THE EFFECT OF BLOCK MOVEMENT DONE BY DIFFERENT APPROACHES ON THE HEIGHT OF JUMPS IN VOLLEYBALL

Abstract

Aim. The effect of blocking done by different approaches on the height of jumps was aimed to be determined in our study. Materials and methods: 6 female athletes (age 18.83 ± 2,137 years, bodyweight 64.83 ± 9,020 kg, height 174.50 ± 7.503 cm, training years 5.33 ± 2.733) of Kocaeli Province Ihsaniye Sports Club participated in the study voluntarily. In determining the performance parameters of the athletes, vertical jumping, sidestep block jumping, and cross-step block jumping tests were performed. The tests were recorded with two Basler 120 FPS cameras and analyzed with the Simi Motion 9.2.0 software. Results. As a result of the tests conducted, no significant difference was found between sidestep block jumping and vertical jumping (p > 0,05). On the other hand, significant difference was found between cross-step block jumping and sidestep block jumping, and between vertical jumping and cross-step block jumping (p < 0,05). Since the best jumping height is achieved with cross-step blocks, going for this block technique in the game will affect the performance of the match and athlete positively. Conclusions. As a result, the best jump height was obtained from the block done with cross-step block jumping. Considering that volleyball is a defense game, these increases in the block performance of the players will directly affect the result.
