Background: The injuries to the hamstrings represent the most common muscle injuries in professional football and they happen due to the high speed running which is the essential motoric task in the football play. Subsequently, these high speed running acts are responsible for success during the game, or simply said the score. It is documented that the higest number of goals are scored precisely during situations where dominantly linear sprints are incorporated. Due to the high incidence of injuries during high speed running and massive importance of repetitiveness of this motor task during the football game, it is necessary to adequately document these injuries in order to establish the most effective approach to this more and more emerging problem. The right documentation and recognition of growing trends in muscle injuries in general, and of the hamstring muscle group injuries specifically, represents the first step in prevention of this class of injuries, improves availability of players and enhances the success rates of the entire team. Methods: The study was conducted in players of senior and developing (junior) team in an elite football club in Asia. In one competitive season, with the use of internal club database, there were documented all injuries of both teams that caused the player absence longer than three consecutive days. The teams varied in the number of subjects, age, number of contests they participate in and exposure in competitive matches. The aim of this research was proving which team would develop more muscle injuries, would the most of these injuries be the hamstring injuries and which of the teams would suffer from the highest number of the injuries in the forementioned hamstrings. Results: During the season of 2020/2021, there were 63 injuries in the first team, whereas in the second team only 33, in spite of the greater number of players of the second team participating in the matches. The hamstring muscle injuries did not dominate in the group of four most common muscle injuries of the lower extremities as it was anticipated considering the long term studies that were previously conducted in the elite football clubs across Europe. The greater number of muscular injuries to the hamstrings has been documented inside the first team, which was expected due to the bigger demands in terms of the number of leagues and the number of matches played per team, entangled with the risk factors of the senior group, opposed to the developing one. Conclusion: Based on the small sample of subjects in the conducted research, I cannot derive a firm conclusion. More documentation and following of this pair of subject groups should be considered in order to potentially identify the trends regarding muscle injuries to the hamstrings. On the other side, to give the relevance to the study, more elite football clubs that participate in the same leagues and competitions should be included in the future studies, but also to draw a parallel and derive similar conclusions regarding the European clubs of same level.
