Introduction: In obesity, the serum levels of Asprosin are pathologically upregulated, this is thus considered a therapeutic target. This study aimed to explore the effect of exercise training as combined training (Aerobic+ Resistance training) along with Caffeine supplementation on the plasma levels of Asprosin in middle-aged obese men.Materials and Methods: 38 obese men aged 35 to 50 years, with a BMI of greater than 28 participated in the research. They were stratified randomized into 4 groups. including: 1-Control-placebo (n=10), 2- Caffeine (n=10), 3- Combined training-placebo (n=9) and 4- Caffeine and combined training (n=9). The caffeine group consumed the caffeine tab 4.5 mg per kg body weight, daily, for 6 weeks. The Combined training group had concurrent aerobic and resistance training for 6 weeks (3 sessions per week). Blood samples were collected before and after the intervention, and the plasma asprosin concentration was measured by the ELISA method.Results: By the effect of the Combined training, the Asprosin level was reduced (p=0/01). Taking Caffeine alone did not significantly reduce Asprosin (p=0/19). The Asprosin declined in the group that had both Combined training and Caffeine (p=0/01).Conclusion: In order to reduce the upregulated Asprosin in obese individuals known as pathologic, combined training is recommended and/so it is not necessary to take caffeine along with the training.

Introduction: Misperception of body weight and lack of awareness about overweight and obesity are associated with poor weight management behaviors.Materials and Methods: This cross-sectional study included 350 female students from Shahed University, Tehran, Iran, using a convenience sampling method. Data were collected through anthropometric measurements and self-reported answers regarding weight perception and level of body weight preoccupation. Data analysis was conducted using Spearman’s rank correlation coefficient.Results: The findings revealed that 51.43% of the subjects misperceived their body weight. Among them, the majority (92.22%) underestimated their weight. Additionally, 17.14% of the overweight and obese subjects perceived their weight to be within the normal range, while 29.6% of obese subjects perceived themselves to be only slightly overweight. Furthermore, there was a significant relationship between body weight perception and anthropometric indices (p<0.01). The body mass index (r=0.739), C-index (r=0.648), body adiposity index (r=0.620), abdominal volume index (r=0.552), and waist-to-height ratio (r=0.537), and waist circumference (r=0.533) had the highest correlation with body weight perception, respectively.Conclusion: The high rate of unawareness of actual body weight among female university students is alarming. It is, therefore, necessary to develop programs that increase awareness about normal body weight and the importance of anthropometric indices in weight management.

Background and Objective: Obesity and overweight have become a global problem. Obesity is increasing sharply, especially in Iranian women. Experts believe that diet and drugs alone are not enough to treat and control sugar and blood fat metabolism of patients, but physical and sports activities should also be added to the daily schedule.Materials and Methods: The current research is a semi-experimental type with a pre-test and post-test design. 40 overweight women were randomly assigned to four groups of combined exercise, combined exercise-supplement , supplement and control. Aerobic training was performed for 8 weeks and three sessions per week with 50-75% of the maximum heart rate and TRX training in the range of 12 to 17 pressure perception on the Borg scale. 24 hours before the start of training and 48 hours after the end of the last session, blood was taken to measure leptin and visfatin. Then, analysis of covariance (Ancova) test was used for inter-group changes and paired correlation T-test for intra-group comparison. Data analysis was done by SPSS version 25 software at a significance level of P<0.05.Results: The results show a significant decrease in leptin (p=0.001) and visfatin (p=0.001) values, and the changes for the exercise and exercise-supplement group were more than the cinnamon supplement group.Conclusion: According to the results of the current research and since combined exercise has a beneficial effect on leptin and visfatin compared to supplements, it can be recommended that overweight people use combined exercise to lose weight.

