The volleyball spike has been widely recognized as one of the fundamental skills that influence match outcomes. The performance of this skill is largely a function of the orchestration of several biomechanical factors including: angular and linear velocity of the power-arm, launch angle, ball height to the point that it is struck and step stop technique. The purpose of this research was to investigate the influence of these variables in accuracy of spike related to volleyball players in the age group 14-16. The study was descriptive in nature, involving a sample of 7 players from the National Talent Development Centre. Spike accuracy was assessed with the modified high spike test, which evaluates the speed as well as the accuracy of the spike. Biomechanical parameters - i.e. angular speed, peripheral speed, launch angle, ball height at the moment of the strike and foot deviation - were recorded using technological equipment such as high-speed video imaging systems and Kinovea software. The results demonstrates high and significant correlation between biomechanical variables and the accuracy of the spike and equipment contributed to increase angular speed (r = 0.899, sig = 0.006) peripheral velocity (r = 0.965, sig =.000), by ensuring increased accuracy with a projectile in the construction phase. There were also positive outcomes for launch angle and ball height at impact, indicating the significance of these factors for spike accuracy enhancement.
