Abstract
Background: Muscle mass is known to be a significant predictor of bone mineral density (BMD), and myostatin is a negative regulator of muscle growth. The aim of present study was investigate the effects of resistance training on bone mineral density and serum myostatin in healthy young men. Methods and Materials: In this clinical trial thirty young men were assigned to resistance training (n=15) and control (n=15) groups. The training group participated in 6 mounths of progressive whole-body resistance training. Total body fat, lean body mass, total body BMD, femoral neck BMD and L2-L4 spine BMD were determined by Dual-Energy X-ray Absorptiometry (DEXA) before and after 6 mounths of resistance training. Serum level myostatin measured by enzyme immnoassay. Results: Resistance training caused significant increases in chest press (52.36±6.36 vs 62.20±8.96 kg), leg press (135.24±13.77 vs 146.91±17.66 kg), lean body mass (61.00±0.96 vs 62.58±2.08 kg) and femoral neck BMD (1.115±0.078 vs 1.131±0.088 g/cm2), whereas myostatin were decreased (102.91±10.18 vs 94.03±13.93 ng/ml) (P<0.05). Total body BMD and L2-L4 spine BMD did not change with 6 months resistance training. Conclusion: A 6 month resistance training program increases muscle mass, power and improves BMD of the femoral neck in young men, and myostatin inhibition may play an important role in increasing BMD which is induced by resistance training.

Abstract
Background: Adiponectin is a protein which is initially secreted exclusively by adipocytes but its secretion decreases in obese and overweight individuals. With its anti-inflammatory properties, adiponectin acts as an agent which can decrease the risk of type II diabetes and cardiovascular diseases. The aim of this study was to determine adiponectin serum levels in type II diabetic men and explore its relationship with insulin resistance following aerobic exercise.
Materials and Methods: In this semi- experimental study, 30 men with type II diabetes were randomly assigned to training and control groups. The training group went through an 8-week training program which consisted of three 40-50 minute aerobic exercise sessions a week (running on treadmill at intensities corresponding to 30to 75% of maximal heart rate (35-75% HR max)). For measuring adiponectin and insulin serum levels, blood samples were obtained through ELISA technique in 2 stages, weeks zero and eight. For determining insulin resistance, insulin resistance index was utilized. In order to evaluate the results, dependent and independent t-tests and Pearson correlation coefficient were used.
Results: The results did not indicate the presence of a significant relationship between adiponectin and insulin resistance following training (P=0, r=-0.14). In comparison with the control group, training induced a 39% decrease in adiponectin serum levels, a 10% decrease in BMI and bodyweight, and a 48% decrease in insulin resistance (P>0.001)
Conclusions: The findings of this study showed that in response to the 8-week aerobic training program, adiponectin serum levels significantly increased while insulin resistance got decreased. In addition, there was not a significant relationship between adiponectin serum level changes following training and insulin resistance index.

Abstract
Background: Old, obese, and sedentary individuals are at risk for diabetes and cardiovascular diseases. Exercise improves metabolic anomalies associated with such diseases, but the effects of caloric restriction in coupled with exercise on such high- risk groups are not known. The aim of this study was to evaluate the effects of a 12 week lifestyle modification program on C- reactive protein and metabolic syndrome parameters in middle-aged obese/overweight men.
Materials and Methods: In this experimental study with pretest – posttest design, 21 sedentary men were randomly assigned to 12- week caloric restriction (CR) [~500kcal] (age: 45.59± 4.90, BMI: 30.02± 1.73, CR, n=10) or exercise+caloric restriction group (EX+CR) [~500kcal] (age: 45.23± 5.6, BMI: 29.84± 1.60, EX+CR, n=11). Body composition, cardiovascular risk markers, and C- reactive protein were measured pre and post intervention.
Results: After 12 weeks of intervention, significant reduction in body weight, abdominal fat (visceral, subcutaneous), insulin resistance, blood lipid profile, and C- reactive protein were observed in EX+CR group (P>0.05), Whereas, in CR group only significant improvement were observed in body weight and insulin resistance index (P>0.05).
Conclusion: Lifestyle interventions incorporating diet to exercise improve insulin resistance, systemic inflammation, and other cardiovascular risk factors in middle-aged obese/overweight men.

