Abstract
The effectiveness of using video replays to judge gymnastics vaulting was examined by determining reliability of judges' scores and comparing mean scores from original (live) vaults and video replays. Three experienced women gymnasts performed a total of 10 vaults (three different vaults) which were scored by 10 judges after the live vault, after randomized presentation of three replays (regular, slow, and regular speed) and after randomized presentation of one-replay (regular speed). Statistical analyses suggest that variability of scores was greater after the live vault than after either of the replay procedures, judges' reliability may be enhanced with video replays, and the use of video replays may be helpful in reducing variability of scores and producing more consistent mean scores with certain vaults. However, in a comparison of the conventional method of scoring (live vault) with the experimental method (live vault followed immediately by three replays), there was a significant difference between the two methods on only one of the 10 vaults. Further examination of the use of video replays to judge vaulting is suggested.
