Abstract
The fencing lunge is one of the most common and fundamental attacking moves in fencing. The aim of this study was to provide kinematical compare of upper extremity among elite female and male senior fencers when performing a lunge. Four female and four male members of Iran National Team were selected as research sample. The subjects were filmed when performing a complete lunge with a camera of 300 Hz sampling rate to record their reactions to a light stimulus. To analyze the collected data, mean, standard deviation and student's-t test at significance level of p≤0.05 were used. The results revealed that elite male fencers had significantly shorter reaction and movement time comparing with elite female fencers. No major differences in other kinematic parameters indicate that elite male and female fencers performed lunge in similar way. The final conclusion of this study is that the existing differences in time of lunge technique may suggest the need for alternative training strategies to prepare fencing athletes.

Abstract
Performing a mental exertion during an exercise increase fatigue indices and the amount of fatigue seems to depend on the type of mental exertion. So, the purpose of the present study is comparing the effects of performing types of mental exertion during cycling exercise on fatigue indicators. Methods: 10 cyclist men with average peak power output 236 ± 36 W invited for 5 different sessions. In the first session, anthropometric characteristics and of cycling peak power output (PPO) have determined. In the next four sessions, cycling for 45-min at 65% PPO on the cycle ergometer with (Stroop, AX-CPT and PVT) or without mental exertion. Rate of perceived exertion (RPE) and heart rate were recorded while cycling every 10 min and cortisol concentration was measured before and 30 min after exercise finished. Two-way repeated-measures ANOVAs were used to analyzing data. Results: Performing 45 minutes of Stroop mental exertion during cycling exercise increased RPE and cortisol concentration compared to cycling exercise alone (P˂0/05) but there is no differences between AX-CPT and PVT to cycling exercise alone. Conclusion: The results of the present study showed that performing Stroop mental exertion during the cycling exercise than cycling exercise alone increase more the fatigue indices.

Abstract
The aim of this research was to study the effect of warm up with two different type intensity on plasma antioxidant enzymes and damage indices of lipid, protein and DNA after intensive activity in non-athlete males. 12 non athlete students of kharazmi University participated in this study. Firist, subjects VO2peak were measured by Gas analyzer (Meta Max 3B) on the ergometer cycle with incremental test. Work rate in the low and high intensities of warm up were calculated for each subjects on the VO2peak chart Then subjects in the three sessions with 48 hours interval divided to three groups of warm up with low and high intensity and non-warm. In each session resting blood sampling collected then first group warm up with low intensity (45-50% VO2peak) for six minutes and then perform intensive activity The Second group performed warm up with high intensity (75-80% VO2peak) and then intensive activity and third group directly without warm up performed intensive activity. Blood sampling collected after two hours of the intensive activity. In other sessions group members were changed by cross design method. Using analysis of variance with repeated measuring and the LSD test for statistic analyze. The results showed a significant differences in MDA, carbonyl-protein 8-hydroxy-2-deoxy Guanosine and also antioxidant enzymes SOD, CAT and GPX companing to resting state. Main difference of MDA and SOD was not signifacnatly lower in the low intensity warm up state rather than other state. In the other variables non warm up state have lower value and intensity warm up state have higher value. Result of the study indicate that low intensity warm up can decreased lipid damage but not effected on the protein and DNA damage. Also, High intensity warm up can case increases all three type of damage. Therefore low intensity warm up in non-athlete males is better than the high intensity warm up.

Abstract
Since, sports activities are likely to be changes in various parameters of plantar pressure distribution during walking to create, This study compared patterns of plantar pressure distribution between right and left feet and their relationship with anthropometric parameters. 10 elite wrestler with the average and standard deviation of age: 23.6±3.33 yrs, height: 173.5±7.67 cm and mass: 83.3±21.8 kg voluntarily participated as subjects in this study. EMED-AT2 System for plantar pressure analysis, of parametric statistical methods paired t-test to compare parameters between the right and left leg and also of the Pearson methods for investigating correlation between variables was used. The only in the contact area parameter between the right leg and left at 4th mask significant differences were found (p≤0.05, ES=0.03). Also positive and significant correlation between height and mass with all the parameters were found (p≤0.01, p≤0.05) and in the heel area the correlation between maximum force in the right foot with height (medial heel r2=0.45 ; lateral heel r2=0.68) and weight (medial heel r2=0.56 ; lateral heel r2=0.8) and in the left foot with height (lateral heel r2=0.53) and weight (lateral heel r2=0.55) was reversed. (p≤0.05). Considering the lack of significant differences in plantar pressure parameters between the right and left foot, it could be argued, in wrestling foot demand function is the same. Also this research confirmed the results previous study indicating the absence of dominant leg in wrestling.

