Background & Aims: Physical activity by modulating angiogenesis in adipose tissue, effects on the entire body metabolic profile. Therefore, the aim of this study was to investigate the effect of 12 weeks of moderate intensity continuous training on VEGF, PEDF and PAI-1 of visceral and subcutaneous adipose tissue in obese rats.
Materials & Methods: 15 male Wistar rats were divided into 2 groups of high fat diet (n= 10) and rat fed with standard food (n=5). After 12 weeks, the high-fat diet group again divided into 2 MICT and control high-fat diet groups. The training program was performed for 12 weeks, 5 sessions per week, with a speed of 60-50% of maximum speed. VEGF, PEDF and PAI-1 levels of subcutaneous and visceral fat were measured by ELISA method. Data were analyzed by independent t-test and one-way ANOVA (P≤0.05).
Results: 12 weeks of high-fat diet significantly increased and 12 weeks of MICT significantly decreased the weight of the rats. The levels of subcutaneous and visceral fat VEGF in the MICT group were significantly higher than the control high-fat diet group (P= 0.008). PEDF values of subcutaneous fat (P= 0.001) and PAI-1 values of visceral fat (P= 0.002) in the MICT group were significantly lower than the control high-fat diet group.
Conclusion: Moderate-intensity continuous training improves the angiogenesis disorders due to adipose tissue hypertrophy; especially visceral adipose tissue that secretes inflammatory factors. This action has a significant role in controlling the metabolic disorder of obesity.

Background & Aims: Exercise with modulation of hepatokine counteracts pathological abnormalities of the liver due to fat accumulation. Therefore, the purpose of this study was to investigate the effect of high-intensity continuous training (HICT), high-intensity interval training (HIIT), and moderate-intensity continuous training (MICT) on Fetuin-A, FGF-21 and liver enzymes of the obese rats with high-fat diet.
Materials & Methods: A total of 25 male Wistar rats were divided into 5 groups: 1) healthy control; 2) high-Fat Diet (HFD) control; 3) HICT; 4) HIIT and 5) MICT. Except for the healthy control group, all rats were subjected to the high-fat diet for 12 weeks and then the training rats were trained for 12 weeks, 5 sessions a week. Fetuin-A and FGF-21 values were measured by the ELISA method. Data were analyzed by dependent t-test and one-way ANOVA at a significance level of P≤0.05.
Results: The results of the ANOVA test showed that there is a significant difference between groups in Fetuin-A (P = 0.001 and F=7.670) and FGF-21 (P= 0.010 and F=4.394). It was also found that different training modalities had a different effect on hepatokine (MICT: a significant reduce in Fetuin-A and HICT: a significant increase in FGF-21) and had the same effect on ALT and AST. The HFD control significantly increased liver enzymes (P= 0.001). However, all the exercise types significantly decreased these enzymes (for all groups, P= 0.001).
Conclusion: MICT exercises are more capable of controlling liver negative hepatokine such as Fetuin-A that prevent insulin resistance. However highintensity exercises such as HICT can increase the positive factors, such as FGF-21, that modifies the activity of the liver enzymes. As a result, it seems that obese subjects can use moderate to high-intensity exercises to prevent fatty liver.
