Abstract
Background: The purpose of this study was to compare the effect of eight weeks of resistance training with and without the use of aqueous extracts of barberry and saffron on serum levels of RBP4, glucose, insulin and insulin resistance in obese mice.
Methods: In this study, 80 mice with a mean weight of 41± 2 g were exposed to high fat diet for 10 weeks. Then, they were randomly assigned to 8 resistance training groups (10 n), resistance and saffron (10 n), saffron (10= n ), Resistance and barberry (n =10), barberry (n =10), saffron and barberry (10n =), resistance training with extract of saffron and barberry (10n =) and control group (n = 10). The resistance training program included raising the mice from the ladder with weight (three sets and 5 repetitions each) three times a week for 8 weeks. The consumption of saffron and barberry extracts was done at 0.08 for total weight of mice for 8 weeks. After 14 hours of fasting, the initial blood sample was taken at 5 ml of the left ventricle of the rats and RBP4, glucose, insulin and insulin resistance levels were measured. One-way analysis of variance was used to compare the data between groups. All calculations were considered at P≤0.05
Results: The results showed that there was a significant difference in the levels of RBP4 (P = 0.002), glucose (P = 0.03), insulin (P = 0.02), and insulin resistance (P= 0.004) There are different research groups.
Follow-up test results showed that RBP4 levels decreased in the resistance training group compared to the barberry and control groups. In saffron group, resistance to barberry and control group decreased. The saffron group also decreased compared to the saffron and barberry training groups.
Conclusion: The findings of this study emphasize the effect of resistance training, the use of saffron extract and barberry extract on reducing the metabolic effects of obesity by reducing RBP4 and reducing glucose, insulin and insulin resistance.

Abstract
Backgrund: Saffron petals contain flavonoid compounds, glycosides, and anthocyanins. Considering the trend of increasing the use of medicinal plants in modern medicine in order to treat some diseases, the upcoming experiment was designed to investigate the effectiveness of the hydroalcoholic extract of saffron petals and alkaline water in comparison with the commercial drug metformin on the blood glucose level of diabetic rats.
Methods: In this experiment, 28 male Wistar rats were divided into 4 groups. 1) Diabetic animals (negative control), 2) Diabetic animals that received 200 mg of dry saffron petal extract daily, 3) Diabetic animals that had free access to alkaline water, 4) Diabetic animals that received 100 mg/kg BW metformin daily. They did the duration of the experiment was considered to be 28 days. During this period, feed and water consumption will be measured and recorded on a daily basis and weight on a weekly basis. At the end of the experiment, blood biochemical indices were measured.
Results: Weight and blood triglycerides were not affected by experimental treatments. While the feed consumed, water consumed, insulin, glucose, cholesterol, HDL, LDL and liver enzymes were significantly affected by the experimental treatments.
Conclusion: According to the results, the use of alkaline water and saffron petal extract positively reduced the blood glucose of mice and also had significant effects on feed and water consumption, cholesterol, HDL and LDL of animals. However, the definitive confirmation of the results of this experiment requires more studies and investigations in this field.

Abstract
Background: The aim of this study was to investigate the effect of eight weeks of circuit resistance training and saffron supplement on visfatin serum levels and insulin resistance in overweight men.
Methods: In this semi-experimental study, 40 obese and overweight students were randomly divided into 4 groups: exercise, exercise+supplement, supplement and control (10 people in each group). The exercise groups performed circular resistance exercises for eight weeks and three sessions each week for 90 minutes in the evening. The supplement and exercise+supplement groups used saffron tablets with a dose of 30 mg per day as a supplement. Blood samples were collected in two phases of the pre-test and 48 hours after the last training session. The data were analyzed using covariance and paired t test at a significant level of P≤0.05.
Results: Correlated t results showed a significant decrease in visfatin and insulin resistance in the post-test of the training, training+supplement and supplement groups compared to the pre-test (P<0.05). The results of the analysis of covariance showed that visfatin increased and the insulin resistance index decreased significantly in the exercise, exercise+supplement and supplement groups compared to the control group (P<0.05).
Conclusion: It seems that eight weeks of circuit resistance training and the addition of saffron help on visfatin serum levels and insulin resistance can lead to the reduction of these two variables in overweight men. The saffron plant can play a protective role due to the presence of flavonoids and by stimulating the secretion of Visfatin.

Abstract
Background: The beneficial effects of saffron extract and resistance training on the improvement of some diabetes indices have been determined, but their combined effect on BDNF protein levels in rats with type 2 diabetes has not been investigated. Therefore, the aim of the present study was to investigate the effect of saffron extract consumption during resistance training on BDNF protein expression in the hippocampus of rats with type 2 diabetes.
Methods: In this experimental study, 30 adult male rats were randomly divided into five groups: control (C), diabetes (D), diabetes-resistance training (DT), diabetes-saffron extract (DS) and diabetes-saffron extract- resistance training (DTS). Resistance training performed five sessions/w for six weeks. Blood glucose levels and hippocampus BDNF protein levels were measured. To analyze the data, one-way ANOVA was used at the significance level of P< 0.05.
Results: Blood glucose levels of all experimental groups were significantly higher than C group (P= 0.001). Blood glucose levels in DT, DS and DTS groups were significantly lower than D group (P= 0.001). Also, the blood glucose levels of the DTS group were significantly lower than that of the DT group (P= 0.014). In addition, BDNF protein levels of all experimental groups were significantly lower than group C (P< 0.05). Also, BDNF protein levels of D, DT and DS groups were significantly lower than DTS group (P< 0.05). However, BDNF protein levels of D, DT and DS groups were not significantly different (P< 0.05).
Conclusion: Performing resistance training also consuming saffron extract alone and during resistance training reduces blood glucose levels in diabetic rats. However, consumption of saffron extract could increase BDNF protein levels only during resistance training. Therefore, for more efficiency, it is suggested to consume saffron extract during resistance training.
