Background: Obesity in patients is followed by decreased kidney function and leads to renal damage in healthy people. The aim of this study was to investigate the effect of aerobic exercise with and without green tea consumption on kidney function in sedentary postmenopausal women.Materials and Methods: Out of 60 volunteers, 29 sedentary postmenopausal women with a body mass index higher than 25 kg/m2 were randomly divided into three groups, exercise, supplement and exercise+supplement. Aerobic exercise program was performed for 8 weeks, 3 sessions per week and each session for 45 minutes at 65-75 % of maximum heart rate. Supplement groups consumed 6 g of green tea powder in 600 ml of almost boiling water (80 °) daily and one hour before their meals for 8 weeks. Combined group performed exercise and consumed supplement, simultaneously.Results: In supplement group, creatinine levels (p=0.048) decreased significantly; While none of the variables in exercise group (uric acid (p=0.432), urea (p=0.681) and creatinine (p=1)) and exercise+supplement group (uric acid (p=0.597), urea (p=0.270) and creatinine (p=0.235)) had no significant change. Between groups changes in any of the variables was not significant too.Conclusion: Eight weeks of aerobic exercises in water alone and in combination with green tea consumption did not improve renal function in obese and overweight postmenopausal women, while green tea consumption alone decreased serum creatinine and improved renal function.

Background:Neurotrophin-3 is among the biomarkers studied in MS.Regarding the fact that Exercise training has been proposed as an effective non-drug way of treating Multiple Sclerosis(MS),the present study aims at investigatingthe effect of eight weeks’ aquatic exercise and resistance training programs on the plasmatic levels and gene expression of neurotrophin-3in MS patients.Materials and methods:To the aims of the present study,30women with MS were randomly selected and assigned to three groups:the control group,resistance training group,and aquatic exercise group. Resistance training and aquatic exercise programs were used for 8weeks.After separating plasma and PBMNcells,plasmatic levels and the expression of neurotrophin-3gene were measured via ELISA and real-timePCR,respectively.Inorder to compare the means,plasmatic levels and the gene expression of neurotrophin-3of the three groups were Analyzed by the ANCOVAtest at the significance level of p≤0.05through SPSS18. Results:The results showed a significant increase in plasma levels neurotrophin-3of the three groups (p=0.001).The Scheffe post hoc test was significant in two by two comparisons of the aquatic group and resistance training group with the control group (p=0.001,p=0.001,respectively).However,the difference between the aquatic and resistance groups was not significant(p=0.329).Moreover,there was a significant increase in the gene expression of neurotrophin-3of the three groups(p=0.001).Based on the Scheffe test,the mean differences between the aquatic and resistance groups,and the control group were(p=0.053,p=0.001,respectively).However,non-significant differences in the gene expression of neurotrophin-3were shown between the aquatic group and the resistance group(p=0.08).Conclusion:The findings of the present study indicated that both the resistance training and the aquatic exercise can increase plasmatic levels and the gene expression of neurotrophin-3in MS patients.

Background and aim: Pain is one of the most common reasons that oblige people to refer to a doctor. With regard to beta-endorphin effect on pain reduction, the aim of this study is investigation of the effect of beta -endorphin serum level on amendment of dysmenorrhea factors after eight weeks aerobic exercise. Materials and Methods: This is a Clinical Trial. The sample included 22 subjects with moderate to severe dysmenorrhea, which randomly divided to two control group (n=10) and exercise group (n=12). Aerobic exercise program included aerobic activity with severity of 60-75% of maximum heart rate for 24 sessions (three sessions per week, each session lasting 45-60 minutes). Serum level of beta-endorphin was measured before and after the exercise intervention. Dependent and independent student t-test was used to investigate the intragroup and intergroup differences of beta-endorphin. Pearson correlation test was used to estimate the relation of variables of study. Results: Findings of study showed that exercise intervention made a significant increasing on the serum level of beta-endorphin. Also there is a significant negative relationship between serum level of beta-endorphin and intensity and perception of pain. But any significant relation with duration of pain was not observed. Conclusion: In general, it seems that increasing of beta-endorphin levels, which was created following the exercise, can have a role in analgesia and reduction of the indicators of dysmenorrhea pain.

Background and Objectives: Aerobic training can be affected in polycystic ovary syndrome (PCOS) which is one of the most common endocrine disorders in women. However, it's worth saying that different intensities of aerobic exercises for curing the disease is in ambiguous. The purpose of this study was to evaluate the effect of eight weeks aerobic training with different intensities on levels of insulin, fasting glucose and insulin resistance in female rats with polycystic ovary syndrome.
Materials and Methods: In this experimental study, forty adult eight-week rats with Wistar race (185±22 gr) after induction of PCOS, divided into four groups: healthy control, polycystic control, low-and moderate-intensity groups. They took part in eight-week program of aerobic exercise with 45% maximal oxygen consumption (equal 15m/min speed) and 65% maximal oxygen consumption (equal 25m/min speed), within three days a week for two period of 35 minutes with 10 min rest between periods. Data were collected and analyzed by Spss software (version16.0). One way analysis of variance test (ANOVA) was used for comparisons between groups. The level of significance was considered 0.05.
Results: The results showed that there were no significant differences in the level of insulin and glucose in any groups. Insulin resistance in polycystic moderate intensity group compared to control PCOS group had a significant reduction (p=0.035).
Conclusion: According to the results, it seems that aerobic exercise with moderate intensity and with reduction of insulin resistance can be considered as a non-pharmacological treatment method for recovery polycystic ovary syndrome patients.

Background: 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.
Materials and Methods: 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.
Results: Our findings showed that exercise intervention significantly increased serum levels of beta - endorphin and decreased pain perception index.
Conclusion: 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.