Introduction: Sleep deprivation is one of those factors that affect the energy intake and appetite of individuals. It is reported that sleep deprivation affected by certain hormones (e.g. insulin, Leptin, ghrelin, and cholecystokinin, etc.) that are involved in energy balance may affect body weight through appetite. The purpose of this study was to investigate the effect of 30-hours sleep deprivation on the response of leptin and ghrelin levels to an Exhaustive activity among active male students.Materials and Methods: Among the active male students of Razi University of Kermanshah, 20 undergraduate students were selected through convenience sampling and participated in the study. Subjects were evaluated by simple randomized cross-sectional design in two situations.Results: Information related to the comparison of post-test and pre-test in two experimental (sleep deprivation) and control (adequate sleep) situations showed that leptin hormone in sleep deprivation conditions decreased compared to rest conditions (9.4 %) And ghrelin hormone in experimental conditions increased compared to control conditions (2.04%) and this difference is considered significant at the level (p = 0.0012). Insomnia also caused significant changes in physiological parameters (VO2max, heart rate, blood pressure, time to exhaustion, etc.).Conclusion: 30 hours of sleep deprivation decreased leptin and at the same time increased ghrelin, which indicates the importance of night sleep, which is one of the influential factors associated with obesity and overweight.

Introduction: Obesity is a metabolic disorder that can be controlled and prevented by increasing energy expenditure and stimulating factors related to the browning of white adipose tissue. The aim of this study was to investigate the effect of high-intensity resistance training on Irisin and Fibroblast growth factor 21 (FGF21) levels in overweight men.
Materials and Methods: In this semi-experimental study, 20 overweight men (mean 36.56± 3.33 years and body mass index 29.41± 3.02 kg/m2) were randomly selected. They were assigned in two groups of high-intensity resistance training and control. The program of the Resistance Group was conducted in a circular shape with an intensity of 85-80% of a maximum repetition, three sessions per week for eight weeks. 24 hours before and 48 hours after the training period, serum Irisin levels and FGF21 subjects were measured in the fasting state. Data analysis was performed by correlated t-test and ANCOVA at the significance level of P<0.01.
Results: Irisin and FGF21 Serum levels in the high-intensity resistance training group showed a significant increase compared to the control group (P<0.01). Bodyweight, BMI, and body fat percentage in the high-intensity resistance training group showed a significant decrease compared to the control group, while a significant increase was observed in the control group (P<0.01).
Conclusion: It seems that high-intensity resistance training can be emphasized as an effective step in convert white adipose tissue to brown and improving the body composition of overweight and obese people.

Introduction: Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders in women of infertility. Women with PCOS are at high risk for early cardiovascular disease. The aim of this study was to evaluate the oxidative stress, inflammatory factors and other cardiovascular risk factors in patients with PCOS. Materials and methods: In this case-control study, 50 women with PCOS and 50 healthy women referred to Zahedan Infertility Clinic who were matched for age and BMI were selected by convenient sampling method. Anthropometric parameters, biochemical tests, C3 and C4 complements, TAC and MDA levels were measured in all subjects. Data were analyzed using independent t-test and analysis of variance at the significant level P Results: Results showed that mean waist circumference (P = 0.048), systolic blood pressure (P <0.01) and diastolic (P = 0.048), serum LDLC levels (P = 0.05) and MDA (P <0.0001) were significantly higher in women with PCOS and serum HDL-C levels (P = 0.03) and TAC (P = 0.05) were significantly lower than control group. Mean serum levels of C3 and C4 were higher in the PCOS group than in the control group, but this difference was only significant for C3 (P = 0.03) . Conclusion: The findings showed that levels of dyslipidemia, oxidative stress and inflammatory factors were higher in PCOS women with abdominal obesity. Thus, screening of these factors and weight management, especially in obese women with polycystic ovary syndrome, is recommended in treatment strategy.

