Abstract
Background: Postpartum women are a population at risk for sedentary life. Previous studies have shown that self-efficacy is an important determinant of stage of change and exercise adherence. This study evaluates the relationship between self-efficacy and stage of change and physical activity (PA) behavior in Iranian mothers. Materials and Methods: In this cross-sectional study, 300 postpartum mothers were selected randomly from all health centers in Arak. The instruments used in this study included the 7-day PA recall, stages of exercise adoption tool, and self-efficacy for exercise scale. Data analysis was performed using SPSS software. Results: Ninety-one percent of the participants were in the pre-contemplation, contemplation, and preparation stages of change. Mean score for moderate PA was 38.94±40.5 minutes a week. Significant relationships were found between the stages of PA behavior change and METs of weekly energy expenditure from moderate activities (r=0.60, P<0.001). Also, statistically significant relationships were found between self-efficacy and the stages of PA behavior change (r=0.50, P<0.001) weekly energy expenditure from moderate activities (r=0.40, P<0.001), and pre-pregnancy PA behavior (r=0.39, P<0.001). Conclusion: The level of PA of the participants was less than the recommended minimum level for regular PA behavior (150 minutes of moderately intense PA per week). In this population, self-efficacy plays an important role in PA behavior and it should be taken into consideration in designing interventions for improving PA behavior.

Abstract
Background: Epidemiological studies have shown the relationship between incidence of asthma symptoms and environmental factors, such as sedentary lifestyle and metabolic and cardiovascular diseases. However, the role of exercise rehabilitation protocols on lung function in obese adult patients with chronic asthma is a controversial issue. The aim of the present study is to evaluate the impact of aerobic exercise on lung function in obese middle-aged men with chronic asthma. Materials and Methods: This semi-experimental study was conducted on 39 obese middle-aged males with mild and moderate asthma. The experimental group (n=19) with regard to the safe range 15≥ RPE>9 followed the sub-maximal rehabilitation exercise program (50 to 80% HRmax intensity) for 3 months. Then, they underwent one month of detraining. The control group (n=20) did not have any form of aerobic exercise. Spirometric parameters in base, three months of training, and one month of detraining were measured by standard methods. Results: Indicators of lung function, including FVC, FEV1/FVC, PEF, FEF%75, and MVV significantly decreased. The pattern of changes in FEV1, FEV1/FVC, and MVV remained stable even after a month of detraining (p<0.05). However, no significant changes occurred in the dependent variables of the control group (p>0.05). Conclusion: It seems that the incidence of physiological adaptations of aerobic exercise, as a non-pharmacologic clinical factor, after the one-month detraining period affected the spirometric parameters in obese asthmatic patients

Abstract
Background: Due to high risk of physical inactivity in children with autism spectrum disorders (ASD) and its adverse consequences, evaluating their level of physical activity (PA) using accelerometry and investigating its relation with age and severity of the disorder are integral.
Materials and Methods: Fifty two boys and sixteen girls aged 7-14 years -from autism schools in Tehran- participated in current cross sectional study. Level of daily PA was evaluated for seven consecutive days using accelerometers. Autism severity was also assessed in the areas of communication, sociability, sensory and cognitive awareness, and health and physical behavior using Autism Treatment Evaluation Checklist (ATEC).
Results: On the whole 91 percent of participants encountered low level of PA. Girls were remarkably less active than boys and were more inactive. Level of PA significantly reduced as they aged. Level of PA was adversely and significantly correlated with autism severity in the area of sensory and cognitive awareness. Moreover, level of vigorous PA was adversely and significantly correlated with total autism severity. Finally, age, sex, and sensory and cognitive awareness were partially predictors of PA.
Conclusion: It appears that children with HFA are physically inactive and considerably engage in more sedentary activities as they age. Age and gender can be considered as physical activity determinants among this population.

Abstract
Background: Obestatin and leptin are two important hormones in energy homeostasis that have been discovered in recent years. The purpose of this study was to investigate the effect of eight weeks of intense aerobic exercise on plasma levels of obestatin, leptin, insulin and growth hormones in male obese Sprague Dawley Rats.
Materials and Methods: In this exprimontal study 50 male rats, with the weight range of 20±320 were taken from the Animal Laboratory of Medical Sciences in Shiraz University, and were divided into two training groups: experimental and control. The exercise program consisted of 8 weeks of intense aerobic exercise, 5 sessions per week. The exercise started at a speed of 5 meters per minute and with a slope of zero degree for 15 minutes and the intensity progressively reached up to the speed of 25 m/m and the slope of 15 degrees for 75 minutes in the last week and ended. Blood samples were taken 24 hours after the last training session and were sent to the laboratory to measure the levels of obestatin, leptin, insulin and growth hormones. SPSS software and one-way analysis of variance (ANOVA) and Pearson correlation coefficient were used to assess the results.
Results: There was a significant reduction in plasma levels of obestatin (p=0.02), leptin (p=0.02), and insulin (p=0.03), while the results showed that no meaningful difference was observed in the amount of growth hormone between the control group and intense training group (p=0.07).
Conclusion: The results of the present study have shown that after sports activities leading to weight loss, the reduction of anti-hunger hormones (obestatin and leptin) is expected.

