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.

IntroductionEvidence showed that adhesion molecules and inflammatory factors play an important role in the pathogenesis of atherosclerosis.The purpose of this study was to evaluate the effect of eight weeks of continuous and periodic aerobic exercise on the serum level of C-reactive protein and some adhesive molecules in men with heart failure. Materials and MethodsIn this study, 42 middle-aged men with heart failure were purposeful and randomly divided into three equal groups(14 subjects): continuous aerobic exercise, periodic aerobic exercise and control groups. Continuous training(45-70% of Maximum Heart Rate) and periodic exercise (45-80% of MHR with 5-10 minutes rest between each period) were done for 8 weeks(three days a week). Before and after exercise, blood samples were taken from three groups, ELISA method was used. Data were analyzed using SPSS (20 version) at a significant level of P≤0.05. ResultsAfter eight weeks of training, the level of C-reactive protein, adhesion molecule -1 and vascular adhesion molecule -1 had a significant decrease in the two training groups(P ≤ 0.05). but no significant difference was observed in the control group. There was a significant difference between the levels of hs-CRP(P = 0.023) and VCAM-1(P = 0.0001) in all three groups, but there was not a significant difference in ICAM-1 level(P = 0.17).ConclusionAerobic exercise by decreasing the levels of hs-CRP and VCAM-1 may play an important role in the prevention and control of cardiovascular disease in men with heart failure.

Background: Aerobic exercise is the most popular sport activity in cardiac rehab center for increase aerobic ability and decrease in fat mass of cardiovascular disease , the aim of this study was to investigate the effect of eight weeks aerobic exercise on LXR gene expression and lipid profile in middle aged men after CABG.Materials and Methods: The subjects were 20 CABG middle aged male patient were randomly assigned into two group : control (N=10), and aerobic training (n = 10) groups. Exercise group performed aerobic exercises for 8 weeks with an intensity 60% to 80% of heart rate. 48 hours before exercise and 48 hours after the last training session, all subjects blood samples were taken and plasma and monocyte isolation were performed to measure the indices. Data analysis were performed by using t-test and independent t-test, and non-parametric Mann-Whitney and Wilcoxon tests were performed at a significant level of p≤0.05.Results: Significant increase in expression of LXR gene value and HDL and significant decrease in total cholestrole, apo A and B ratio, LDL,TGS in experimental group compared to the control group compared to the control group has seen.Conclusion: Improvement of lipid profiles levels and enhancing the expression of LXR gene after 8 weeks of aerobic exercises showed that Performing regular aerobic exercises as part of the cardiac rehabilitation can be effective in reducing the incidence of atherosclerosis and preventing recurrence of the patient.

Background & Objectives: Cardiac rehabilitation is the most important proceeding to reduce the effects of heart surgery and its effects on cardiovascular disease. Exercise training because of low cost and being attractive can be a motivation for patients with cardiac rehabilitation programs.Exercise has influence on blood cellular components, especially the number of white blood cells, metabolism, metabolites, peptides and different type of gene expression.The aim of this study was to examine the effect of aerobic training on monocytes gene expression ABCG5 in middle-aged men after heart bypass surgery. Materials & Methods: In this semi-experimental study, 20 middle-aged malepatient who had coronary artery bypass surgery, were subjected to the study and were randomly assigned into two groups: control (N=10) and aerobic training (N = 10) groups. Blood samples were taken from subjects before and after training sessions.Monocytes isolated by centrifugation and m-RNA purified by Real-Time PCR was performed.Data were analyzed by ANOVA with repeated measures (SPSS version 16). Results: Results showed that, as a result of exercise training, there was significant increase in mRNA expression of gene ABCG5 in the experimental group than control group. Conclusion: It seems that exercise training as part of the cardiac rehabilitation in patients undergoing coronary artery bypass grafting can improve the reverse cholesterol transport process in the patients by impressing the expression of genes involved in lipid metabolism.

Background and purpose: The specific preparatory activities may have different effects on various body systems which are not yet clear. The purpose of this study was to investigate the effects of a single session of specific preparatory activities on humoral immunity and white blood cell (WBC) immediately and 24 hours after exercise in elite rock climbing athletes. Methodology: Ten elite rock climbing athletes (age 23.3±2.2 years, height 173.6 ±4.8 cm, and weight 64.5±7.3 kg) took part in this quasi-experimental study. Subjects were asked to perform specific exercises for 95 minutes (10 minutes warm up, 75 minutes climbing with different degrees of severity, and 10 minutes cool down). Blood samples were taken before exercise, immediately after exercise, and 24 hours after exercise. Data were analyzed using paired sample Student’s t-test and general linear model (p
