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.

AbstractBackground and Objectives: This study aimed to determine the effectiveness of eight weeks of endurance training with ginger supplementation on CRP and TNF-α in young girls aged 20 to 30.Materials & Methods: In this semi-experimental study,32 young girls 20-30 years old were randomly assigned in four groups (control, supplement, practice and practice + supplement). The weight mean and standard deviation of participants were (61.17 ± 11.1) kilograms, and their body mass index were (23.45 ± 2.7). Training program was planned for eight weeks and three sessions per week. Each session consisted of 45 – 60 minutes with an intensity of 65-75 Vo2 max. The supplement and practice + supplement groups received daily one gram of ginger (Four 250 mg capsules) for 8 weeks. Blood samples were taken 48 hours after the last training session. The data were analyzed using Kolmogorov-Smirnov, Levene's Test, Covariance (ANCOVA) And Bonferroni and by SPSS 20.Findings: The findings showed that endurance training decreases significantly TNF-α in Young girls 20-30 years old (P

Reactive oxygen species (ROS) result in serious damage oxidation of proteins, lipids and genomic structures. Studies have shown that production of ROS increases during intensive exercise training. The aim of present study was to investigate the effect of two type sprint and endurance exercise trainings on 8-oxoguanine DNA glycosylase (OGG1) and hydroxy-2'-deoxyguanosine (8-OHdG) levels in the brain and liver of Wistar rats. 24 adult Albino Wistar rats were randomly divided into sedentary control, sprint exercise training, and endurance exercise training groups. Rats in sprint and endurance exercise training groups ran on treadmill for 6 weeks, 6 days per week, at 80 to 100 percent of maximal oxygen consumption. OGG1 and 8-OHdG levels were measured using sandwich ELISA assay. Data analyzed using one way ANOVA at P≤0.05 level. Results showed that both of sprint and endurance exercise trainings result in significant increase in OGG1 levels in brain and liver. Sprint exercise training resulted in greater increase in brain OGG1 than endurance exercise training. However, sprint and endurance exercise training had no significant effect on 8-OHdG levels in brain and liver tissues. OGG1 content correlated negatively with 8-OHdG levels. Collectively, sprint and endurance exercise trainings prevents from genomic structure through an increase in OGG1 contents.

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

Background & Objectives: According to benefits of psycho-physiological effects of aerobic exercise, the purpose of this study was to investigate the effects of eight-week moderate-intensity aerobic exercise training on menstrual cycle disorders and plasma levels of FSH and LH. Methods: In this study, 20 women with menstrual disorder randomly divided into two experimental and control groups. The experimental group submitted 8 weeks of moderate-intensity aerobic exercise, while the control group had no regular physical training. 24 hours before and after the period of exercise training, follicular phase blood samples of all subjects were taken to measure hormonal variables and then they responded to questionnaires to determine levels of menstrual disorders. Results: The research results revealed that, after 8-week training, pain at Visual Analgesic Scale in experimental group decreased significantly (p<0.05). In addition, plasma level of FSH and LH hormones significantly increased and decreased respectively (p<0.05). Conclusion: It can be concluded that, by regular endurance exercise of moderate intensity, Dysmenorrheal can be reduced, and these exercises can be used as a preventive treatment or therapy to help control Dysmenorrhea and menstrual disorders.
