Abstract
The incidence of lower extremity injuries in young soccer players is high, but the risk factors for injuries are unknown. Thus, the aim of this study was to investigate relationship between static lower extremity alignment and injuries in adolescent soccer players. Four teams (78 players) playing at Tehran Asia vision adolescence primer league (14-16 years old) participated in this study. Before entering the season Navicular drop, quadriceps angle, knee hyperextension, genu varum and body mass index was measured. Players were monitored for musculoskeletal injuries through a season (7-month period). overall injury rate was 8.7 injuries/1000 player-hours (95% CI=7.01-10.10). Logistic regression modeling indicated that Navicular drop in preferred foot (OR=4.5; p=0.001), Q angel in preferred leg (OR=2.77; p=0.048), and genu varum (OR=4.06; p=0.021) were all associated with injuries but no association was found in other parameters. Players had an approximately 4.5 times greater chance of suffering a lower extremity injury if they have Navicular drop greater than 1.5 centimeter and approximately 2.77 times greater chance of suffering injury if they have Q angel greater than 15.5 degrees. These findings show that multiple anatomic measures such as Navicular drop, genu varum and Q angle can predict soccer players’ injuries. Results of this study are valuable for coaches and players for injury prevention.

Players had an approximately 3.47 times greater chance of suffering a lower extremity injury if they have Navicular drop greater than 1.5 centimeter and approximately 2.77 times greater chance of suffering injury if they have Q angel greater than 15.5 degrees. These findings show that multiple anatomic measures such as Navicular drop, genu varum and Q angle can predict soccer players’ injuries.

Abstract
Functional Movement Screen Test is one of the tests used to identify asymmetries and limitations in basic and fundamental movements. For time management and fast execution of this test, some researchers have suggested reducing the number of tests. The purpose of the present study was to investigate the internal consistency and correlation between components of this test. The present study was a correlational study. In this study, movement screen test was performed on 165 male and female students aged 18 to 25 years of Shahid Beheshti University using a special FMS kit. Results: The internal consistency of the test, measured by Cronbach's alpha method, was acceptable (α=0.71). The results of multivariate regression test showed that there was a low to medium correlation between the internal components of the test, but a high correlation was observed between the test components and the final FMS score. The results also showed a high correlation between the "four small movements" (Active leg raising, shoulder mobility, stability push up and rotary stability) and the total FMS score and a low correlation between the "three big movements" and the FMS score. Motor function screen test is a valid tool for evaluating motor performance. The results also show that in large communities such as students, and if there is a time limit, "four small movements" can be used instead of seven.
