8 weeks. Before and after the training and supplementation protocol, blood samples were collected and changes in plasma fibrinogen levels, platelet count, PT, and PTT were measured. For data analysis, SPSS software version 16 was used at a significance level of p<0.05.

Based on the research findings, changes in PT variables and platelet count were not significant in any of the three groups (p<0.05). Fibrinogen increased in all three groups, which was significant only in the green tea group. PTT decreased in all three groups, which was significant in the green tea group.

Consumption of green tea in the present study increases blood coagulation. Given the importance of blood homeostasis and the adverse effects of disturbing the balance of coagulation and fibrinolysis systems, it seems that any supplementation should be analyzed in terms of its effect on hemostatic balance and the activity of its subsystems.

The important factors in the development of chronic diseases are obesity and overweight. The purpose of this study was to investigate the effect of eight weeks aerobic training on interleukin- 6, insulin resistance and glucose in overweight young girls. Twenty-one girls with an age range of 20-30 years were selected voluntarily and randomly divided into experimental (n = 11) and control (n = 10) groups. The aerobic exercise program lasted for 8 weeks, with a frequency of 3 sessions per week, with training sessions starting from 30 minutes in the first session and 50 minutes in the final session, and the intensity of 60-70% of the heart rate reserve. The blood sample was taken before beginning the main study program. The independent sample t-test, paired sample t- test and the Kolmogorov–Smirnov test were used to compare the pre-test and post-test information between the groups. Eight weeks of aerobic exercise had no significant effect on body mass index (p=0.43), fat percent (p=0.72), waist to hip rate (p=0.85), interleukin- 6 (p=0.86), insulin resistance (p=0.59) and glucose (p=0.78) nevertheless significantly reduced the weight (p=0.004). It appears that eight-week aerobic exercise program could be beneficial for weight loss, but it did not affect glucose concentration, insulin resistance, interleukin- 6 serum, fat percentage, waist to hip ratio and BMI.

Menstrual is an inevitable reality and a part of life for millions of young women around the world. The aim of this study was to evaluate the effects of aerobic exercise on serum level beta - endorphin and pain perception of dysmenorrhea in sedentary adolescent girls. This quasi-experimental study was conducted on 22 subjects with moderate to severe dysmenorrheal and were in age range of 14 to 17 years. They were randomly assigned to a control group (n=10) and experimental (n=12) one. Aerobic exercise program included an aerobic activity with 60-75% of maximum heart rate for 24 sessions (three sessions per week, each session lasting 45-60 min). Before and after the exercise serum level of beta-endorphin was measured. In order to investigate differences within and between groups, Dependent Student t-test and independent student t-test were used. Our findings showed that exercise intervention significantly increased serum levels of beta - endorphin and decreased pain perception index. The results indicated that aerobic exercise can cause a euphoric state resulting from a rise in blood concentration of beta -endorphin and improve the perception of the pain of dysmenorrhea.
