Abstract des Autors
Two studies were performed to estimate the reliability of the Cybex Reactor in assessing agility tasks. In Study 1, participants (n=13) underwent identical testing sessions twice in 1 week. In Study 2, participants (n=13) underwent identical testing sessions twice in 1 week, once 3 weeks later, and once 6 weeks later. Testing sessions consisted of four identical agility tasks requiring participants to react to cues shown on a video monitor. In Study 1, intraclass correlation coefficients (ICC) were .47 for Day 1 and .75 for Day 2 for time to complete each task. Participants performed faster on Day 2 (p<.05). In Study 2, ICC ranged from .58 to .83. ICC between sessions ranged from .59 to .73. Participants performed significantly faster each successive session except between Weeks 3 and 6 (p<.05). The Reactor appears to be reliable in assessing agility tasks with test-retest intervals of up to 6 weeks. Verf.-Referat
