Research methods and organization Practical application of information analysis about football game and injuries epidemiology in football. Skābardis, J. Čuprika, A. Čupriks L. Latvian Academy of Sport Education, Riga, Latvia Results Background Conclusions Latvian Academy of Sport Education (LSPA) along with Football School METTA personnel is organising a pilot project for a research dealing with practical application of the information about analysis of football games and injury prevalence. The aim of this study was to explore the role of development of knee joint flexors and extensors in football. Interval nature of football game. The total volume is ~ 10-13 km, it differs for position on the pitch, the chosen tactics, as well as the players' tactical and technical training. The main difference between elite and amateur levels is the total volume of high intensity activity. It is ~1 km at elite level. Acceleration and sprint distance 9-27 m. Leg segments are injured most often (82.9 – 89.6%), more specifically – knee joints and thighs. Having examined more details results in terms of types of injuries, we found out that muscle/tendon injuries are most common (35%↑). More detailed classification indicates femoral muscles (especially muscles of the posterior part). Injury effects have been released competitions and training lessons, which in turn reduces the competition performance improvement opportunities. The analysis of the information on injury mechanisms revealed that the most common knee injuries are related to the loss of balance after landing, after an abrupt change of direction. Knee flexor injuries revealed that injury mechanisms are related to the end of swing stage when running and at the moment of contact with the ground. the most common injury mechanisms of quadriceps femoris are related to sprint and ball strike. When testing knee flexors and extensors, testing position should be as similar to the conditions of the game, running cycle as possible. 1. A set of exercises should be developed and approved for prevention of knee flexor and extensor injuries and strength development. 2. The testing procedure should be improved and it should include conditions/ body positions that are close to the game in order to obtain appropriate data about muscle functions and their functional state in game-specific conditions. 45° Research methods and organization The methods employed for the study include review of literature and meta-analysis. The information from the sources dealing with physiological requirements of football games, physical parameters during the game were summarised and analysed. We searched the sources for the information about the frequency of injury prevalence and its location in the body from the point of view of sports medicine. We also examined biomechanical parameters of the most common injuries and analysed movements during such injuries. References Bangsbo J, Mohr M, Krustrup P.
