Develop Vertical Jump to Junior Volleyball Players by Plyometric Special Means

Abstract

Volleyball is part of the explosion-based sport, fast in a very short time [10]. Vertical jump is extremely important both phases of attack and in the defense [6]. So attack and block 45% of all game action, and in terms of the achievement points, they represent 80% [11].
For this, it is important to develop effective training programs that will increase the ability of jumpers to volleyball by coaches. In order to achieve these programs, they need to get information on physical issues in general and volleyball in particular [12].
The main goal was to structure a set of exercises and implement them in volleyball training at the juniors level in order to develop the performance indexes of the vertical jump.
Hypothesis research is we assume that by introducing a specially designed exercise complex, we can record higher vertical jump indexes at final testing compared to the initial test.
The plyometric method was used to develop the vertical jump, and the methods of research were the method of data organization and presentation, the graphic method, the mathematical-statistical method, the classification/ordination method, the comparison/reporting method.
The conclusions of the research were that, following the implementation of the vertical jump development program, the working hypothesis was confirmed, is an increase in vertical jump specific parameters.
