In this graduate thesis, the aim is to present and explain the application of goalkeeper strength training, as well as the importance of ability to perform specific goalkeeping tasks during the football game. The graduate thesis will also include examples of exercises for developing the aforementioned ability of the goalkeeper. Power represents the ability to resist resistance at high speed of contraction. In mechanics, power is defined as the ability to perform mechanical work in a unit of time. Strength as a motor skill of the goalkeeper, certainly plays an important role in achieving desired results and optimal state of preparedness, in relation to the specific requirements of the soccer match or effectively solving the situation tasks. The development of explosive power in goalkeeper training can be achieved by using ballistic and plyometric training. Features of these two modes of training correspond to the specific goalkeeper's actions that goalkeeper performs during the soccer match in order to successfully fulfill his tasks. To achieve the desired level of explosive power, it is important to develop an optimum level of strength that is a precondition for a higher level of explosive power.