Abstract
Background: Physiological studies suggest that sleep deprivation may influence bodyweight through affecting appetite (decreasing leptin and increasing ghrelin). The aim of this study was to evaluate the effects of 12 weeks of aerobic training on obesity indices, serum levels of ghrelin and leptin, and sleep quality in overweight and obese men.
Materials and Methods: In this quasi-experimental study, 22 overweight and obese men with low sleep quality were randomly assigned to aerobic training (n=12) and control (n=10) groups. Aerobic training was performed (50-60 min/day, 3 day/week) for 12 weeks. Serum ghrelin and leptin and obesity and sleep quality indices were measured before and after the intervention. Changes in dependent variables resulting from the training intervention were assessed by dependant t-test using SPSS software.
Results: After aerobic training, weight (p<0.03), body mass index (p<0.04), visceral fat (p<0.04), total abdominal fat (p<0.03), and sleep quality (p<0.001) significantly improved. However, ghrelin and leptin serum levels did not change in response to aerobic training (p<0.05) during the same period.
Conclusion: Short-term aerobic training improved obesity indices and sleep quality in obese/overweight men, yet this improvement was not accompanied by changes in ghrelin and leptin serum levels.

Abstract
Background: Anti-mullerian hormone (AMH) is a reliable marker for ovarian reserve and fertility capacity. The aim of this study was to investigate the differences in AMH between physically active and non-active women.
Materials and Methods: Eighty two reproductive age women (18-50 years) participated (42 active and 40 non-active) in this cross-sectional study. Physical activity level was estimated via the International Physical Activity Questionnaire. Information on fertility parameters were obtained from medical records. Serum AMH was measured using ELISA assay.
Results: There was not a significant difference in mean age between the two groups (P>0.05). There was a significant difference between physically active and non-active women regarding basal concentration of serum exercise AMH (3.90±0.75 ng/ml versus 1.63±0.53 ng/ml, respectively) (P<0.03). Abortion rates differed significantly (P<0.05) between physically active (0.13±0.26) and non-active women (0.40±0.51).
Conclusion: These findings indicated that physical activity may improve fertility capacity in healthy women by maintaining AMH.

Abstract
Background: There are few studies related to effects of exercise training, including concurrent training, on hormonal changes in children. Hence, the aim of this study was to Compare theeffects of 6 weeks of resistance training and concurrent resistance and endurance training on aerobic power (VO2peak) and resting levels of growth hormone and cortisol in healthy children.
Materials and Methods: The subjects ofthis quasi-experimental study were 35 healthy boys between 9-11 years old, which were randomly divided into three groups of concurrent training (n=12), resistance training (n=11), control (n=12). Experimental groups were trained during 6 weeks 3 times a week.Control group were performed only their routine activities. VO2peak test was taken 48 hours before and after implementation of 6-weeks protocols and samples were selected from all subjects.Measurement of resting levels of GH and cortical was performed with ELISA method. For data analysis, one way ANOVA and paired t-test were used.
Results: The results showed that VO2peak and resting levels of GH increased significantly in concurrenttraining group (p=0.001, p=0.003, respectively). Resting level of cortisol in concurrent group was significantly lower than the other groups (p<0.05) and it was reducedsignificantlyin concurrent training and resistance training groups (p=0.001, p=0.036).
Conclusion: It seems a concurrent training period has greater benefits on VO2peak and resting levels of GH and cortical in children in comparison with resistance training.

Abstract
Background: Polycystic ovary syndrome (PCOS) is a complex hormonal disorder affecting the reproductive and metabolic systems. The aim of this study was to investigate the effect of 8-week pilates training on anti-mullerian hormone level and cardiometabolic parameters in women with polycystic ovary syndrome.
Materials and Methods: In this semi-experimental study with pretest–posttest design, twenty PCOS patients (aged 28.16±4.29 y) were randomly assigned to pilates training or non-exercising control groups. The training group took part in an eight-week progressive pilates exercise program, three times weekly while the control group were instructed to maintain their normal daily activities throughout the eight-week experimental period. Serum levels of anti-mullerian hormone, body composition and metabolic parameters were assessed before and after the training period.
Results: After an 8 week pilates training, insulin resistance index, total cholesterol, LDL- cholesterol, triglycerides and abdominal fat were significantly decreased (p<0.05). Furthermore, anti-mullerian hormone concentrations decreased significantly in response to pilates training (p<0.05).
Conclusion: These results suggest that pilates training can have beneficial effects on metabolic indices and ovarian reserve in women with polycystic ovary syndrome over a two-month period.

