A Motion Analysis of Volleyball Open Spike: Kinematics and Performance

Abstract

The purpose of this study was to analyze the open spike motion to identify the performance of Semarang Elite Athletes. The open spike technique in volleyball is indispensable as an attacking strategy because it has a high potential to score. The type of research used is analytical research with a research method in the form of One Short Case Design. The population in this study consisted of 11 PORPROV 2022 athletes and was taken using total sampling. This research was carried out at the PBVSI (Indonesian Volleyball Federation) of Semarang City and each sample had signed an informed consent as evidence of approval for the research carried out. The data in this study were obtained from video recording analysis when the sample did an open spike by using Dartfish version 8.0. The results showed that the average time value achieved by volleyball athletes in Semarang was 1.01 seconds and the average impact was 0.57 seconds. This shows that the spike done by the athlete is quite effective. This study has limitations because it only measures kinematic data, so it is hoped that further research can be deepened by measuring kinetic data such as arm strength and leg muscle explosive power on the results of the open spike carried out.
