Abstract
Background : Cardiovascular diseases are among the most important causes of mortality and major health problems in developed as well as developing countries including Iran. This study aimed to develop percentile reference data for serum lipids including total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride and to determine the prevalence of overweight and fat distribution in male adults living in Tehran. Materials and Methods: The study population consisted of 141 men aged 18-34 years living in district 6 of Tehran.According to list of primary schools located in district 6 of Tehran, subjects were chosen from residents around these schools. Sociodemographic and anthropometric questionnaires were filled in at the subjects' home. They were asked to attend the study center the next day at 8:00-8:30 am and 5 ml of fasting blood (at least 12 hours) was collected from each subject. Data statistical analysis was performed using SPSS software Ver 11.5. Chi square test was used for qualitative variables and Pearson correlation was calculated for quantitative variables. Results: Data showed 24.8% hypercholesterolemia, 29.8% hypertriglyceridemia, 21.3% LDL>130mg/dl and 36.2% HDL<40mg/dl in the subjects. BMI was positively and significantly correlated with total cholesterol, triglyceride and low density lipoprotein cholesterol but no significant correlation was observed for waist circumference and waist to hip ratio with blood indices. Conclusion: The study shows that BMI can be a predictive factor for cardiovascular disease in Iranian population. In order to clarify waist circumference and waist to hip ratio correlations with and blood lipids and also to develop percentile reference data for blood lipids, more studies with larger study population is recommended.

Volume 19, Issue 1 (6-2017)
Abstract

Background : Obesity and overweight are related to biological factors, individual, social, economic factors, different cultural factors and feeding behavior.  Recognizing these factors can be a guidance of interventions relating to prevention and control of obesity in children and teenagers. The present study was aimed to study determinant factors of obesity and overweight in students of Khorramabad city.

Materials and Methods: In this cross-sectional study, 3387 students from age 6 to 14 were selected by combinative, multistage grouped and clustered sampling. Students' height and weight were measured and also body mass index (BIM) was calculated. In order to determine  the  prevalence, body mass index was used  for age in NCHS table and evidence up 95 was regarded as obese and 85 to 95 was regarded as overweight.    

Results: The relation of overweight and obesity in students with kind of school, family size, parental education and family income was very significant     (p<0.001). Obesity and overweight were more prevalent in students of non-profit schools and families with more income. Students whose parents had higher education, the prevalence of overweight and obesity was more. There wasn't  a significant relation between overweight and obesity and pubertal status (p=0.1).

Conclusion: Overweight and obesity in case study students were related to individual and external factors. Of these factors, we can mention factors such as gender, birth rank, family size and parental education.

Volume 20, Issue 1 (4-2018)
Abstract
Background: Orexin neurons drive arousal and motivated behaviors in response to stress. The aim of the study was to investigate the effect of eight weeks of pilates training on serum levels of orexin and insulin resistance in overweight children.
Materials and Methods: 20 overweight children (10 - 13 years old) were selected from volunteers using purposive sampling, and randomly divided into two groups: Pilates exercise (n= 10) and control (n= 10) groups. Physiological characteristics were measured in both groups. Blood samples were taken before and after eight weeks of Pilates training program to measure the variables of the research. Independent t-tests were used to examine intra-group and inter-group variations of the research.
Results: The findings by paired t-test results showed that Pilates exercise causes a significant increase in orexin (P=0.001). It was also found that eight weeks of Pilates exercise significantly reduced insulin resistance, insulin and glucose (P=0.001). In contrast, the control group had a significant increase in insulin resistance (P=0.001), insulin (P=0.001) and glucose (P=0.027). In addition, eight weeks of pilates training had a significant effect on body weight (P=0.001), fat percentage (P=0.001) and body mass index (P=0.001). It was also found that the control group had a significant increase in body weight, body fat percentage and body mass index.
Conclusion: The results show that eight weeks of pilates training is effective in increasing serum orexin, insulin resistance, insulin and glucose, as well as improving body composition in overweight children.

Volume 20, Issue 4 (1-2019)
Abstract
Background: Coronary artery disease (CAD) is a leading cause of mortality and disability in Iran and obesity is considered as one of the main causes. The purpose of this study was to compare the effect of aerobic training and turmeric supplementation on cardiovascular risk factors in overweight women.
Materials and Methods: In this study, 40 healthy non-athlete women with an average age of 23.23±2.98 years were randomly divided into four groups of training- curcuma longa supplement (n=10), training-placebo (n=10), turmeric supplement (n=10) and placebo (n=10). Aerobic training program consists of three sessions of running per week with 45-55 percent of target heart rate for 8 weeks. Supplement group consumed 1 gr/day turmeric. Before and after the intervention, TC, TG, HDL-C and LDL-C were measured.
Results: All three groups (aerobic training, turmeric supplementation, and aerobic training + turmeric supplementation group) showed a significant reduction in weight, BMI, TC, TG and LDL and an increase in HDL (P<0.05). Also, the results show that aerobic training + turmeric supplementation group compared with aerobic training, turmeric supplementation significantly caused reduction in TC, TG and LDL and an increase in HDL (P<0.05).
Conclusion: The results showed that 8 weeks of aerobic training with turmeric supplementation is more effective in the overweight women’s cardiovascular risk factors and body composition than either aerobic training or turmeric supplementation alone.

