The goal of this paper is to show the importance of explosive strength in soccer training of goalkeepers, to explain its application and to emphasize the skills connected to specific goalkeeper’s tasks during a soccer game. In addition, this paper includes examples of exercises for developing explosive strength. Explosive strength is an ability that is nowadays imposed as a priority in sports because most sports and sport disciplines require a certain level of explosive strength which often represents an advantage in efficient sport performance. An explosive strength workout consists of ballistic and plyometric training while its main objective is improving explosive strength and preventing injuries. The characteristics of the two types of training correspond to the specific goalkeeper’s tasks that one does during a soccer game in order to successfully fulfil them. In order for a goalkeeper to achieve the desired levels of explosive strength, it is important to develop the strength up to an optimal level, which is a prerequisite for a higher level of explosive strength.The position of a goalkeeper is extremely complex and demanding from the perspective of technical–tactical tasks during a soccer game. There is almost no single specific goalkeeper’s action, in which the strength component is not represented, i.e., the strength, in all its forms, plays a crucial role in the efficiency and even in the quality of the performance.