Abstract
Background: Cardiac troponin T and creatine kinase are used as biological markers for cardiomyocytes and its levels in serum are used as indicators of myocardial cell injury. The purpose of this study was to compare the effects of 3 different training protocols (runing, swimming, and pedaling training) on myocardial cell injury biomarkers in young girls.
Materials and Methods: In this semi-experimental study with pretest–posttest design, ten healthy young girls (aged 23.0±1.6 y) were selected in a convenience sampling way. The subjects performed three types of exercise in 7 days interval. Blood sample was assessed before and after the exercise sessions. Data were analyzed using t-test and analysis of variance.
Results: Our results indicated that creatin kinase increased significantly after three types of exercise (p<0.05). Running exercise led to greater increase in serum creatine kinase (p<0.05). Also, troponin T levels significantly were increased after three types of exercise (p<0.05), although no significant differences were observed between exercise types (p>0.05).
Conclusion: Our data suggest that intensive exercise is associated with cardiac damage in less trained girls and the type of exercise is determinants of the magnitude of myocardial injury biomarkers release.

Abstract
Background: Diabetes mellitus is associated with reductions in fertility indices. Resistance training, on the other hand, through reducing the adverse effects of diabetes, exerts a positive impact on diabetic individuals. The aim of the present study was to examine the effects of ten weeks of resistance training on serum levels of reproductive hormones and sperm parameters in Wistar rats with diabetes mellitus type 2.
Materials and Methods: In this experimental study, 36 Wistar rats with mean weight of 200±50 were randomly assigned to healthy control, diabetic control and diabetic training groups. The diabetic resistance training group received ten weeks of resistance training (climbing up the ladder) following the induction of diabetes. Twenty-four hours after the last training session, left epididymis of the rats was examined for studying sperm parameters and blood serum samples were examined for evaluating reproductive hormones. Data were analyzed using one-way ANOVA and Turkey’s Post Hoc test at 0.05%.
Results: Ten weeks of resistance training induced significant increases in serum testosterone and FSH levels in the resistance training group in comparison to the diabetic group (p<0.007).Resistance training did not have any significant effects on serum LH levels in the resistance training group compared to the diabetic control group. In addition, sperm parameters (sperm count, survival rate and motility) presented significant improvements compared to the diabetic group(p<0.05).
Conclusion: Resistance training can improve sperm parameters, including sperm count, survival rate and motility, through increasing serum testosterone, LH and FSH levels (reproductive hormones) in rats with diabetes mellitus type 2.

Abstract
Background: Physical exercise is an important and effective part of comprehensive care of seniors, which declines aging progression. Because of the importance of physical activity in cardiovascular diseases prevention this study intends to investigate the comparision of structural and functional characterictics of the heart between middle- aged montaineer men and non-athlete peers.
Materials and Methods: In this cross-sectional and descriptive–analytical study, 13 middle- aged montaineer (age: 54.5±2.0 y, body mass index: 25.59±2.4 kg/m2) who have continues mountain activities during previous 24 months for at least 2 sessions per week, each session lasted 120 minute, and 14 sedentary, healthy peers (age: 54.1±2.2 y, body mass index: 26.8±2.3 kg/m2) who were not currently experiencing any regular physical activity (at least 6 months), were selected. All subjects underwent standard two-dimensional and Doppler echocardiography at rest. Cardio respiratory fitness was assessed using Bruce test. T test was used to compare groups with α=0.05.
Results: The results showed that mountain activities significantly increased left ventricular mass (p=0.03) and left-ventricular-end-diastolic-diameter (p=0.04). We also observed that systolic blood pressure (p=0.04), ejection fraction (p=0.05), stroke volume (p=0.03) and cardio respiratory fitness (p=0.03) were significantly improved by mountain climbing. In some of parameters such as shortening fraction, interventicular septum and left ventricular posterior wall there were no significant differences between groups (p>0.05).
Conclusion: These results suggest that regular mountain sports activities can have beneficial effects on structural and functional characterictics of the heart in middle-aged men.

