Abstract
The purpose of this study was determining validity and reliability of the Athlete Fear Avoidance Questionnaire (AFAQ). For this purpose, 120 atheltes with different levels of skills in different fields, were chosen and completed the the AFAQ, the Kinesiophobia Questionnaire, and the Pain Catastrophizing Scale and the Sport Injury Appraisal Scale. AFAQ was confirmed by using translation-back translation method and face validity and translation accuracy. Cronbach's alpha index, exploratory and confirmatory factor analysis, Pearson correlation coefficient and intraclass correlation coefficient were used to check construct validity, internal consistency and temporal reliability. The results showed that the one-factor model of the athletes' fear-avoidance questionnaire had a poor fit, for this reason, after conducting the exploratory factor analysis and identifying three factors in these questionnaires, the confirmatory factor analysis model also fitted the data well with this the three-factor model. So that the CFI index was 0. 96 and the TLI index was 0. 94 as well as the RMSE index of 0. 05 and the chi-square ratio to the degree of freedom(X2/DF) was 1. 39. The internal consistency of the questionnaire was also confirmed. Based on this, the Persian version of the AFAQ has 3 factors and includes 10 questions and three catastrophic constructs (items 1, 5, 8), fear of movement (4, 6, 7) and fear-avoidance beliefs (items 2, 3, 9, 10) was confirmed in the community of Iranian athletes.

Abstract
The purpose of this study was to compare the prevalence of injuries in the Iranian Football Premier League players before and after the outbreak of Coronavirus (COVID-19) through video analysis in the 2019-2020 season. The types of sports injuries were divided into acute and chronic categories based on the mechanism, and the injuries were analyzed by reviewing 143 videos from 239 matches. Prevalence, time of onset and affected area were recorded in a special sheet. According to the results, 219 injuries occurred before the outbreak of coronavirus and 276 injuries occurred after the outbreak of coronavirus. In the period before and after the outbreak of Corona virus, the lower limbs of the players (58/7%) were damaged more than other parts of their bodies. Also, the highest rate of injury occurred after the outbreak of coronavirus than before in the last minutes of the game (24/3%). Research Findings showed that the prevalence of injuries in Iranian Premier League football players in the post-outbreak period of Coronavirus increased due to home quarantine and closure of matches.
