Abstract
Introduction: Hemorrhoid is a common disorder causing pain, and its standard treatment is Hemorrhoidetomy. Also, pain is a common problem after surgery and control of it prevents physiologic and psychiatric complications. Kegel exercise is one of the relaxing and none invasive methods for reduction of pain. In this study the effect of kegel exercise on pain relief post hemorrhoidetomy is investigated. Materials and Methods: This study is a single blind randomized clinical trial. Samples were patients admitted for hemorrhoidetomy to Shahid Sadooghi hospital of Yazd. They were randomly divided in two experiment and control groups (each group 30 persons). Before operation, Kegel exercise was educated to experiment group and after surgery pain range were recorded. Data was analyzed using descriptive and analythic statistics (t and Pearson correlaton tests). Results: Findings showed that the mean score of post surgery pain in the first 48 hours after operation in experimental group was 26.50±5.82 and in control group 31.26±5.94, that have meaningful difference (P=0.003). Regarding the amount of analgesics, the mean use of analgesics after surgery in experimental group was 18.9±14.83 and in control group 52.83±29.89 which has meaningful difference (P=0.00001). Type of analgesics in the two groups 18, 24 and 48 hours after surgery with p=0.04, p=0.04 and p=0.05, had significant difference. There were not any correlations between pain intensity and numbers of Kegel exercise. Conclusion: Based on results, Kegel exercise decreased post hemorrhoidetomy pain and using analgesic drugs was decreased in experimental group. Preoperative education of this method is useful in pain management postoperatively.

Abstract
Background: The purpose of this study was to determine the effect of L-carnitine supplementation on glucose and lactate concentrations, and aerobic capacity during sub-maximal exercise on ergometery cycle. Materials and Methods: In this double- blind clinical trail, 34 healthy noathlete male students at Saveh University were divided into experimental (L-carnitine usage) and placebo (lactose usage) groups and had one trial of cycling on ergometer (PWC170). This trial was done in two stages: 1) Exercise protocol without L-carnitine or placebo supplementation, 2) Exercise protocol with 3g L-carnitine (90 minute before exercise) and placebo supplementation in the experimental and placebo groups, respectively. Immediately after the physical exercise, blood sampling was taken for determining plasma glucose and lactate concentrations, and lactate dehydrogenase activity (LDH). Through polar telemetry rest and sub-maximal heart rate, and also, VO2max were measured. Results: L-carnitine supplementation had no influence on plasma glucose and lactate concentrations. Otherwise, rest and sub-maximal heart rate, VO2max and LDH activity were equal in pretest and posttests. All variables remained with no change in control group. Conclusion: Regarding the effect of L-carnitine usage on performance of endurance exercises, the findings are still vague and controversial. Our findings indicated that ingestion of 3g L-carnitine 90 minutes before exercise did not affect the dependent variables. Further investigation is required to determine the direct effect of such supplementations on substrate utilization, fat-carbohydrate metabolism and performance on exercise.

Abstract
Background: The aim of the present study was to determine the response of lung function indices to aerobic and anaerobic exercises in polluted air. Materials and Methods: In this quasi-experimental study, 20 healthy men were randomly divided into two equal groups experiment and control. The experiment group initially had one session of aerobic exercise and after a three-week break, received one session of anaerobic exercise on ergometer bicycle in polluted air. The control group did the same kind of exercise in healthy clean air. Lung function tests were run before, right after (the first post-test), and 24 hours after the exercises (the second post-test). Results: Aerobic exercise in unhealthy polluted air resulted in the significant reduction of FEV1, FVC, and FEF25-75% indices in the first and second post-tests. Following anaerobic exercises in polluted air, a significant decrease was observed in FVC and FEF25-75% indices in both the first and second post-tests. FEV1 and FEF25-75% indices in the first and second post-tests, and FEV1 and FVC indexes in the second post-tests underwent a remarkably greater reduction following aerobic exercise. Conclusion: While aerobic physical exercise in polluted air caused a reduction in the lung function indices (FEV1, FVC and FEF25-75%) in the first and second post-tests, it seemed that anaerobic exercises in polluted air induced a significantly smaller reduction in FEV1 and FEF25-75% in the first and second post tests, and FEV1/FVC in the second post test.

