Background and purpose:Irisin, which is released in response to physical activity, has recently been reported as the therapeutic target in metabolic disorders. The present study attempts to discover the effect of eight weeks’ resistance or endurance training on the irisin level in rats’ gastrocnemius and liver.Materials and methods:To this purpose,15 male rats were randomly assigned to three groups of 5: the resistance group, the endurance group, and the control group. For 8 weeks, the resistance group did the activities on the treadmill and the endurance group on a one-meter-long ladder with 85 steep, while the control group did not receive any training. 72 hours after their last training session, the subjects were anaesthetized and their liver and gastrocnemius were removed. A Shapiro-Wilk test was run to determine the normal distribution of data, and a one-way ANOVA and a Tukey test were applied to analyze the data(P ≥ 0.05).Results: The normal distribution having been approved via the Shapiro-Wilk test, the one-way ANOVA showed a significant difference in the irisin levels between the groups’ livers and gastrocnemii (P =0.001 and P -0.016, respectively). The Tukey test revealed a significant rise in the liver tissue of the resistance group and endurance group in comparison to the control group (P =0.001 and P =0.742, respectively).Conclusion:According to this study, both resistance and endurance training can help significantly increase the irisin level of both the liver and the gastrocnemius, indicating how physical activity can help in the prevention and treatment of metabolic illnesses.

Background and purpose: Fibronectin transmembrane type III domain-containing protein 5 (FNDC5) is a characteristic factor in distinguishing skeletal muscle cells. Since the productive effects of regular exercise are conveyed through the skeletal muscle, this study aims to compare the effects of progressive endurance and resistance training on FNDC5 gene expression in male rats’ gastrocnemius muscles.Materials and Methods: 15 male rats were randomly assigned to three equal groups of: control, endurance training and resistance training. The endurance group performed 8 weeks of training on the treadmill. The resistance group did their exercises for eight weeks on a three-session-per-week basis on a one-meter-high ladder with 85○ slope. All subjects were anesthetized 72 hours after the experiment finished and the gastrocnemius removed. The level of FNDC5 expression was measured through real-time PCR method and one-way ANOVA applied to analyze the data. Level of significance was set to P≥0.05.Results: One-way ANOVA showed a significant difference in FNDC5 expression among the groups (P=0.001, F=31.791). A subsequent Tukey test application showed FNDC5 gene expression of the gastrocnemius muscle was significantly higher in the resistance and endurance training groups than in the control group (P