Introduction: Childhood obesity is associated with an increased risk for several metabolic and cardiovascular complications, and is now considered as a state of chronic low-grade inflammation. The aim of this study was to invistigate of the effect 8 weeks of regular aerobic exercise on the Tumor necrosis factor alpha (TNF-α) and lipid profile in obese girls. Materials and Methods: This semi experimental research, 14 obese girls (mean age 9.9±1.18 year) whose body mass index was 95% or greater were selected and assigned randomly to two equal groups as follow: exercise and control groups. Aerobic exercise was consisted of exercise movements at 50% to 70% maximal heart rate and 3 sessions/week for 8 weeks. Fasting blood samples were collected before and 48 hour after the last intervention. The serum levels of TNF-α, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol (LDLC) and high density lipoprotein cholesterol (HDL-C) were measured. Data were analyzed by paired and independent t tests. The level of statistical significance was set at p < 0.05. Results: Eight weeks of aerobic exercise caused a significant decrease in TNF-α, triglycerides, total cholesterol, LDL-C and an increase in HDL-C levels (p < 0.05). Compared with the control group, the percent changes of these variabls in exercise training group were significantly greater (p < 0.05). Conclusion: Aerobic exercise as a non-medical therapeutic intervention for obese children can leads to reduced cardiovascular and metabolic diseases risk factors by improving lipid profiles and a reducse in systemic inflammation.

Background: Incidences of overweight obesity are increasing in the world and it is an alarm for health community. The present study was designed to investigate the relationship between dietary habits with body mass index in Urmia. Materials and Methods: In this study, 453 female students were selected by multi-stage sampling. Anthropometric indices including height, weight and waist circumference were measured using standard methods and calibrated instruments. The dietary habits were determined using a researcher-made questionnaire. Results: In this study, the frequency of side activity during meals was significantly higher in overweight and obese individuals than in subjects with normal weight (P = 0.034), and physical activity significantly higher in subjects with normal weight than overweight and obese (P = 0.001). Consumption of breakfast every day before going to school (P = 0.04), eating three meals regularly (P = 0.003), and healthy snack at school (P = 0.05) were directly related to underweight. In the multiple logistic regression model only eating three regular meals (OR = 1.837, 85% CI (1.35-2.51), P = 0.005) had a direct association with underweight. Conclusion: The results of this study show that side activity during meals increased risk of overweight and obesity. Eating all three meals regularly and eating breakfast every day before going to school were associated with an increased risk of underweight.

Background: Obesity in children and adolescents and adults is one of the most serious public health concerns in the 21st Century. Meanwhile, adolescence is an important stage in creating healthy eating habits, which is usually maintained until the end of life. The present study was designed to investigate the relationship between dietary patterns with body mass index in adolescents female in Urmia.
Materials and Methods: In this study, 453 female students were selected by multi-stage sampling. Anthropometric indices including height, weight and waist circumference were measured using standard methods and calibrated instruments. The usual food intake was determined using a semi-quantitative FFQ.
Results: In this study, three major dietary patterns were identified among female students. The "traditional" pattern included fruits, nuts, dried fruits, can and jams, pickles, tea and coffee, honey, vegetables, and sweets. The "high protein" pattern included legumes, organ meats, fish, egg, red meat, high-fat dairy products, cereals, and vegetables. The pattern of "fast foods and salty snacks" included the high-consumption of soft drinks, fast foods, salty snacks, sweets, sugars and juice. High protein dietary pattern [(second tertile compared to first one: (OR = 1.8, 95% CI = (1.1 - 3), P = 0.016) and third tertile compared to the first one: (OR = 1.6, (95% CI = 1.01- 2.7, P = 0.046)] were directly related to underweight. This significant association was maintained in the multiple logistic regression model (Tertile 2 vs. tertile 1: OR = 1.66, 85% CI (1.15-2.39), P = 0.048).
Conclusion: The results of this study show that a high protein diet was associated with an increased risk of underweight.

