Abstract
Introduction and Purpose: Due to the importance of functional balance tests assessment with emphasis on
parameters influencing the balance including somatotype, this study undertaken to determine the reliability of
functional balance tests (static, semi-dynamic and dynamic) in endomorphe healthy women within 24-34 years
old. Methodology: 25 female endomorphe with the average and standard deviation age of 27.32±2.13 yrs,
height of 161.13±6.37 cm and weight of 58.28±8.46 kg, participated in this study. Functional balance tests
were assessed while Heath-Carter approach applied to determine the participant somatotype. All the functional
balance tests are used for each individual three times within 72 hours. Data distribution normalization are
evaluated by means of Kolmogorov-Smirnov test, while ICC was used for assessing the reliability at a
significance level of P<0.05. Results:The reliability of all static, semi-dynamic and dynamic balance tests used
in this study was confirmed with an endomorphe type body. Assessing static balance, the Stork and Angel
tests; semi-dynamic balance, Star Excursion Balance Test test; and dynamic balance, the Timed to Get Up
and Go and Tandem Walking tests got very good reliability level (ICC>0.80

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 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
Using appropriate devices and scientific methods can accelerate the process of sport talent identification and development to achieve championship level, and could also provide condition in which capable and talented athletes obtain highest level performance rapidly, so they will have long life championship. Former researches in scope of sport talent identification usually have been done in order to determine or normalize effective parameters. The purpose of this study was to design football talent identification algorithm based on fuzzy logic which classifies the football athletes. Due to expert opinion, essential parameters of football talent identification which also used in this software are; Cardio respiratory capacity (Physiology), Agility (Ability of motion), Dribble (technical skill) and Motivation (psychology). Norms of elite football player teenagers (14-16 yrs) are also used as index. Then with considering parameters and index, a fuzzy algorithm is designed which classifies football players in Unmatched, Semi-matched, Matched, Brilliant and Rare class. These results can help trainers and coaches in order to select talented and capable football players. In validation and reliability, records of elite junior Brazilian and Portuguese soccer have compared with norms of Iranian elite soccer.

Abstract
Using appropriate devices and scientific methods by coaches and trainers can accelerate the process of sport talent identification and development, and could also provide condition in which capable athletes to be directed in to suitable sport according to their abilities and skills. Former researches in scope of sport talent identification usually have been done in order to determine or normalize effective parameters. The purpose of this study was to design volleyball talent identification algorithm based on fuzzy logic which ranks the volleyball athletes. Due to expert opinion, essential parameters of volleyball talent identification which also used in this software are; Height (Anthropometry), Velocity (Ability of motion), Vertical jump with run-up (technical skill) and Pair jump (functional skill). Norms of young elite volleyball players are also used as index. Then with considering parameters and index, a fuzzy algorithm is designed which classifies volleyball players in Unmatched, Semi-matched, Matched, Brilliant and Rare class. These results can help trainers and coaches in order to select talented and capable volleyball players.
