The Effect of Eight Weeks Progressive Resistance and Endurance Training on Liver Tissue and Gastrocnemius Muscle’s Irisin levels in Male Rats
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.
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).
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).
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.
