Abstract
Considering the important role of the scapula in the glenohumeral joint movements, its position on the thorax can affect the function of the joint. Therefore, the purpose of this study was to investigate the predictive relationship of the strength and glenohumeral rotation range of motion (ROM) with scapular dyskinesis (SD) in female athletes with
overhead-throwing pattern. The present study was a descriptive-correlational research on 60 athletic female in volleyball, handball, basketball and badminton. The Lateral scapular slide test was used to examine SD. the dynamometer and goniometer were used to measure the strength and glenohumeral rotation ROM respectively. Data were analyzed using Spearman correlation and multiple regression tests. The correlation coefficients between SD and the glenohumeral internal rotation ROM (r=-0.734; p=0.000), the glenohumeral external rotation ROM (r=0.693; p=0.001), the glenohumeral internal rotation strength (r=0.674; p=0.005) and the glenohumeral external rotation strength (r=-0.719; p=0.001) were significant. Analysis of the research model showed that about one-third (30.1%) of total changes in SD were dependent on the independent variables mentioned in this regression model. therefore, screening of athletes with overhead-throwing pattern must be taken into consideration in order to recognize SD, and participate in corrective exercises to increase the glenohumeral internal rotation ROM and the glenohumeral external rotator muscles strength.

Abstract
Knowledge of the relationship between performance and range of motion, helping to design training programs, comply of individual with the needs of children is, therefore, The aim of research the relationship between some of the lower extremity range of motion and biomechanical parameters of the boys was performed. Hundred students in this study were randomly selected. After measuring the range of motion of lower extremity, test speed, power, balance and agility of the subjects were recorded. By descriptive statistics to determine the mean and standard deviation of the method of multiple correlations to assess the relationship between the selected range of motion and biomechanical parameters of subjects were used. Hip flexion by speed, hip abduction and knee flexion by balance and hip flexion, hyper adduction and ankle dorsi flexion significant positive correlation by the agility, the rate of hip and knee flexion by power a significant negative correlation and with other lower extremity range motion parameters showed a significant positive association. According to the research findings, seem to be characteristics of the children lower extremity range of motion and identify performance indicators for various athletic field, can be used.

Abstract
The shoulder complex as one of the most moving joints of the body frequently was used by overhead sports athletes. Thus, musculoskeletal screening such as assessment of the range of motion (ROM), and strength variables can be useful to injury prevention strategies and further the development of conditioning and rehabilitation programs. The purpose of this study is to compare selected variables and the ratio of ROM and strength in volleyball, handball, and badminton players. A total of 36 athletes with similar physical characteristics (volleyball: age=26.65±4.56 y, weight=91.07±7.91 kg, height=185.14±12.25 cm; handball: age=27.29±3.12 y, weight=90.11±6.38 kg, height=183.52±9.67 cm, and badminton: age=26.01±4.29 y, weight=87.85±4.59 kg, height=182.38±10.74 cm) were selected to participate in the current study. A Leighton flex meter and hand-held dynamometer were used respectively to measure the ratio of ROM and strength.The results showed that the mean ratio of external(ER) strength to internal (IR) strength and ER ROM to IR ROM were significantly different between the three groups. The post hoc test revealed that badminton athletes had significant differences in all of the measured variables to both volleyball and handball athletes. But there were no differences between volleyball and handball athletes.In conclusion, preseason screening is vital in achieving optimal values on these measures and may reduce future shoulder injuries in overhead athletes.

Abstract
The purpose of this study was to investigate the effect of eight weeks of core stability exercises on upper limb performance based on Y balance test, strength and range of motion of shoulder rotation in badminton athletes. 30 male badminton players were randomly assigned to two control (n=15) and experimental (n=15) groups. The experimental group performed the core stability training program for eight weeks, three sessions a week for 40 minutes, while the control group did not receive any intervention. Measurement of upper limb function was done by Y balance test, and also shoulder strength and internal and external rotation range of motion were measured by handheld dynamometer and goniometer respectively, before and after the intervention. The analysis of the data obtained from the research based on the ANCOVA statistical test showed that there is a significant difference in the average of the Y upper limb balance test between the two control and experimental groups in both dominant and non-dominant hands. which indicates the positive effect of core stability exercises on people's performance in performing the Y balance test (p<0.05); however, no statistical difference was observed in muscle strength and range of motion of external and internal rotation of the shoulder after the intervention. (p < 0.05). It seems that the provision of core stability training programs can be considered with the approach of increasing the performance of the upper limbs and, of course, preventing injuries in badminton players.
