Abstract
The purpose of this study was to examine reaction time in a group of Division I female volleyball athletes. Data was collected over a consecutive four-week timespan using the Dynavision D2 training system. The Dynavision D2 training system consists of a mounted board with a series of light-up buttons and a screen in the middle, also referred to as the t-scope. In this study, buttons would light up, at random, for one second at a time. Athletes were tasked to press each button as fast as possible before the next button would light up. In addition, the t-scope screen presented a series of three-digit numbers or basic addition and subtraction math problems, at random, that athletes were asked to verbalize or solve. Athletes participated in three, 30 second trials each week for four weeks. Descriptive statistics were calculated for overall reaction time, accuracy, and number of missed three-digit numbers or math problems, also referred to as the t-scope score, amongst the different position groups including the left sides, right sides, middles, liberos, and setters. Z-scores were used to determine overall performance. Overall, the left side position group had the highest accuracy (93.95%), fastest reaction time (M=0.62, SD=0.04 seconds), and best overall performance (z=0.33). The setters had the lowest number of missed t-scope scores per athlete (M= 2.00, SD=1.41) amongst all position groups. These findings suggest that reaction time and accuracy amongst position groups are different and the demands between position roles on the court may vary.