Background: Regular exercise training has been postulated as an important strategy to reduce inflammatory markers, but it is still not clear what type of training is most appropriate. The purpose of this study was to compare the effects of nonlinear resistance training (NRT) and aerobic interval training (AIT) on interleukin-18 (IL-18) and C-reactive protein (CRP) in obese young men. An additional aim was to compare the inflammatory markers between the obese and non-obese men to determine the obesity effect. Materials and Methods: Thirty-eight obese and young men (age=31.4±5.2 year, body fat%=27.3±1.5) were randomly assigned to NRT (n=14), AIT (n=12) and control (CON, n=12) groups. An age-matched control group of non-obese men were also recruited for baseline comparison. Independent t-test and 2-factor repeated measures analysis of variance (ANOVA) were used for analyzing data.Results: No significant differences were noted at baseline between obese and non-obese men for IL-18 (P=0.17), CRP (P=0.77) and VO2peak (P=0.24). After training, VO2peak increased in NRT (P=0.03) and AIT (P=0.001) compared to the CON, but in AIT more than in NRT (P=0.02). Compared to the CON, both of training were equally effective at reducing fat mass (P=0.001). However, there were no significantly changes in IL-18 (P = 0.26) and CRP (P=0.15) after training. Conclusion: Lack of significant differences for IL-18 and CRP between obese and non-obese men might be due to the similar status in age and aerobic fitness. It seems that 2 exercise programs could not make a significant reduction in the concentrations of inflammatory markers.

Sleeping is the most important circadian rhythms and one of the fundamental human needs. Approximately, one third of one's life is spent in the sleep. Insufficient sleep has been widespread in the modern society and a large number of people are suffering from it. People with sleep disorders in addition to fatigue are experiencing the defect in cell regeneration, difficulty in thinking, learning and memory, increased stress and reduced the daily performance on behavior. In most cases, disruption in the sleep cycle is an early symptom in the various diseases. Several studies have shown that the sleep disorders are associated with the incidence and intensifying of diseases, and the improvement of sleep quality in different ages, especially in the adulthood, helps them to avoid the risk of chronic diseases during life. According to evidence and the impressive impact of sleep on health and quality of people’s life and also reducing the quality and quantity of sleep in the modern society, this study examines the importance of sleep and its effect on health, especially the role of sleep in the prevention of metabolic diseases.

Background: The prevalence of obesity is increasing as threatening in all age group in the world so it has became the serious problem in the public health ,Nowadays, the use of medicinal plants has have been considered more than other methods of weight control, the green tea is considered one of these plants that So far the researches have been done on its effects on weight But the results of these studies have been inconsistent due to various doses and different methods so, this study was conducted to determine the effect of various doses of green tea extract on weight loss and body mass index in adults obese women.
Materials and Methods: This double-blind clinical trial has randomly been conducted on 60 obese women that were overweight, with a BMI> 27 kg/m2, WC> 87 (waist). The samples were divided randomly into three groups of 20; in this regard, have received two intervention groups (experimental) recipient of green tea extract with different concentrations (50 and 100 percent) and control group (control) recipient of placebo containing cellulose. Each participant received daily three times (one hour before each meal) of green tea extract or placebo for 12 weeks. All samples were measured in the baseline and weeks 2, 4, 6, 8, 10 and 12 in terms of anthropometric measures (weight, height, waist circumference, hip circumference, body mass index (BMI) and waist-hip ratio (WHR). the data were collected and have been analyzed in the different groups By using of software SPSS 19 - Sas9.2 and statistical test of one-way Anova and was used repeated Measurement test for Comparisons of these groups
Results: In the baseline The mean and standard deviation of weight and BMI were in the experimental group which received 100% of extract, respectively74.19 ± 4.3 and 28.95 ± 0.8 and in the experimental groups which received extract 50% 1/5 ± 34/74 and 06/1 ± 69/28., which was reduced respectively, to 67.90 ± 4.1 and 26.49 ± 0.7 as well as 70.98 ± 5.6 and 27.38 ± 1.19 in the end of the study Which is indicative of a significant difference in the mean weight and BMI on these consecutive weeks(P < 0.01،P

