Jump testing is fundamental in the evaluation of volleyball players. A basic question centers around how many trials are needed to insure accurate reliability of measurement. The purpose of this study was to determine the reliabilities among selected jump performance tests in female collegiate volleyball players. Varsity players (n = 14) were tested for counteremovement vertical jump (CMVJ), 3-step approach jump (AVJ), drop jump height (DJH), ground contact time (GCT), and reactive strength (RS). RS was determined by dividing DJH by GCT. Each player performed three trials of each test. All single-test reliabilities exceeded ICC>0.922, except for CT (ICC = 0.846). Three-trial reliabilities exceeded ICC>0.943 for all tests. The coefficients of variation (CV) ranged from 15.2 % (AVJ) to 34.4% (RS). Therefore, it appears that several jump trials would be preferable for determining performance ability in volleyball players.
