Coronary artery bypass graft (CABG) is a surgical procedure used to treat coronary heart disease. The present study aimed to investigate effects of 8 weeks of combined rehabilitation training on plasma levels of leptin, adiponectin, and resistin in middle-aged men who have undergone CABG.

The present research was a quasi-experimental study with a pretest-posttest design. The statistical population included all patients who have undergone CABG in Mashhad, Iran. Overall, 26 middle-aged men who have undergone CABG were enrolled in the study. The subjects were divided into a training group (n=14) and a control group (n=12). Data were analyzed in SPSS software (version 21) using analysis of covariance and paired t-test at significance level of 0.05.

Plasma levels of leptin did not change significantly (p=0.709), adiponectin increased significantly (p=0.001), and resistin decreased significantly (p=0.005) after the training intervention.

As a non-pharmacological intervention, the rehabilitation training has cardioprotective effects on patients who undergone CABG.

Cardiovascular diseases are one of the leading causes of death in the world. The aim of the present study was to evaluate the effect of eight weeks of combined exercise on adiponectin and resistin levels in middle-aged men after coronary artery bypass grafting.Method and Materials: The research method was quasi-experimental and pre-test with post-test. The statistical population was all patients with coronary artery bypass grafting in Mashhad. In the present study, a research sample consisting of 26 middle-aged men after coronary artery bypass graft surgery was divided into experimental (14) and control (12) groups according to the inclusion criteria. Data were analyzed using paired t-test and correlated t-test at the significance level of P≥0.05.

The results of paired t-test showed that adiponectin levels in the combination group increased significantly after eight weeks of combination training (P = 0.001), but decreased significantly in the control group (P = 0.577). Also, the results of independent t-test showed that adiponectin levels in the combined exercise group were significantly higher than the control group (P = 0.0001). Also, in relation to the resistin index, the results of the correlation test showed that the levels of this index in the combined training group decreased significantly after eight weeks of training protocol (P = 0.005). But in the control group, a non-significant increase was observed (P = 0.720). Also, the results of independent test showed that the resistance levels of the combined exercise group were significantly reduced compared to the control group (P = 0.006)

The present study showed that combination exercises because positive changes in cardiovascular factors and can be used as a non-pharmacological method to treat these diseases.

Atherosclerotic cardiovascular disease is the leading cause of death in industrialized countries. High level of plasma lipids including cholesterol and triglycerides is one of the most important risk factors of atherosclerosis. Previous studies have shown that three members of the ATP-binding cassette, subfamily G (ABCG4, ABCG5 and ABCG8) are involved in transporting sterols across membranes. The purpose of this study was to assess the effect of high-intensity resistance training (HIRT) and aerobic exercise (AE) on expression of the ABCG4, ABCG5 and ABCG8 genes in female athletes.

Twenty-four female athletes from the Khorasan Province (Iran) were randomly selected and assigned into three groups: control (N=8), AE (N=8) and HIRT (N=8). The subjects in the HIRT group and the AE group performed exercise at intensity of 75-80% of 1-repetion maximum and 75-80% of maximum heart rate, respectively. Blood samples were collected at baseline and immediately after the exercise session. After isolation of lymphocytes by centrifugation and purification of mRNA, gene expression changes were investigated by Real-Time-PCR. Data were analyzed using one-way ANOVA and the Tukey's test.

Both training protocols significantly increased the expression of ABCG4, ABCG5 and ABCG8 in the subjects (P<0.05), and there was no significant difference in the expression of these genes between the experimental groups (P>0.05).

A single session of HIRT and AE may have beneficial effects on prevention of atherosclerosis.