Abstract
Introduction: Visfatin is a newly discovered adipokine which increases with obesity. It is not clear whether endurance training which induces changes in adipose tissue and blood lipids might decrease the plasma level of visfatin as well. The aim of this study was to investigate the effect of 9 weeks of aerobic training on serum visfatin level and insulin resistance index in obese women.
Materials and methods: Method of research was semiexperimental. Twenty-eight obese female volunteered and were randomly divided into experimental (14 subjects with means of weight 82 ± 10.2 kg, and BMI 34.2 ± 4.3 kg/m2) and control (14 subjects with means of weight 79.9 ± 9.5 kg, and BMI 34 ± 3.9 kg/m2) groups. Aerobic training protocol consisted of 4 sessions per week for 9 weeks. Each training session was a slow running trial at intensity of 65 to 75 percent of maximal heart rate for a period of 15 minutes. To follow the principle of overload, half-a-minute was added to each session after the second week, so that, at the last session the running time reached to 31 minutes. Before and after the training period, blood sampling was performed. Data were analyzed using independent t test and ANCOVA.
Results: Results showed significant reduction of serum visfatin level (p < 0.05), and no significant difference in insulin resistance index, serum HDL, LDL, TC and TG between the control and experimental groups (p > 0.05). In addition, aerobic training reduced significantly body mass index, body weight, waist to hip ratio, body fat percent, and increased significantly maximum oxygen uptake (p < 0.05).
Conclusion: It can be said that 9 weeks of aerobic training can cause significant reduction of serum visfatin and no significant change in insulin resistance index in obese women.

Background and Purpose: Obesity is associated with various metabolic and inflammatory impairments، the effects of which have not been sufficiently studied. Therefore، the purpose of this study was to examine the influence of an 8-week strength training and aerobic training program and a 10-day detraining on lipid profile and CRP in obese girls. Methods and Materials: In this experimental study، thirty-six obese female university students were voluntarily recruited and randomly assigned into three groups: control (n=11)، aerobic training or AT (n=12) and strength training or ST (n=13). ST and AT groups trained for 8 weeks، 4 times/week، 60 min/session، with 60 to 70% of 1 repetition maximum for ST، and 65 to 75% of HRmax for AT. Blood samples were taken at baseline، 24 hours after the last exercise session and after 10 days of detraining on fasting state. Data were analyzed in SPSS 16 using repeated measure analysis of variance (RM-ANOVA). The alpha level was established at P0.05). Also، no significant differences were found between the three groups (P>0.05). TC also decreased in AT and ST groups (9% and 19%، respectively); however، the change was not significant (P>0.05). After training no significant changes in HDL، HDL2، HDL3، LDL، and CRP were observed (P>0.05). Ten days of detraining also did not result in any significant alterations in the lipid profile or CRP (P>0.05). Conclusion: Eight weeks of aerobic and strength training have no significant effect on the lipid profile and CRP in obese girls.

Background and purpose: C-reactive protein is a sensitive, nonspecific marker of inflammation and its relationship with coronary vascular disease is already established. The present research was conducted to study the effect of resistance training on the rate of C-reactive protein in obese men.
Methods and Materials: The present study was quasi-experimental and 24 male subjects (16 obese, 8 lean) with age range of 35 to 48 years voluntarily participated in the study. Obese men were randomly assigned into two groups: resistance training and control group. The third group included the lean men subjects. Fasting blood samples were taken from all subjects. The experimental subjects received resistance training for 13 weeks, 3 sessions per week. The resistance training was done in circuit fashion in 11 stations with a 50 to 60% intensity of one maximum repetition (IRM).
Results: Resistance training significantly decreased the serum CRP levels of the obese men (from 1.65±0.6 to 0.53±0.73). In addition, serum CRP concentrations in obese men at baseline state were significantly higher than those in lean men (1.56±0.58 versus 0.26±0.21). In all subjects there was a significant and positive correlation between serum CRP levels and obesity markers (r=0.75) and different components of the metabolic syndrome.
Conclusion: Resistance training due to antinflammatory effects is likely to reduce the risk of future cardiovascular events in obese men.
