The Analysis of Effective Plyometric Exercises on Jump Explosiveness Performance of Women’s Volleyball Athletes

Abstract

The Plyometric training is commonly used to enhance physical performance in various sports including activities that require sprinting, jumping, and agility in changing directions (Kons et al,. 2023) This study investigates the effectiveness of plyometric exercises on female volleyball athletes' jump explosiveness, particularly the setters and liberos of Polytechnic University of the Philippines Women’s Volleyball Team. Through a four-week intervention involving two control groups performing different exercise routines. The participants’ jump explosiveness was assessed before and after the 4-week intervention through the use of Vertec. It is a type of vertical jump assessment that uses coloured plastic swivels arranged in half-inch increments attached to a tube rather than using chalk or being next to a wall. The participants were given three (3) tries with 3minute rest in between using a two-footed no-step approach. (Klavora, Peter 2000) The highest record out of the three (3) tries will be their pre-test and post-test record. The results of this study revealed that a 4-week plyometric training intervention has no significant effect on the jump explosiveness of both controlled groups. It was also revealed in this study that there is no significant difference between the results of both control groups. However, it is worth noticing that both groups exhibited improvements during the intervention. The lack of significant effect in this study may be attributed to the small number of participants (Martínez et al, 2014), low intensity and volume of exercises used during the intervention as well as the duration of the intervention. (Davies et al., 2015).
