 abstract={In many sports disciplines, competitors perform activities that are not directly evaluated by referees, and whose time, length, or height are not directly measured, but which determine good sports results. In the case of trampolining, such activities involve the jumps that precede the program during competitions. Those preparatory jumps help the competitor perfom jumps for which he can receive the best notes. By undertaking research on the importance of preparatory activities in trampoline jumps, the authors decided to discover the interdependence between the number of preparatory jumps and the quality of the performance.},
 abstract={The aim of the article was to experimentally indicate the optimal number of performed jumps before starting the program. The authors used an experiment involving 4 elite competitors in trampolining: two juniors had the first sports class and two had the master class. Having done 4, 6, 8, 10, 12, 14, and 16 preparatory jumps, the competitors performed a program consisting of 5 elements. Two qualified referees, using a measuring device, evaluated the performed program. It turned out that in 3 cases the best jumps were performed after 8 preparatory jumps, and in 10 cases, after one jump. Fewer than 8 and more than 10 jumps lead to worsening the quality of performance. This conclusion is a valuable practical tip for coaches.},