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: The aim of this study was to determine the effect of preconception endurance exercise training with voluntary exercise activity during pregnancy in mother mice on lipid profile in adult offsprings.
Materials and Methods: Twenty four C57BL/6 female mice were randomly divided into four subgroups: trained in preconception period and exercised during pregnancy (TE)(20.3±1.02g); trained in preconception periods but unexercised during pregnancy (TC)(21.58±0.4g); untrained in preconception periods but exercised during pregnancy (CE)(21.02±0.23g); untrained and unexercised (CC)(19.23±0.45g). Trained mice were subjected to a protocol of moderate endurance exercise training over a period of 4 weeks for 5 days before pregnancy. The fasting blood samples were collected from adult mice(8 weeks old) and serum levels of glucose and lipid profile were measured. Data were analyzed using two way ANOVA and Tukey’s post hoc test.
Results: The Glucose test results in offspring showed that there was a significant interaction between group and sex and group main effect (p<0.001) Glucose levels of male offspring were significantly lower in TC and TE groups. Results on LDL also showed that the sex main effect was significant (p<0.001), and LDL levels of male born to TE and TC dams lower than in female offspring.
Conclusion: Improving the mother's physical fitness by providing regular endurance training in the preconception period and maintaining it by exercise activty throughout pregnancy may have potential for eliciting positive changes in lipid profile of offspring, specially males.

Abstract
Background: The advantageous effects of the regular moderate physical activity (Exercise) on reproduction is widely accepted, but until now, the alterations of the expression of hypothalamic arcuate nuclei gene affecting on reproduction axis in response to this type of physical activity are not clear. Therefore, the goal of the present investigation was to study the effect of one –month regular moderate physical activity on neurokinin B gene expression and reproductive axis hormonal changes.
Materials and Methods: In the experimental study, fourteen adult male Wistar rats were randomly divided into control and one- month regular moderate exercise groups. After one - month physical activity (20m/min), the arcuate nucleus was isolated from brain and stored in -80 refrigerators for neurokinin B gene expression assay by Real-time PCR method. In addition, serum samples were taken to assess the corticosterone, luteinizing hormone and testosterone levels by ELISA method. Data were analyzed by Independent t-test in SPSS.
Results: Neurokinin-B gene expression level was lower in the group which received physical activity than the control group(p<0.05). Also, corticosterone serum concentration was decreased in the physical activity group(p<0.05). By contrast, the physical activity induced luteinizing hormone and Testosterone serum levels evaluation in exersice group compared with control group (p<0.05).
Conclusion: Regular moderate physical activity may improve male reproductive performance by reducing the corticosterone hormone level and decreasing neurokinin B expression.

Abstract
Background and Aim: Conventional post-operative rehabilitation programs focus on quadriceps strengthening and knee range of motion. However, hip muscle weakness is evident in patients with knee osteoarthritis. The present trial study aimed to investigate the effects of adding early hip muscle strengthening exercises to conventional rehabilitation programs on pain, Range of Motion (RoM), Quality of Life (QoL), and physical function in patients with unilateral Total Knee Arthroplasty (TKA).
Methods & Materials: The intervention was initiated from the second day after surgery and continued for 10 sessions, 3 times a week on 24 participants in the control and intervention groups. Both research groups received Transcutaneous Electrical Neural Stimulation (TENS) and Infra-Red (IR), followed by exercises. The control group performed knee extensor and flexor strengthening and RoM exercises. The intervention group conducted hip-strengthening exercises in addition. Outcome measures included pain, knee flexion, and extension RoM, and QoL using the 36-Item Short Form Survey (SF-36), Timed Up and Go (TUG) test, Step Test, Six-Minute Walk Test (6MWT), and Hip and Knee Muscle Strength test.
Ethical Considerations: This research was approved by the Research Ethics Committee of Iran University of Medical Sciences (IR.IUMS.REC.1396.9511340012) and it was registered in the Clinical Trial Registration Center (Code: IRCT 20150314021459N6).
Results: All outcome measures improved in both research groups. The improvement in the scores of pain (P=0.03), knee extension RoM (P=0.007), and TUG test (P=0.033) were significantly higher in the intervention group, compared to the control group. The strength of knee flexors (P=0.023), hip flexors (P=0.040), hip extensors (P=0.028), hip adductors (P=0.040), and hip external rotators (P=0.047) significantly improved higher in the intervention group.
Conclusion: According to the present research results, both treatment approaches were effective on patients with unilateral total knee arthroplasty. Considering the better result of some of the outcome measures in the intervention group, the addition of hip strengthening exercises to knee exercises can be useful.

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.
