Tennis is a game where, due to specific motion movements, the locomotor system is too loaded. Specific elements of tennis game can occure significant number of injuries which are related to upper extremities. In order to avoid injury or to reduce their number, it is necessary to pay more attention on how to prevent them. The main goal of this graduate thesis is to systematize the knowledge of types and frequency of upper extremity injuries in tennis, with reference to specificity and variety of the movement in tennis, and to point out the importance of injury prevention that can be achieved through planned and targeted specific prevention training programs, coordinated with an individual assessment and focused on individual needs of tennis players. In this research, the most common upper extremity injuries are described because of specific motions and movements during the execution of tennis shots. In order to control and reduce risks of injuries, many prevention trainings and warm up exercises that need to be perform before each training, are shown in this research and it will prepare different types of muscles from upper extremities, more specifically the shoulder, the elbow and the wrist, for upcoming training or competition. Since injuries may disrupt activity and divert athletes from field for a longer period of time and even lead to career breaks when it comes to professional engagement in sports activities, prevention programs should have their place in each cycle of sports preparation and they must be performed systematically and regularly.
