Therefore, the aim of the present study was to investigate the effect of an intense resistance session with glutamine on Myogenin and Myosin creatine kinase gene expression in male Wistar rats. Materials & Methods: 30 8-week-old male rats with an approximate weight of 220±20 were prepared and divided into three groups, control, intense resistance training, and intense resistance training with glutamine, in a simple random manner. The training groups participated in a resistance session of climbing the ramp with 4 sets, 5 repetitions, 30 seconds of rest between repetitions and 2 minutes of rest between sets. Glutamine was once a day powder dissolved in 100 cc of distilled water at a dose of 5.5 grams per kilogram of body weight every day for 5 days. The Extensor Digitorum long muscle tissue was sent to the relevant laboratory to study the expression of Myogenin and Myosin creatine kinase genes. The relative fold change method was used to check gene expression data at a significance level of 5%. Results: The gene expression results showed that myogenin and myosin creatine kinase gene expression levels increased significantly as a result of a high-intensity resistance training session with glutamine compared to the control group, and this value was more pronounced in the resistance training group (p<0.05). Conclusion: It seems that an intense resistance training session is more effective than glutamine on the increase of myogenic genes. Manuscript profile -

The present study was designed to compare the effect of endurance, resistance and combined exercises on the level of adiponectin gene expression in the hand and leg muscles of Wistar rats. Materials & methods: The current study is an experimental research in which 40 healthy male Wistar rats were divided into four ten groups of control, resistance training, endurance and combined. Each group did their own exercises for 8 weeks. Finally, hand and foot muscles were examined to measure the adiponectin gene. Results: The results of the analyzes showed that the level of adiponectin gene expression was different among all groups (P < 0.001). The relative expression of adiponectin gene in all training groups increased significantly compared to the control group (P < 0.001).Also, comparing exercise groups together, combined exercises had the greatest effect and resistance exercise had the least effect. In intra-group comparison, adiponectin gene expression was higher in hand muscle than leg muscle during resistance training (P = 0.047), but gene expression was higher in leg muscle during endurance training (P = 0.029). These two muscles were not significantly different during combined training (P = 0.086). Conclusion: According to the results of this study, all types of sports training can increase the expression of adiponectin gene, but combined, endurance and resistance training have the greatest effect, respectively.

Post-operative exercise coronary artery bypass grafting (CABG), and its adaptations, increase skeletal and cardiac capillary density associated to developing new capillaries called angiogenesis and improve cardiovascular function and functional ability. This study aimed to investigate the effect of cardiac rehabilitation on HIF1- α gene expression in post-CABG coronary patients. The sample contained 30 men aged 45-60 years who underwent bypass surgery. They were randomly divided into experimental (n = 15) and control (n = 15) groups. The experimental group performed aerobic resistance training for eight weeks (3 sessions per week), and the control group did not. Blood samples were taken 48 hours before starting the first training session and 48 hours after the last training session, while all subjects were fasting. Independent and paired t-test and Shapirovilk test were used to analyze the data at a significant level of 0.05 in SPSS version 21. The results showed that the HIF-1α gene expression in the aerobic resistance group also increased in the control group which was statistically significant (p < /em> = 0.001) as well as before and after changes in the exercise group. The control group was significant (p < /em> = 0.001). Due to the findings of the present study, it can be concluded that combined (aerobic-resistance) exercises may increase cardiovascular function by increasing HIF1α-1 gene expression and the growth of new capillaries called angiogenesis and by increasing circulation. It improves patients' quality of life after CABG. Manuscript profile -

It is associated to the exercise activity and the expression of some genes involved in the blood cholesterol transmission. Adenosine triphosphate-dependent box protein 8 is a member of ABC transporter family which plays a key role in the metabolism of high-density lipoprotein cholesterol and cholesterol. This study aimed to evaluate the effect of eight weeks of aerobic resistance training on ABCG8 gene expression and lipid profile in CABG patients. 30 men with CABG patients voluntarily selected and randomly divided into the experimental (n = 15) and control (n = 15) groups. The experimental group performed the aerobic resistance training for eight weeks (3 sessions per week) and the control group did not. Blood samples were taken 48 h before the first training session and 48 h after the last training session, while all subjects were fasting. Independent and paired t-test used to analyze the data at a significant level of 0.05. The present study's results showed that the aerobic resistance training group showed a significant increase in the ABCG8 mRNA expression and a significant decrease in LDL-C, triglyceride, and HDL-C as compared to the control group. Due to the findings of present study, it can be concluded that aerobic resistance training by increasing ABCG8 gene expression has a great effect on increasing the cholesterol transfer process; thus, it may improve the CABG patients and prevent cardiovascular diseases.

Therefore, this study was aimed at investigating the effect of 12 weeks of circuit resistance training with three different intensities of equal volume on some hemodynamic factors on obese men. Forty four obese men aged 23 to 33 years (BMI≥30, (WHtR)> 0.5) in four control groups: low-intensity circuit resistance training (40% Rm1), medium (60% Rm1) and high (Rm1) 80% (11 = number in each group) with equal volume. Before and after 12 weeks of resting heart rate training, resting systolic and diastolic blood pressure and pressure product rate were measured. Two-way analysis of variance (ANOVA) and Bonferroni post hoc test were used to examine the intragroup changes using t-test and comparison of groups (P≤0.05). It seems that 12 weeks of circuit resistance training has a positive effect on lowering blood pressure and pressure product rate besides improving indicators related to heart function. High-intensity exercise is likely to have a greater effect on resting heart rate, systolic and diastolic blood pressure, and double heart rate. Manuscript profile -

In this semi-experimental research with a pre-test-post-test design, 20 female athletes were randomly divided into 2 groups of 10: resistance training group with BCAA supplementation and resistance training group with placebo supplementation, one in the morning and one in the evening. A bout of resistance activity including 10 sets of eight repetitions of squats with 70% of 1RM using the Smith machine and a 3-minute rest between each set was performed by all participants. After completing the squat protocol, participants performed five consecutive sets of 20 repetitions (10 repetitions of split body weight jumps) with two minutes of rest between each set. The obtained data were analyzed using the dependent t-test and the covariance test with Benferroni's post hoc test using spss version 22 software. The results of the study showed that the serum levels of creatine kinase and the amount of delayed muscle pain and stiffness immediately, 24 and 48 hours and the serum levels of interleukin 6 immediately after intense resistance activity increased significantly compared to the baseline state. Also, the plasma levels of creatine kinase and the level of delayed muscle pain and stiffness in 24 hours and the level of interleukin-6 plasma levels have reached their peak after intense resistance activity, and this level was significantly higher than 48 and 72 hours after intense resistance activity. The present study showed that the consumption of BCAA supplement (0.22 g/kg) before and after exercise has no beneficial effect in reducing injury, muscle pain and inflammation in resistance trained women after senteric resistance training.