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
Arterial baroreceptors are located in the carotid and aortic arteries and play a pivotal role in rapid control of cardiovascular system. The purpose of this article is to review the effects of baroreceptors stimulation on heart rate at rest and during exercise and cerebral blood flow rate in young and middle aged male and female individuals. There is ample evidence indicating that the arterial baroreflex remains functional during exercise by readjustment which is in direct relation to the intensity of exercise. These adjustments might be done through somatosensory afferents from peripheral regions of the body, pathways obeying central command neurons, or vasopressin and oxytocin pathways that converge into the nucleus tractus solitarii (NTS). Cerebral blood flow autoregulation is a process by which cerebral blood flow is maintained at a fixed rate despite fluctuations in cerebral perfusion pressure. Similar to that in young individuals, this mechanism, despite fluctuations in baroreceptors sensitivity, stabilizes cerebral blood flow rate in a certain range in middle-aged individuals, although with aging the absolute cerebral blood flow rate decreases in both genders. In addition, it has also been shown that after termination of carotid baroreceptors stimulation, heart rate increases which is known as postvagal tachycardia (PVT). It seems that two components, adrenergic and non-adrenergic, are involved in PVT.

Abstract
Background: Peripheral neuropathy is a common complication associated with diabetes mellitus. It has been shown that oxidative stress is an important etiological factor in neuropathy which contributes to its development however, the exact pathophysiology underlying this complication is not fully understood. This study was designed to examine the effect of regular exercise and vitamin C administration on pain threshold in rats. Materials and Methods: In this experimental study, 36 male Wistar rats (220±10 g) were allocated to control and diabetic (control, vitamin C, exercise, and exercise+ vitamin C) groups. Diabetes was induced by the subcutaneous administration of streptozotocin (60 mg/kg). A week after the induction of diabetes, the rats were subjected to swimming training and vitamin C treatment for 8 weeks. At the end of weeks 3, 5, and 8, Tail-Flick test was done on the rats to assess pain threshold. Data were analyzed using SPSS software. Results: Diabetes significantly decreased pain threshold in the rats. Diabetes-induced hyperalgesia was significantly decreased by training and vitamin C. Concurrent effects of training and vitamin C on thermal pain threshold were significantly higher than each of them alone. Conclusion: Regular exercise together with vitamin C administration can be a proper method for preventing thermal hyperalgesia associated with diabetes. Therefore, they can be effective in the treatment and management of pain

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: Exercise can counteract the negative effects of stress, but variations in exercise protocols and intensities have generated different results. The purpose of this study was to investigate the effect of immobilization stress on cognitive performance and the moderating role of exercise.
Materials and Methods: In this experimental study, adult Albino-Wistar rats were randomly assigned to 5 groups. The animals underwent immobilization stress (2 hours per day×7 day), exercise (30 minutes per day×7 day), or no intervention. The rats were trained and tested using Morris water maze.
Results: The control group had better performance than the stress group in acquisition (p<0.01) and recall (p<0.05) in Morris water maze. There was not a significant difference between exercise-stress and control groups in water maze performance. Stress increased corticosterone levels (p<0.001), but exercise had a significant effect on decrement of corticosteron levels (p<0.001). Also, despite the absence of a significant difference between sham and exercise groups in the acquisition stage, the exercise group had a better performance in the recall stage (p<0.05).
Conclusion: Immobilization stress can impair acquisition and mild exercise has a protective effect against stress-induced negative effects. Corticosterone may be a major mediator in the protective effect of exercise against stress-induced cognitive impairment. In addition, the role of exercise in retrieval of past experiences is more prominent than their acquisition.

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: The purpose of the present study was to investigate the probable changes of HSP70 , liver enzymes & Cpk in professional athletes after a training season and participating in skating open world championship.
Materials and Methods: 10 elite female skaters were chosen. Eccentric exercise test were performed in three sections (24 hours before the beginning of the training, after six months of training (before participating in Skating World Championship) and 24 hours after the end of world championship). The training program consisted of 26 weeks of training, performed 5 times a week encompassing specialized skate trainings. Blood samples were taken before and after each eccentric exercise test.
Results: there was no significant change, in HSP70 concentration in response to eccentric exercise test, in pre exercise period (p>0.898). But, it illustrated a significant increase in after eccentric exercise test, in post exercise period (p<0.031). Moreover, in measuring down, it showed a significant increased in the amount of liver enzymes and Cpk after eccentric exercise test in second and third step compared to first step (p<0.05).
Conclusion: the results of the study illustrated that improving an athlete's physical fitness level during training season and matches leads to a significant increase in the protective level of the body (via the production of HSP70), depending also on the ability of the body of the individual in producing that protein. It can also be stated probably individual body fitness level, is an important factor in determining ALT, AST, ALP levels after performing eccentric exercise.

