Countermovement jump performance and associated biomechanical variables are commonly used to monitor athletes` neuromuscular function. The purpose of this study was to quantify the reliability and usefulness of these variables in a cohort of fourteen elite male rowers, and to apply these findings in individual athlete monitoring. Seven of the nine variables demonstrated acceptable reliability (CV < 5%). Peak power was classified as OK for usefulness (CV ˜ SWC; signal-to-noise ratio ˜ 1) while all others were classified as poor. Within the athlete monitoring program, many of the observed changes in countermovement jump variables exceeded the threshold for interpretation of a clear change based on the signal-to-noise ratio. This study demonstrates the importance of understanding the reliability and usefulness measurements for accurate interpretation of monitoring data.
