Objective: The purpose of this study was to investigate the changes in plasma C reactive protein (CRP) and Serum amyloid A (SAA) levels following 8 weeks of circuit resistance training in obese men. Methodology: Twenty six obese men (age; 36.8±7.9 yr, weight; 92.8±10.8 kg, and BMI; 31.5±2.8 kg/m2) voluntarily participated in this study, and were divided into control (n=13) and resistance training (n=13) groups. Subjects in training group performed eight weeks circuit resistance training with 50-85% 1RM (3 days/week). Anthropometrics parameters, as well as plasma levels of CRP and SAA were measured at the baseline and at the end of study. Results: Eight weeks of resistance training induced significant reduction in body weight, BMI and body fat percentage (P≤0.05). Significant reduction in plasma CRP concentration was found in compare with control group (P≤0.05). Plasma SAA levels increased in both control and training groups when compared with baseline levels (P≤0.05), But there was no significant difference in SAA levels changes between two groups. Conclusion: The results of this study showed that circuit resistance training decreases plasma CRP levels, associated with improved in body composition in obese men.

Aim: The purpose of this study was to investigate the effects of aerobic exercise training on plasma vaspin concentration and insulin resistance index in sedentary overweight women. Methods: Twenty six sedentary overweight women (aged: 43.1 ± 12.6 year, weight: 73.4 ± 10.0 kg, BMI: 29.1 ± 3.2 kg/m2) voluntarily participated in an 8-weeks aerobic exercise training program included running with 40- 80% reserve heart rate, 20- 45 min/day. Anthropometric and metabolic parameters in addition to plasma vaspin concentration were measured at baseline and after 8 weeks of the training program. To compare changes in variables according to body composition alterations, we divided the subjects into responders (defined as participants who lost ≥1% of baseline body fat percentage), and non-responders (defined as participants with no change or <1% reduction in body fat percentage). Results: After 8 weeks of aerobic exercise training we did not find any significant changes in plasma vaspin concentration. Nevertheless, body weight and body fat percentage decreased significantly (P≤0.05) and plasma vaspin concentrations increased significantly (P≤0.05) in responders, but not in non-responders. Changes in plasma vaspin concentrations were significantly correlated with changes in plasma insulin and glucose levels, and insulin resistance index (HOMA-IR) only in non-responders. Conclusions: This study indicated that reduction in body fat percentage induced by aerobic exercise training could be an effective factor to increase plasma vaspin levels in sedentary overweight women.

Abstract
Aim: The purpose of this study was to investigate the effect of 4 week resistance training on plasma omentin-1 levels in Streptozotocin induced diabetic rats.
Method: In this experimental study 24 male Wistar rats with mean weight of 288±22g (mean±SD) were randomly divided into 3 groups: non-diabetic control (n=8), diabetic control (n=8), and diabetic training (n=8). Diabetes was induced by a single intra-peritoneal injection of streptozotocin (STZ) at a dose of 55 mg/kg. The resistance training consisted of climbing a ladder carrying a load suspended from the tail (3 days/wk, for 4 wk). After 4-week body weight, plasma omentin-1, glucose, insulin, non-esterified fatty acids (NEFA) concentrations and lipid profiles were measured.
Results: After four weeks plasma omentin-1 levels in trained diabetic rats was higher when compared with diabetic control group, but it was not statistically significant. We did not find any significant difference in plasma glucose, insulin, NEFA and lipid profile levels between all groups. Body weights alteration in diabetic resistance trained rats were significantly lower compared with the diabetic control group.
Conclusion: The results of this study indicated that plasma levels of glucose, insulin, lipid profile and omentin-1 remained unchanged in diabetic rats due to 4 weeks resistance training. Short duration of training program appears to be an effective factor in the absence of significant changes in plasma omentin-1 levels.