Abstract
The purpose of the current study was the effect of 8-week high intensity resistance training (the Split training method), on Testosterone, Cortisol and Testosterone/Cortisol serum level and its influence on muscle mass and development of muscle strength. 20 persons beginner in bodybuilding (body mass index: 23.80±2.25 kg/m2; age: 24.65±2.55 year) participated in this study. The subjects divided randomly into strength training (10 persons) and control groups (10 persons). Training program was designed according to the Split method with 85%-100% of 1RM for six times per weeks. The same strength and duration was applied for the control group based on the traditional training. Before and after training the thickness of Triceps muscle was measured with ultrasound in both groups. Resting blood samples were collected before and after training. The results showed, compared with traditional training, training with Split method increased muscle strength (p=0.01), muscle mass (p=0.001) and the Testosterone to Cortisol (T/C) ratio (p=0.02). Moreover, there were significant correlation between the maximum strength and hypertrophy(r=0/55, p=0/001) and between (T/C) and maximum strength (r=0/74, p=0/03). The results of this study shows that resistance training with high intensity (the Split Training Method) causes increase in anabolic stimulation and muscle mass which subsequently increases maximum strength.

Abstract
Overweight is one of the most important reasons for increasing the liver enzymes that causes liver and cardiovascular disease. The purpose of this research is to investigation the effects of 12weeks training on liver enzymes. Subjects of this research is 26 woman with BMI≥29 and average age Between 42 to 52, they divided to two main groups: experimental and control group n=13. 24 hours before training and 48 hours after sampling, body composition and oxygen maximum, were done for all of the subjects. Experimental group have done 12 weeks endurance training that contains 3 session between 40 to 80 percent of heart beat and duration of 15 to 30 min. Data was analyzed by using of covariance and T test,(a≤0./05),results showed that in experimental group there is significant increase in oxygen maximum (p=0/006) and significant decrease observed in BMI (p=0/001). But not observed significant change in ALT enzymes (p=0/493) and AST (p=0/403). Results showed that the impacts of 12 weeks endurance training on liver enzymes of those women was not significant because of not preparing of subjects, also high level of BMI in both groups are possible. Therefore, non significant increase of ALT exercise group be investigated, the longer half life of this enzyme is (40+12) hours. So, it seems that we need more than 48hours to recovery the enzyme.

Abstract
Urinary incontinence has an increasing process among aged women and its statistics in women in The Home for the Elderly is more than others. The purpose of this study is to investigate effect of 4 weeks Spinal Stabilization exercises on urinary incontinence of the elderly people. In this study, participants are elderly women from age of 50 to 70 years old (67±11kg and BMI of 27±4kg/m2), who were placed in two experimental and control groups (10 people in each group) for 4 weeks (3 sessions per week). Urinary incontinence of the participants was measured through ICIQ-OAB questionnaire in pretest and posttest steps. According to abnormal distribution of data, nonparametric tests are used such as Wilcoxon and U Mann Whitney tests to test intragroup and intergroup variations at the level of p≤0.05. Spinal stabilization exercises caused significant reduction of urinary incontinence in elderly women (p=0.001), so that the exercises can result in insignificant reduction of urinary frequency per day (p=0.083), significant reduction of urinary frequency per night (p=0.001), stress of fast use of WC (p=0.001) and leakage of urine (p=0.002). Moreover, intergroup investigations showed that experimental group has lower urinary incontinence than control group (p=0.01). Spinal stabilization exercises can result in reduction of urinary incontinence and its components through strengthening pelvic floor and abdominal muscles.

Abstract
The present study aimed to examine the effects of FIFA 11+ comprehensive warm-up program for referees on dynamic balance among male Iranian football referees and assistant referees. Fifty-two football referees and assistant referees who had no previous injury voluntarily participated in the present study. They were randomly assigned into an intervention group and a control one (26 participants each group). The intervention participants took part in a 17-week FIFA 11+ comprehensive warm-up program for referees while the control group performed their usual warm-up trainings during a half season. In order to estimate the dynamic balance of the referees in the pre-test and post-test, Y Balance Test was used. The collected data were analyzed using Descriptive statistics and ANOVA. The results of the present study indicated that the intervention and the control groups were significantly different in terms of dynamic balance in anterior and posteromedial directions and also the referees’ overall balance score before and after the study. However, no significant between them was observed in posteriolateral direction. According to the findings of the present study, it can be concluded that the FIFA 11+ comprehensive warm-up program for referees could improve the referees’ and the assistant referees’ dynamic balance.

