Introduction: The aim of this study was to evaluate the effect of exercise and Anvillea garcinii extract on sex hormones in male rats with hyperlipidemia.Materials and Methods: 35 male wistar rats randomly divided into five groups (n=7 for each group), including: 1) control group (Con), 2) hypercholesterolemia (Hc), 3) Anvillea garcinii extract (Ext; 100 mg / kg), 4) training group (E), 5) Extract-exercise (E-Ext). Exercise was performed for eight weeks, 30 minutes and three sessions per week equivalent to a speed of 14-17 m / min. Levels of testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin were measured by radioimmunoassay and hormone kits. ANOVA test was used to determine the differences between groups.Results: The results showed a significant difference between the levels of FSH, LH, Prolactin and Testosterone between the groups. The results of Tukey post hoc test showed that FSH, LH and Testosterone levels between E-Ext and Hc groups (p = 0.000) (p = 0.001) (p = 0.001), Ext (p = 0.000) (P = 0.000) (p = 0.008) and E (p = 0.000) (p = 0.011) (p = 0.015) and Prolactin level between E-Ext groups with Hc (0.015). There was a significant difference between Ext (p = 0.046) and E (p = 0.012). The results showed all sexual hormones except Prolactin increased in the E-Ext group compared to the Hc group.Conclusion: Consumption of plant extracts along with exercise can have positive effects on sex hormones.

Introduction: There has been no report on the effect of epilepsy on liver enzymes and lipoproteins and its changes following exercisetraining in epileptic rats with Pentylenetetrazole. Materials and Methods: In this experimental study, 70 male rats were placed in 7 groups. An intact group, three groups of Kindle and three groups of non-Kindle who received PTZ or normal saline injections every 48 hours until the animals were kindled. 24 hours after Kindling, blood samples were collected in intact group and two groups of Kindle and non-Kindle. One Kindle group and one non-Kindle group from the remaining four groups performed aerobic exercise for six weeks, and the other two groups were inactive for six weeks. Blood were collected 24 hours after the 6-week period, and were compared with control groups. Results: After 4 weeks of Kindling period, total cholesterol, triglycerides, low-density lipoprotein, liver enzymes (P <0.001) and antigenic coefficient (P <0.01) increased significantly in the epileptic group. After six weeks of aerobic exercise in Kindle animals; Triglycerides (P <0.001), liver enzymes (P <0.01) and antigenic coefficients significantly reduced, and high-density lipoprotein significantly increased (P <0.01). Conclusion: The results showed that aerobic exercise in epileptic rats with Pentylenetetrazole improved lipid profile impairement and increased liver enzymes caused by epilepsy.

Introduction: The purpose of this study was the investigation of obesity prevalence and some related factors in Bojnord female. Materials and Methods: The samples consisting of 380 females of 3050 years of age, were selected based on random cluster sampling method. A researcher made questionnaire was prepared for gathering data about breeding and obesity. The Beck questionnaire was used to measure the physical activity level. Results: The results showed that the prevalence of obesity and overweight in the female aged 30-50 years of the city of Bojnord were 21.8 and 43.4 percent, respectively. Conclusion: The results also showed that age of the first Parturition (P=0/06), lactation duration (P=0/26), the age of the first menstrual period (P=0/24), TV watching duration in 24 hours (P=0/61), physical activity index during job (P=0/36) and exercising (P=0/21) among three groups were not significantly differnece. Age (P=0/00), children number (P=0/01), pregnancy number (P=0/00), duration of consumption of Oral contraceptive pill (P=0/03), sitting and physical inactivity in female normal weight in comparison with obese female (P=0/01)were significantly lower, and physical activity index in leasure time (P=0/00) and marriage age (P=0/03) were higer. Considering the high prevalence of obesity and overweight in Bojnord, it is recommended that women do more physical activity and further information be made for women about obesity-related risk factors, recognize symptoms and illnesses caused by obesity and ultimately prevent and reduce chronic diseases and their costs resulting from treatment programs should be done

