In this master's thesis, I elaborated on the topic "Transformation procedures for improving the efficiency of the jump shot in handball." I divided it into four chapters, which I further divided into groups of exercises and movements that directly affect the improvement and improvement of the quality of the performance of the jump shot in handball. The first chapter is "Development of fitness skills important for improving the efficiency of the jump shot in handball", which I further divided into: fitness exercises for strength, fitness exercises for explosiveness and fitness exercises for stabilization, balance and prevention of injuries due to the performance of the jump shot in handball. The second chapter is "Development of technical operators important for improving the efficiency of the jump shot in handball", where I made a division into: technical exercises for the position of the hand during the execution of the jump shot, technical exercises for the position of the body during the execution of the jump shot (rotation, cover, forward bend) and technical exercises for jumping. The third chapter is "Tactical operators for improving the efficiency of the jump shot in handball" also divided into smaller groups, more precisely into four different positions from which the jump shot can be performed, and as an additional division we have specific situations for each of the positions. These are: jump shot from the position of a winger, jump shot from the position of an outside player, jump shot from the position of a pivot and jump shot from a counter attack. The fourth and also the last chapter of this paper is "The system for assessing the efficiency of the jump shot in handball". There are four aspects that affect the assessment system: anthropometry, fitness aspect (which includes tests for evaluating explosive power and exercises for developing explosive power), technical aspect and tactical aspect.