Abstract
Introduction and purpose: Reaching movement is one of the common task for assessing learning mechanism and is daily task in human life, improvement in postural stability can influence the function of this task. In this term, the aim of current study was to compare constant (simple reaction time) and variable random practice (choice reaction time) on the improvement of anticipatory postural adjustment during reaching task in healthy people. Methodology: Sixteen right handed women with the mean age of (27.18±3.18) participated in this study. For measuring magnitude of anticipatory postural control, centre of pressure displacement and centre of pressure velocity were evaluated by using force plate before reaching movement. Results: The results of mixed variance analysis in significant level of p<0.05 showed that random variable practice increased cop displacement and velocity before reaching task, but this increase wasn’t significant in acquisition and retention tests. Discussion and Conclusion: Therefore according to the results of this study, random variable practice improved anticipatory postural adjustment. Based on these results, effect of this practice on anticipatory postural control can be considered in rehabilitation programs.

Abstract
Introduction and aim: Taping is a common method used by athletes to improve muscular function. The aim was to assess the immediate effect of femoral external rotational and abductoral taping on three-dimensional ground reaction force characteristics, their time to peak, impulse, displacement of center of pressure, vertical loading rate, and free moment during stance phase of running. Method: 24 healthy men (age: 24.6±2.5 years; mass: 74.8±6.2 kg; 177.1±7.9 cm) were included in the study. Ground reaction force data was recorded by a Kistler force platform (sampling rate: 1000 Hz). Paired sample t-test was used for statistical analysis. Results: Compared to without taping condition, taping significantly reduced the peak impact and peak active vertical ground reaction forces during stance phase of running (P≤0.05; low to moderate effect size). Taping application increased and decreased the vertical loading rate (19%, P=0.047, moderate effect size) and the peak free moment values (P≤0.001), respectively. The values of the anterior-posterior and vertical impulses during taping condition were greater than that of without taping condition (P≤0.001; low effect size). Conclusion: Femoral external rotational and abductoral taping could improve the values of free moment, but this is not the case in vertical loading rate during the stance phase of running.

Abstract
Introduction: The decorin is a myokine that modulates the growth and the development of the cancer cells through the interaction with TGF-β. The present study is aimed to evaluate the protective effects of 8 weeks interval aerobic exercise on the expression of decorin and TGF-β, and tumor volume in a typical animal of breast tumor. Materials and Methods: In a exprimental research, forty adult female Balb/c mices were randomly divided into four groups: control, tumor, exercise, and exercise with the tumor. The main exercise was performed four weeks before and after tumor with 50-70 percent of the maximum power of mices. The mices were cancerous by subcutaneous surgery with tumor of adenocarcinoma of mice breast in the tumor group and the exercise group with the tumor. Tumor growth was measured weekly. At the end of the study, tumor and soleus muscle were extracted by surgery. Real-Time PCR method was used to evaluate the expression of decorin and TGF-β and data were analyzed by t-test, one-way ANOVA and post-hoc methods with considering the significant level of p<0.05. Results: The tumor growth rate in tumor group was significantly higher than the exercise group with the tumor. A significant difference confirmed between four groups In the level of decorin expression in soleus muscle (F=12.30 , P=0.0023). The Post hoc test showed that 8 weeks of interval aerobic training significantly increased the expression of decorum gene in soleus muscle in two pairs of exercise group compared with control group and exercise group with tumor compared to tumor group (P=0.02). The expression of TGF-β in tumor tissue showed a significant reduction in exercise group with tumor compared with tumor group. Conclusion: Our results showed that interval aerobic training probably contributes to decreasing the growth of breast cancer cells by increasing the expression of decorin and decreasing the expression of TGF-β.