Introduction: Adhesive molecules are cellular markers that identify the process of atherosclerotic plaque formation in the endothelial wall of arteries. The aim was evaluation of changes in E-selectin and P-selectin in men with heart failure after eight weeks of continuous and intermittent aerobic exercise.
Materials and Methods: 42 men with heart failure were selected by sampling method as volunteers and were divided into three equal groups (14 subjects) continuous aerobic, intermittent aerobic exercises and control groups. Continuous training (45-70% of Maximum Heart Rate) and intermittent training (45-80% of MHR with 5-10 minutes rest between each period) were done for 8 weeks (three days a week). Fasting blood samples were taken from all subjects before and after eight weeks of aerobic exercise and adhesion molecules were measured by ELISA method. Data were analyzed by ANCOVA at significance levels of P<0.05.
Results: Comparison of the groups with covariance analysis showed that the levels of E-selectin (P=0.002) and P-selectin (P=0.022) levels was significant in all three groups. The Bonferroni test showed, There was a significant difference between the intermittent and control (P=0.005) and between continuous and control groups (P=0.006) at the level of Eselectin and the intermittent aerobic and control groups (P=0.032) at Pselectin level, However, there was no significant change despite a decrease between the control and continuing aerobic (P=0.083) in Pselecteine. Also, there was no significant difference in the studied variables in both intermittent and continuous aerobic groups.
Conclusion: Aerobic exercise with reducing levels of adhesion molecules may play an important role in the prevention and control of cardiovascular diseases in men with heart failure.

Aim: The aim of this paper is to use a systematic review and meta-analysis to analyze the effectiveness of aerobic and resistance training on blood Flow mediated dilationMethods: In this study, flow mediated dilation was selected as valid index for vascular endothelial function. Search was done in databases PubMed, science direct, Scopus, Web of science, SID, Magiran and google Scholar with specified keywords among articles that were published in the years 1986 to 2016 both in Persian and English. After initial screening, full text search and critical appraisal, studies which pass the inclusion criteria were analyzed.Results: From a total of 1562 articles that were analyzed, 23 received the study inclusion criteria for the systematic review. 14 study, which included 17 trials with meta-analysis inclusion criteria were analyzed. The results of the meta-analysis of studies showed that exercise can improve Flow mediated dilation in healthy subjects (SMD= 0/84, 95 % CI 0/55–1/13, p=0/001) and patients with coronary artery disease (SMD= 0/49, 95 % CI 0/30–0/68, p=0/001). Although the effect size obtained for different sports are different, but considering the low number of studies, we cannot make an absolute statement about the superiority of one method of training.Conclusion: The exercise can be effective in improving endothelial function, although still high-quality research studies with sufficient sample size is needed.

Background: The aim of this research was to study the effects of eight weeks aquatic gymnastics Training on the Intensity of Low Back Pain in primiparous women. Materials and Methods: This cohort study was carried out sampling primiparous women (n=62, age range: 28-35 year) in the second trimester of pregnancy were Purposefully selected and divided into two control (n=30) and experimental (n=32) groups. The experimental group performed a 8 week aquatic gymnastics Training both in water and land in the presence of the researcher, with the collaboration of aquatic gymnastics experts and under the supervision of a medical specialist at specialty hospital of Sarem (Tehran-Iran). The Qubeck low back pain standard questionnaire and Burg exercise intensity measurement scale were utilized to compare the results between the pre-/ post-test. The paired t-test and Covariance were used for analysis by SPSS V.19. Results :The results revealed that a 8 week aquatic gymnastics Training significantly relieved the low back pain and promoted the general health of the primiparous women during the second trimester of pregnancy (P=0.001). The back pain intensity was increased in control group (P=0/023). Conclusion: Based on findings of the present study, as aquatic gymnastics Training can eliminate the low back pain and promote the general health among the pregnants, it can be suggested as a non-aggressive method

