Football, a game in which two teams of 11 players each compete in different age groups. With great efforts of professional and semi-professional athletes / football players, injuries also occur. The role of the physiotherapist for this reason is very important in the preparatory part of the season. In order for the physiotherapist to best assess the place of origin and the mechanism of injury, it is very important to know the anatomy of hamstrings. The hamstrings are a group of muscles in the back of the thigh, and consist of the biceps femoris muscle, the semitendinosus muscle, and the semimembranosus muscle. They are revived by the sciatic nerve. Different risk factors affect the mechanism of injury. Injuries can be divided into groups into injuries according to the place where they occurred, injuries according to the mechanism by which they occurred and injuries due to the presence of trauma. There are also injuries given the degree of muscle damage. In order to reduce the percentage of these injuries, it is important to focus on prevention. Prevention includes stretching exercises, eccentric and concentric contraction exercises, Nordic hamstrings and risk factors.