Abstract
The purpose of present study was to determine the effect of 8 weeks of resistance training on serumic myostatin, and Fibroblast Growth Factor-2 (FGF-2) level in male Wistar rats. 20 adult male wistar rats(150-250gr) were randomly divided into 2 groups [control group; n=10 (C), resistance training; n=10 (R)]. Resistance training was conducted for 8 weeks (5 session/week) on a special 1 meter height ladder (divided by 26 stairs) with loading of 30٪ of body weight (suspended from the tail) in the first week and increased to 200٪ of body weight in the last week. Training includes 3 sets of 4 reps with 3 minutes rest between sets. At the end of last week blood samples were taken from the rats and myostatin, TGF-β1 and FGF-2 was measured in three groups with the ELISA kit. At the end of the study ،the plasma levels of the myostatin decreased [71/82±19/62 mg/dl (R) ver. 105/86±17/49 mg/dl(C). (p≤0/001)], but the level of FGF-2 increased significantly in resistance training group [102/462±11/135mg/dl (R) ver. 86/96±12/606 mg/dl (C) (p=0/048)]. In contrast, the serum level of TGF-β was not statistically different between the two groups [153/48±54/09 mg/dl (R).160/62±32/85 mg/dl (C). (p=0/725)]. This study shows that 8 weeks of resistance training reduces serum levels myostatin and increased serum levels of FGF-2. These two factors cause activation or non-activation of satellite cells (Muscle stem cells that control muscle hypertrophy). However the nerve - muscle agents in the first 8 weeks of resistance training have the maximum participation on strength increases, but in this research we see affect the signals of satellite cells in the first 8 weeks of resistance training can change significantly. Also, although serum levels of TGF-β1 in the exercise group was significantly different from the control group, but the overall value of the exercise group had slightly reduced.

Abstract
Eotaxin, a pro-inflammatory Adipokine is secreted from adipose tissue, which its secretion increases in the obesity and cause neurodegeneration. BDNF is a neurological factor that interferes with cognitive function, fat and sugar metabolism, as well as the pathophysiology of obesity and metabolic syndrome in adulthood. The aim of this study was to investigate the Effect of Six Weeks of Interval Resistance Training on Eotaxin and Brain-Derived Neurotrophic Factor Serum Levels in Overweight young men. Twenty non-active students without regular exercise program from Kharazmi University were randomly selected and divided into two groups of training (n=10) and control (n=10). The training group performed Interval resistance Training for 6 weeks, 3 sessions per week and each session lasted 45 minutes. The training program included 7 moves with intensity of 30-40% of 1RM and velocity 2v for 10 seconds and rest intervals with intensity 30-40% 1RM and velocity v for 20 seconds. Blood samples were taken before and after 6 weeks of training to evaluate the serum Eotaxin and BDNF levels using the Sandwich ELISA. To analyze the data, the covariance test and Bonferron's post hoc test were used to compare the variables. The results of covariance analysis and Bonferroni test showed that 6 weeks of Interval resistance training caused a significant reduction in the weight (p=0.003), body mass index (p=0.004) Waist circumference (p=0.012) and fat percentage (p=0.001). Also, significant increase was observed in muscular endurance (p=0.001), serum BDNF levels in the training group compared to the control group (p=0.024), and serum Eotaxin levels in the training group decreased significantly (p=0.022). Correlation results showed a significant reverse relationship respectively between pre and post training Eotaxin and BDNF (p=0.015 r=-0.511, p=0.013 r=-0.586). Weight loss through six weeks of Interval Resistance training, which accompanied the loss of adipose tissue; resulted in a reduction in serum levels of Eotaxin and increased serum levels of BDNF.

Abstract
The aim of present study was comparison of advanced physical fitness profile between Olympic soccer team members of Iran according to playing position. 29 Invited soccer players to the 17th national Olympic soccer team of Iran dispatched to 17th Asian Olympics Games, Incheon 2014 )mean age of 20.39± 2.01 yrs(, divided into five group of goalkeepers, defenders, midfield players, wingers and attackers according to playing position participated in the study. Body composition parameters (including body mass index, body fat percentage), isokinetic force (peak torque, agonist/antagonist ratio, work fatigue, total work of extension and flexion), aerobic power by analysis of respiratory gases and anaerobic power and fatigue index by Wingate test were packaged for data collection. Descriptive statistics (i.e., mean ± standard deviation) and inferential statistics (i.e., one way ANOVA with Hopkins post hoc after subtracting data of pre- post) used for analysis data. While it was unbelievable the findings did not show any significant difference between five groups of present study. It seems that Olympic soccer team players of Iran has not prepared in a conditioning principle and based on playing position for participate in 17th Asian games. Moreover it supposed that national players spent most of the preparation periods & specific based conditioning workouts on their clubs, hence due to the short time of conditioning in the national camps trainings, players have not dispatched to the games with favorable preparation.