Abstract
Background: Balance is one of the basic needs for daily activities. It has an important role in static and dynamic activities. The purpose of this study is to evaluate the balance of people with peripheral neuropathy after 4-weeks of functional and balance exercise program.
Materials and methods: In this quasi-experimental study, 22 diabetic patients with diabetic peripheral neuropathy (experimental group, n=11 control group, n=11) with the mean age of 53.79 years, mean height of 163.41cm, and mean weight of 71.49 kg, were randomly selected. Berg and T.G.U.G tests were used to evaluate the balance of patients. 12 sessions of combined training (balance and functional training) were used as intervention program. A paired t-test was used for the differences of pre-post test and independent t-tests were used to compare the experimental and control groups.
Results: The paired sample t-test showed that training program has significant effect on functional and dynamic balance. The comparison between the two groups showed no significant deference between pre-functional balance tests and significant post-functional balance test after training program.
Conclusion: Patients with diabetic neuropathy may have an impaired balance. The most important reason is the damage of proprioceptive receptors as combined training (balance and functional training) may improve balance and blood circulation in this organ also putting extra load on the visual system, vestibular and proprioceptive stimulation system and improves balance. Hence, it can be recommended as exercises to improve balance.

Abstract
Background: Aging is associated with appetite decline, weight loss, reduced muscle mass and increased fat mass. Ghrelin and Obestatin are two peptides that effect appetite. According to importance of physical activity in energy balance and some body composition variables the aim of this study is investigate the amount of ghrelin, obestatin and some body composition variables and their relationship in athletes and non-athletes 50 -70 year old men.
Materials and Methods: This is an analytical study. Thirty athletes and thirty non-athletes 50-70 years old men took part in this research. Ghrelin, obestatin and some body composition variables include weight, muscle mass, fat mass, present boy fat and body mass index were measured.
Results: The result of this study showed that muscle mass significantly (p<0.01) and ghrelin insignificantly (p=0.16) were higher in athlete group. In addition percent body fat was lower in athletes group insignificantly (p=0.13). There was negative significant relationship between ghrelin and obestatin with muscle mass and positive significant relationship between ghrelin and obestatin with percent body fat in non-athletes group. There was strong relation between ghrelin and obestatin in both groups.
Conclusion: Regular participating in basketball training can increase muscle mass in 50-70 years old men. It seems that exercise training can delay aging effects on body composition by increasing some anabolic hormones such as ghrelin and growth hormone and it can change relationship between ghrelin, obestatin and some body composition variables.

Abstract
Background: Physical activity and overweight both changethe body homeostasis for this purpose, in this study effect of two models of high and moderate intensity aerobic exercises on the amount of Adiponectin and Resistin were compared inobese and overweight females.
Materials and Methods: In this experimental study, 15 obese and overweight female (Mean age: 22.93±0.54 years weight: 75.15±2.07 kg hight: 160.6±1.38 Cm BMI: 29.24±0.73kg.m-2) were randomly selected as sample. Subjects were placed into high (33 min exercise, 85-90% of max hearat rate) and moderate (41 min exercise, 50-70% of max hearat rate) intensity aerobic exercise groups. Exercises lasted three days a week for eight weeks with an equal volume of consumed energy. In order to analyze data, independent-t test and Repeated Measure analysis of variance were used at a significance level of p<0.05.
Results: The results indicate a significant increase in Adiponectin after eight weeks of high-intensity aerobic exercise compared to moderate-intensity exercise (p=0.02). A significant reduction in fat mass and percentage was observed after moderate intensity exercise (p=0.03), too. In Addition, moderate intensity exercise caused a considerable decrease in Resistin after eight weeks (p=0.06).
Conclusion: High-intensity exercise appears to provide necessary metabolic stress to enhance Adiponectin, even without weight and fat loss.

