Read More Aim: Retinol binding protein-4 (RBP-4) as an adipokine secreted from adipose tissue, plays an important role in insulin resistance and metabolic disorders. Despite the benefits of aerobic training on metabolic disorders, the effect of aerobic training on RBP-4 and its relation with metabolic factors in patients with metabolic syndrome is unclear. Therefore, the aim of this study was to investigate the effect of eight weeks aerobic training on serum RBP-4 levels and insulin resistance in women with metabolic syndrome. Methods: In a semi-experimental study, 24 women with metabolic syndrome (age: 52.79±4.91 yrs, BMI: 32.77±2.37 Kg/m2 and VO2peak: 40±2.55 L/min) were randomly assigned into two groups including exercise (n=12) and control (n=12) groups. Aerobic exercise program was performed for 8 weeks, 3 sessions per week with an intensity of 50-60% of peak oxygen consumption for 20-40 minutes. Prior to the experimental period and 48h after last training session, body composition measurements were performed and blood samples were taken to be measured for serum levels of RBP-4, lipid profile, glucose and insulin. Insulin resistance index was also assessed. The data were analyzed using statistical tests of Paired and Independent t-test and Pearson's correlation test at significance level of PResults: The results showed that aerobic training significantly decreased serum RBP-4, glucose, insulin resistance index, body weight, body fat percentage, body mass index (BMI), waist circumference and metabolic syndrome Z score (P<0.05). Moreover, high density lipoprotein HDL - C levels significantly increased following eight weeks aerobic training (P<0.05). Pearson's correlation test revealed that changes in RBP-4 levels was significantly correlated with changes in body fat percentage, triglycerides, insulin and insulin resistance index (P<0.05). Conclusion: Overall, the results of this study indicated that aerobic training can reduce the RBP-4 levels and improve insulin resistance and some metabolic risk factors in women with metabolic syndrome. Insulin resistance improvement is likely to be resulted from decreased RBP-4 levels following aerobic training.

Read More Objective: The aim of the present study was to investigate the effect of 10-week negative energy balance (NEB) methods on adipocyte size and adiponectin levels in different abdominal fat depots as well as glucose and lipid variables and insulin resistance in high-fat-diet obese male wistar rats. Methodology: Study sample were consisted of sixty-four Wistar male rats (average weight; 194.5±12.6g). Blood samples were collected at 1st, 18th and 28th weeks after an overnight fasting. After first sampling, remaining 56 rats were randomly divided into control (n=16) and high-fat-diet (n=40) groups. After 18 weeks High-fat-diet group randomly divided into high-fat-diet (HFD) and negative energy balance consisted of calorie restriction, exercise training and combination (exercise training with calorie restriction) subgroups. Negative energy balance subgroups underwent an aerobic training (running) with intensity of 70 to 75% of VO2max, %25 calorie restriction and interval of both methods for 10 weeks. Adiponectin Levels and adipocyte size in retroperitoneal and mesenteric fat depots, insulin and glucose levels and lipid profile were measured. HOMA-IR was also calculated. Results: The results of this study indicated that in comparison to high-fat-diet, negative energy balance methods despite consumption of high fat diet, decreased adipocyte size in retroperitoneal and mesenteric fat depots (P<0.05) and insulin resistance index improved in line with decrease of serum concentrations of insulin, glucose and triglyceride in obese male rats (P<0.05). However although lipid profile improved, only triglyceride concentration significantly decreased (P<0.05). From negative energy balance subgroups only combination showed significant increase in adiponectin levels of studied depots compared to high-fat-diet (P>0.05). Conclusion: This study indicated that negative energy balance methods can actually decrease adipocyte size of retroperitoneal and mesenteric fat depots even with simultaneous consumption of high-fat-diet which is largely congruent with improvement in lipid and metabolic profile Results also indicate a superiority of aerobic training in improving the lipid profile compare to other NEB methods.

Read More Objective: The aim of this study was to investigate the effect of aerobic-resistance training on visceral adipose tissue, serum omentin-1 and insulin resistance in ovariectomized (OVX) rats. Methodology: Fifty Female Wistar rats (weight, 180±5g) were divided accidental and according body weight into five groups: SHAM (n=20) and OVX (n=30) groups. OVX rats were subdivided into 2 Ovx+sedentary (Sedentary; n=20) groups and one aerobic-resistance training (Ovx+Exe; n=10) group. Two weeks after surgery, one group of OVX rats and one group of SHAM rats were sacrificed and omentin-1, insulin resistance and visceral fat were measured. The other OVX rats were randomly divided into the following subgroups: 1) OVX and sedentary (Sedentary); 2) OVX and Exercise (Ovx+Exe). The exercise consisted of 8 weeks of aerobic-resistance exercise (3 days/week, 20 m/min, 60 min/day, 10% slope, Load; 3% body weight, attached to tail), three days a week. After complete anesthesia, the abdominal cavity was rapidly opened and blood samples were collected. All intraabdominal fat were dissected out and weighed immediately. Omentin-1 was measured by rat omentin ELISA kit. HOMA-IR was used to estimate the insulin resistance. Results: There was no significant differences between weights means all groups. After two weeks of surgery, there was no significant difference between visceral fat, omentin-1 and HOMA-IR in SHAM2 compared to OVX2. After eight weeks, combined aerobic-resistance training in Ovx+Exe significantly decreased visceral fat gain induced via ovariectomy by 21/4% compared to the level observed in Sedentary; whereas, visceral fat significantly increased by 92.5% in OVX2 compared to SHAM2 (p<0.05). Omentin-1 increased in Ovx+Exe compared to Sedentary and SHAM, by56/5% and51/6%, respectively; whereas it was significantly decreased by3/1% in Sedentary compared to SHAM (p<0.05). HOMA-IR induced via ovariectomy significantly decreased by74.7% in Ovx+Exe compared to Sedentary; whereas, it significantly increased by 193.7% in OVX2 compared to SHAM2 (p<0/05). Also, HOMA-IR decreased in Ovx+Exe compared to SHAM2, but it was n ́t significant. Conclusion: 8 week aerobic-resistance training successfully decreased visceral fat and insulin resistance via increasing omentin-1. So, it seems that 8-week aerobic-resistance training with 70-85% Vo2max is suitable for controlling body weight gain, decreasing visceral fat and insulin resistance and increasing omentin-1 in menopause period.