Background and purpose: The aim of the present study was to systematic review for the influence of aerobic and anaerobic exercise of the acute and chronic on selected markers of oxidative Stress based on the animal and human studies published in persian journals. Methods and Materials: This present was performed on articles published up to 1 August 2014. Databases such as Magiran, SID and Scholar Google searched for terms: Oxidative Stress, SOD, MDA, Exercise And Training. All the relevant Persian written articles were evaluated by two independent researchers and relevant articles with moderate and high qualities was selected for systematic review. Articles (of total 1163 articles) were evaluated by reading their title, abstracts and full text; 38 full text articles evaluated and only 22 of them fulfilled the inclusion criteria and entered the review. Results: In human studies it was found that regular aerobic exercises lead to a significant and non-significant increase in MDA values. On the other hand, a significant increase was detected in SOD values in the exercising group compared to the control group following 8 weeks of aerobic exercise. However, based on findings from animal research domain, it was found that implementation of at least 8 weeks of aerobic exercise is necessary for down regulation of MDA values and 6 weeks for up regulation of profit values. Conclusion: Present study indicates the lack of high-quality reports on the impact of regular aerobic or anaerobic exercises on resting levels or in response to a bout of intense exercise, especially on human subjects and the few reports of average quality did not also represent a homogeneous finding.

Background: Smoking can decrease adiponectin serum and increase insulin resistance index. The purpose of present study was to examine the effect of one session of exhaustive aerobic exercise on levels of adiponectin serum and insulin resistance index in smoker men.
Materials and methods: A semi-experimental design was used. The target population consisted of smoker students of the Hakim Sabzevari University, from whom twelve smoker male students volunteered and were randomly divided into three situations; control, exhaustive aerobic exercise at 70-75% intensity of maximal heart rate, and exhaustive aerobic exercise at 90-95% intensity of maximal heart rate, in a crossover design.Two situations of aerobic exhaustive exercise programs involved running on treadmill with intensities of 70-75% and 90-95% of maximum heart rate of the subjects. During this period, the control group did not perform any physical activity. To calculate changes in plasma volume and measurement of adiponectin, glucose, insulin and lipid profile indices blood samples were collected before and immediately after performing of aerobic exercises. Data were analyzed using one way analysis of variance (ANOVA).
Results: After the correction of results with respect to plasma volume changes, no significant differences in serum of adiponectin levels (P=0.825) and insulin resistance index (P=0.756) were determined between the control and experimental situations. Furthermore, no significant difference was observed among the three situations in the glucose (P=0.633), insulin (P=0.768), low density lipoprotein (P=0.075), high density lipoprotein (P=0.131), total cholesterol (P=0.559), and serum triglyceride (P=0.641).
Conclusion: One session of exhaustive aerobic exercise with two different intensities has no effect on levels of serum adiponectin and insulin resistance index in smoker men. However, to achieve more conclusive results, further investigation is warranted.

Background and purpose: Recent reports suggest that increased homocysteine is a risk factor for heart disease. On the other hand, regular exercise and supplementation of omega-3 fatty acids have been effective in reducing these diseases. The purpose of this study was to evaluate the interaction effect of 8 weeks of aerobic training and omega-3 fatty acid supplementation on plasma homocysteine concentration in elderly men. Materials and methods: The statistical sample for this experimental study consisted of 36 male non-athletes in the age range of 57.37±3.37 years. They were selected from Genaveh, Iran, and randomly divided into 4 groups: exercise with omega-3 supplements, exercise with placebo, omega-3 supplementation, and placebo intake. The 8-week endurance exercise program included 3 sessions per week with pre-determined duration (30-45 minutes) and intensity (55-70% HRmax). Daily dosage of omega-3 fatty acid supplementation was 2000 mg. Blood samples were taken after 14 hours of fasting before the study and 48 hours after the last training session. Results: The results showed that, despite a decline by 3.6% in the exercise + omega-3 fatty acids group, 12.4% in the placebo + exercise group (due to higher basal values of this group), and 2.8% in the omega-3 supplement group, moderate-intensity aerobic exercise and omega-3 fatty acid supplementation could not create a significant decrease in plasma homocysteine concentration (p≥0.05). Conclusion: This study showed that aerobic exercise and omega-3 fatty acid supplementation are associated with a non-significant but tangible decrease in plasma homocysteine concentration as a new risk factor for cardiovascular diseases.
