Determining the Explosive Power Level of the Lower Limbs to the Women’s Volleyball Team Csu Medicina Tg. Mures in the Competitional Season of 2022-2023

Abstract

Explosive lower body strength in volleyball is a constant challenge for every coach and physical trainer who is involved in training a team. The concern is mostly important not only due to the vertical jump but also due to the movement in the field. During the game of volleyball, because of the small dimension of the court, the first 2-3 steps, the starting steps are crucial in the successful execution of each phase during the game. Methods. To determine the area of interest in a representative volleyball team, we applied two tests using the optojump device, as follows: 15 sec jumps test and 30 sec jumps test. Objective. These two tests were performed at the beginning of the training season in order to see the level of explosive strength parameters Results. These parameters were analyzed for each subject, as well as for the entire tested team. The average height reached by the center of gravity for the entire team during the 15 sec jumps test is 20.1 cm, while the average jumps in the 30 sec jumps test is 16.6 cm. Analyzing the explosive force parameters shows the direction in which the team’s physical training should be designed. Keywords: volleyball, optojump, explosive power
