The purpose of this study is to compare the performance indicators between different football positions using the Global Positioning System (GPS) in Iranian Premier League football players.This is quasi-experimental study. To conduct this research, 18 football players who are members of a club in the Iranian Premier League were selected as the available sample, and the players were divided into 6 groups based on the game post. Then the data related to the players' performance (total distance, distance traveled with maximum speed, duration of maximum speed, maximum speed, sprints, number of accelerations, and number of decelerations) in 6 consecutive matches Collected using Global Positioning System (GPS). Also, one-way ANOVA analysis and SPSS software were used for data analysis at a significant level (α = 0.05).Based on the findings of the present study, between different football positions for the variables of total distance (P≤0.00), distance traveled at maximum speed (P≤0.00), duration of maximum speed (P≤0.00), maximum speed (P≤0.00), sprints (P≤0.00), number of accelerations (P≤0.00) and number of decelerations (P≤0.00) there are significant differences.There are many fundamental differences between the performance indicators of different football positions with each other it is necessary to recognize these differences and it is necessary to consider special exercises according to the physiological needs of each post.

Purpose: The number of damages and severity of the injury has increased in recent years in handball. Recent studies have reported that functional testing before the season is associated with future injuries of athletes. However, the findings related to these studies are inconsistent. The current study aims to examine the accuracy of functional testing to predict the amount and severity of lower limb injuries of handball athletes in Tehran. Method: 80 people of handball players (men) of league clubs of Tehran in the age range of 20-30 years were purposefully selected. Next, functional testing, including the Y balance, single-leg jump, and Functional Movement Screen (FMS) was taken from them. The hours of exercise and competition for teams, along with the number of players' injuries, were recorded during the half-season of competitions. To predict the severity and incidence rate of the injury, the univariate curve estimation regression test was used. Results: The results of this test showed that among functional testing, only single-leg jump (p= 0.035) could predict the severity of the injury incidence, and none of the tests the incidence rate of the injury (p> 0.05). Conclusions: It can be said that only single-leg jump can predict the severity of weak injuries (less than 10 lost days), and screening tests of functional activities have a very limited application to identify the handball athletes at risk of the injury.
