Does the Amount of Jumping with Respect to Positions During Volleyball Matches Affect the Team Success at the End of the Season?

Abstract

In many sports like volleyball, jumping, balance and explosive strength which are biomotor abilities have become more important day by day to succeed. Athletes focus on games at game period so the time that they spend for improving their biomotor abilities can be less. Therefore, performance that obtained in preparation period and sustaining that performance in whole season affect significantly team rank at the end of the season. In the lights of these informations, the affect of amount of jumps with respect to different positions was investigated in major league of Turkey in 2013-2014. There were 149 female volleyball players between the ages 17-27 (age 24.19 ± 2.42) in this study. 12 teams competed with each other and 125 games that is 455 sets were evaluated. Moreover; videos were analyzed three times by experts. Number of jumps in serve, block, spike and setting were recorded. Spearman Brown Order Differential Correlation Coefficient was used for determining the relations between dependent and independent variables and descriptive statistics in analyzing datum. In addition to this, Multiple Linear Regression Analysis was used for investigating regression level between independent and dependent variables. As a result of this, middle blockers jumped the most (M=155.86, SD=39.77) while opposites jumped the least (M=73.31, SD=23.49). The amount of jumps of wing spikers (r= -.130, p<.05) and middle blockers (r= -.185, p<.01) was negatively related with team success at the end of the season in low level. The total amount of jumps in different positions was negatively related with team success at the end of the season in low level too (r= -.156, p<.01). Setters, wing spikers, middle blockers and opposites were listed with respect to regression factor (ß) and their importance level for team success at the end of the league. In conclusion, number of jumps in different positions at game time affects team success positively.