Abstract
Background: Heat shock proteins (HSP) can act as a cellular protection by facilitating reconstruction of denatured proteins. The aim of this study is evaluation of protective effects of glutamine consumption on HSP70 and cortisol response.
Materials and Methods: In this experimental study, 28 soccer players divided into 4 groups: control (n=7), supplement (n=7), exercise (n=7) and exercise supplement (n=7). Supplements (glutamine) and placebo (Dextrin) to a 0.5 gram per kg of body weight and volume of 5 ml per kg of body weight one hour prior to the exercise protocol was used. exercise protocol include a 3-stage 20-minute run at 80% of maximum heart rate and rest 5 minutes. Blood samples of basal (after 12-14 hour overnight fasting), post exercise, and 90 minutes after exercise were gathered and HSP70 of serum and cortisol were measured with Elisa and RIA respectively. Data were analyzed with multivariate repeated measures (MANOVA) at p&le0.05 level.
Results: There was significant difference in HSP70 amounts between supplement group and exercise supplement group compared to the control group (p&le0.09, p&le0.019) and also supplement group with exercise supplement group (p&le0.032). Also there was significant difference Between post exercise and 90 min after exercise stages compared to basal stage (p&le0.08, p&le0.06) and between post exercise and 90 min after exercise (p&le0.030). In cortisol amounts between basal and 90 min after exercise stages (p&le0.026) there was significant difference.
Conclusion: Glutamine sitimulate of HSP70 induction and combination of supplement with exercise has a great HSP70 response thus athletes who wish to compete or have intense exercise, glutamine consumption is recommended.

Abstract
Background: The current study aims to investigate the impact of high intensity interval training (HIIT) on serum levels of CK and LDH as the muscle damage indicators and on Gelatinase-A (MMP-2) serum levels as the tissae inflammatory marker among young sedentary girls.
Materials and Methods: For this quasi-experimental study, 14 sedentary female college students were selected and randomly divided into two groups including the exercise HIIT group (means and standard deviations of age: 21.28 ± 2.56 (years) weight:52.86 ±4.95 (kg) and height: 163.1±3.7 (cm)) and the control group (means and standard deviations of age: 20.25 ±7.50 (years) weight:52.64 ±3.67 (kg) and height: 162.4±4.5 (cm)). The experimental group performed six repetitions of one-minute runs at 90%- 95% of HRmax. The blood samples were collected before and 30 minutes after the exercise protocol. The serum CK, LDH and MMP-2 levels were measured using corresponding kits. The data were analyzed through the independent t-test at the significance level of 0.05 (p<0.05).
Results: After collecting and analyzing Data, the results showed that CK and LDH levels increased significantly after performing HIIT, while there was no significant change in MMP-2 due to the HIIT.
Conclusion: It can be concluded that the HIIT protocol will lead to an increase in some indicators of muscle damage such as CK, LDH, and that no significant changes could be observed for MMP-2 as the body's inflammation response.

Abstract
Background: Delayed muscular soreness after resistance exercises or eccentric trainings is probably because of muscle damage and injury. Nutrition by playing a crucial role in both protein synthesize and catabolism can influence the extent of muscle injury. The objective of this study was to assess the effect of single portion of Glutamine supplement consumption on injury indices of muscle after a session eccentric resistance exercise.
Materials and Methods: This study used a randomized, double blind design that consisted of 80 volvnteer non-athletic males (aged 22.2±2.2 years, height 175±5 cm, weight 71.64±9 kg, body mass index 23.2±2.2 kg/m2, and body fat 17.5±2.4%). A total of 40 participants were divided randomly into 2 groups, supplement group (receiving 0.1 g/kg Body weight/day Glutamine) and placebo group (receiving 0.1 g/kg Body weight/day Maltodextrin). Serum keratine kinase (CK) was determined by photometric method, muscle pain and knee joint range of motion were measured using, respectively, a standard scale of PAS and goniometer before, 24 and 48 hours after a resistance test involving knee flexion.
Results: Glutamine supplement consumption caused no significant differences in CK levels reduction in none of the measured times, but it reduced the muscle pain at the times of 24 and 48 hours in comparison with the placebo group. In addition, the knee joint range of motion was significantly improved at 24 hours after the test.
Conclusion: It seems that this dose of Glutamine supplementation can reduce the apparent signs apart from muscle injury indices reduction.