Volume 23, Issue 3 (8-2021)
Abstract
Background: Proliferation of adipose tissue increases leptin secretion and decreases adiponectin concentration. Exercise is an intervention to control and reverse this process. Therefore, the present study aimed to determine the effect of 8-week high-intensity interval training on leptin, adiponectin, and the ratio of leptin to adiponectin in overweight adolescent boys.
Materials and Methods: The present quasi-experimental study was conducted on overweight adolescent boys (13-18 years old, mean body mass index 27.05±1.4 kg/m2). A total of 30 participants volunteered who were divided into three groups of 10 people including short-term (9 sessions of 30-second training with 150-second rest), long-term (4 sessions of 150-second training with 240-second rest), and control group. The training groups performed high-intensity running sprints 3 times per week for 8 weeks. Data were analyzed using two-way repeated-measures ANOVA (3 groups×2 measurement times) and Bonferroni test.
Results: Performed high-intensity interval training failed to affect leptin, weight, and body mass index but increased adiponectin and decreased the ratio of leptin to adiponectin (P = 0.042) and fat percentage. No difference was observed between the two types of interval training in changing the level of leptin, adiponectin, fat percentage, and body mass index.
Conclusion: High-intensity interval training increases metabolic benefits in overweight adolescents by increasing adiponectin and subsequently decreasing the leptin/adiponectin ratio. Low exercise, no calorie restriction, and other factors affecting puberty may influence the research results.

Volume 23, Issue 3 (8-2021)
Abstract
Background: The fibroblast growth factor 21 is a protein that is involved in regulating glucose and fat metabolism. The present study aimed to investigate the effect of eight weeks of high-intensity interval training on serum levels of fibroblast growth factor 21 and insulin resistance in overweight young men.
Materials and Methods: In this semi-experimental study, 30 overweight young men (BMI<25 kg /m2) were purposefully selected and randomly divided to control (n=15) and experimental (n=15) groups. The experimental group performed ten repetitions of one-minute aerobic exercise (treadmill, elliptical trainer, or stationary bike) with an intensity of 80-75% of the target heart rate with one-minute active intermittent rest periods with an intensity of 35-40% of the heart rate for 8 weeks, 4 sessions per week. Fibroblast growth factor 21 and insulin resistance were measured 24 hours before starting the program and 48 hours after the last training session. Intragroup and Intergroup changes were analyzed using dependent and independent t-test, respectively.
Results: Serum levels of fibroblast growth factor 21 indicated a significant increase (t=6.94, P= 0.031) compared to that of the control group after 8 weeks of high-intensity interval training, but insulin resistance significantly decreased (t=5.81, P=0.008).
Conclusion: High-intensity interval training for 8 weeks can be prescribed as an optimal exercise protocol to increase serum fibroblast growth factor 21 and reduce insulin resistance in overweight young men.

Volume 24, Issue 1 (4-2022)
Abstract
Background: Trampoline rebound is one of the recent interesting exercises. The present study aimed to investigate the effect of six weeks of trampoline rebound exercises on cardiovascular indices, body mass index, and lipid profile of obese and overweight women.
Materials and Methods: The statistical population of the present quasi-experimental study consisted of 20 obese and overweight women in Zahedan ( (BMI) ≤27.5 kg/m2), and randomly assigned to two groups of exercise (n=10) and control (n=10). The subjects participated in four 90-min sessions of rebound trampoline exercises for six weeks using a trampoline mat. Physiological, BMI, and lipid parameters were measured in two stages of pre-test and post-test. Data were analyzed in SPSS software (version 21) using independent and dependent t-test, as well as an ANCOVA test. A p-value less than 0.05 was considered statistically significant.
Results: The results demonstrated a significant decrease in post-test values ​​of LDL (from 92.90±1.52 to 73.10±3.81), cholesterol (from 182.10±1.96 to 166.30±6.32), triglyceride (from 108.30±1.33 to 95.30±5.35), and body mass index (29.44±1.07 to 27.38±1.02), as well as a significant increase in HDL (from 59.60±2.75 to 77.00± 3.09) and Vo2max (from 45.50±1.31 to 57.80±1.31) in posttest of the training group, compared to their pre-test (P<0.05). Furthermore, there were the same changes in these parameters in the exercise group, compared to the post-test values ​​of the control group (P<0.05).
Conclusion: As evidenced by the results of this study, six weeks of trampoline rebound training had beneficial effects on controlling lipid profile, cardiovascular indices, and body mass index of obese and overweight women. This training protocol is suggested to improve these indicators in the same groups with obesity and overweight, especially for the variety of exercises.
