Abstract

A variety of performance variables have been proposed as methods of measuring jumping performance including ground contact time (GCT)during a drop vertical jump (DVJ), Reactive Strength Index (RSI), Eccentric Utilization Ratio (EUR), and Elasticity Index (EI). This study assessed the stability reliability and precision of these variables and their associations with DVJdiscplacement in trained men and women. Data for all variables were reliable and precise (ICC > 0.70,CV%< 15.0) except for EURfor both men and women. Correlations with DVJdisplacement were fairly low for GCT, moderate for RSI, and negligible forEURfor both men and women. GCT and EUR explained very little of the variability in DVJperformance andare likely to represent unique performance characteristics not related to DVJdisplacement. RSIaccounts for a portion of variability in DVJdisplacementbut may have limited utility for explaining performance beyond displacement.