Abstract
Background and Aim Physical activity has multiple health benefits, but its association with fertility in women is still unknown. Considering the critical effects of lifestyle on reproductive health, this study aims to compare the physical activity and body composition of fertile and infertile women.
Methods & Materials This is a case-control study that was performed on 100 fertile and 100 infertile women aged 20-40 years referred to the infertility treatment centers in Arak, Iran. they completed self-reported questionnaires surveying sociodemographic characteristics and lifestyle, and the International Physical Activity Questionnaire (IPAQ) assessing physical activity and sedentary behavior. Anthropometric characteristics and body composition were also measured. Multiple logistic regression analysis was used to analyze the association of fertility with physical activity level, sedentary behavior, and body composition.
Ethical Considerations This study was approved by the Ethics Committee of the University of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1400.050).
Results The level of physical activity (P=0.001) was lower and the body mass index (P=0.03) was higher in infertile women than in fertile women. In women with moderate level of physical activity, the risk of infertility was lower (OR=4.42, 95% CI: 1.60-12.99, P=0.004). Women who spent the time sitting for more than 300 minutes a day were 2.07 times more likely to have fertility than women who were physically active (OR=2.07, 95% CI: 1.36-3.14, P=0.001).
Conclusion Low physical activity, sedentary lifestyle and obesity are independent risk factors of infertility. To prevent infertility, more attention should be paid to the lifestyle of women.

Abstract
Introduction: Physical activity is one of the important lifestyle factors that can have positive or negative effects on the reproductive system, and more research is needed to reflect the effect of inactivity on fertility in order to provide safe lifestyle recommendations to help couples achieve pregnancy is required. Therefore, this study was conducted with the aim of describing and comparing the physical activity status of fertile and infertile men in Arak city in 2022.
Methods: The present study is a case-control study that was conducted on 220 fertile and infertile men (22 to 40 years old) referred to Arak University Jihad infertility centers that were selected through available sampling. Participants completed self-test questionnaires on socio-demographic characteristics, lifestyle, physical activity, and sedentary behaviors. Anthropometric characteristics and body composition were also measured. Multivariate logistic regression was used to analyze the association of infertility with physical activity level, sedentary behavior, and body composition.
Ethical Considerations: This study was approved by the Ethics Committee of the University of Arak University (Code: IR.ARAKMU.REC.1401.046).
Ethical Considerations: The present research has been registered with the code IR.ARAKU.REC.1401.015 in the Ethics Committee of Arak University.
Results: In this study, it was observed that the amount of physical activity (P=0.02) and body composition (P=0.001) in fertile men is more favorable than infertile men. In men with a low level of physical activity, the risk of infertility increases 2.97 times (odds ratio 2.97 and 95% CI: 1.03, 8.61, and P=0.04). On the other hand, in men with moderate level of physical activity, the risk of infertility decreases (odds ratio 0.27 and 95% CI: 0.08, 0.92, and P=0.03). Also, in men who sit for more than 6 hours a day, the chance of infertility increases by 3.02 times (odds ratio 3.02 and 95% CI: 1.28, 7.10, and P=0.01). An increase in body mass index increases the risk of infertility by 1.61 times in men (odds ratio 1.61 and 95% CI: 1.23 and 2.11 and P=0.001).
Conclusions: Since obesity, physical inactivity and infertility in Iranian men are increasing at the same time, so there should be more focus and seriousness on the issue of lifestyle modification and especially physical activity regarding reproductive health.

Abstract
Introduction: In recent years, the use of X-rays in medicine and industry has expanded significantly. X-rays can cause oxidative stress and subsequently induce destructive effects on the kidneys. On the other hand, it has been proven that according to the theory of hormesis, resistance exercises have antioxidant effects, which may be used to reduce the harmful effects of X-rays. This study investigated the effect of resistance training on oxidative stress factors and structural changes in kidney tissue in rats exposed to X-rays
Methods: Twenty-four male rats were randomly divided into 4 groups. The irradiated groups were exposed to 4Gy X-ray. The training groups were exercised 5 times per week for 10 weeks. 24 hours after the last training session, blood samples were collected for evaluation of oxidative and antioxidant factors, and kidney tissue was isolated for stereological studies. The data was analyzed by one-way ANOVA in SPSS 20 software.
Results: In this study, whole-body X-ray irradiation caused a significant increase in kidney volume (P=0.003), cortex volume (P=0.02), glomerular volume (P=0.039), and serum Malondialdehyde (MDA) level (P=0.03). Also, performing the training protocol significantly reduced kidney volume (P=0.03), cortex volume (P=0.04), glomerular volume (P=0.033), and serum MDA level (P=0.02).
Conclusions: Based on this research, it seems that resistance training can lead to a decrease in glomerular filtration by creating adaptation and increasing antioxidant defense and changes in the hemodynamics of the kidneys, and as a result, reducing the volume and number of glomeruli, reducing the volume of the cortex and kidney, and it can improve the structure of kidney tissue in rats exposed to X-ray radiation.
