ABSTRACT The purpose of this paper was to investigate if the expertise in Rhythmic Gymnastics (RG) could influence posture steadiness comparing RG gymnasts (RGG) and other sports trained subjects (Non Athletes, NA). A group of 15 high level RGG and a group of 43 female sport university students, NA, were matched in sighted and unsighted postural trials, using a force platform. Data were computed also in a Discrete Fourier Transform and an appropriate two ways variance analysis (ANOVA) with repeated measures. This study revealed the visual dependence for all thesubjects, irrespective of the groups, in their postural trials. Moreover, there were no statistically significant differences in the vision related changes, between RGG and NA groups. Nevertheless, comparing the two groups’ variables (RGG vs NA), data showed gymnasts were more instable in antero-posterior axis and students in mediolateral axis. These results suggested the expertise in RG performance was specialising gymnasts group in the lateral directions postural control. In fact they demonstrated to have a higher range of movements in antero-posterior direction, but it was only in the lowest and shortest frequencies. Furthermore, these high level gymnasts revealed to have better results than students in medium frequencies (from 0.50 to 2 seconds) periods, in which they were trained to perform in RG training routine and competition program.

ABSTRACT The purpose of this paper was to investigate if the expertise in Rhythmic Gymnastics (RG) could influence posture steadiness comparing RG gymnasts (RGG) and other sports trained subjects (Non Athletes, NA). A group of 15 high level RGG and a group of 43 female sport university students, NA, were matched in sighted and unsighted postural trials, using a force platform. Data were computed also in a Discrete Fourier Transform and an appropriate two ways variance analysis (ANOVA) with repeated measures. This study revealed the visual dependence for all thesubjects, irrespective of the groups, in their postural trials. Moreover, there were no statistically significant differences in the vision related changes, between RGG and NA groups. Nevertheless, comparing the two groups’ variables (RGG vs NA), data showed gymnasts were more instable in antero-posterior axis and students in mediolateral axis. These results suggested the expertise in RG performance was specialising gymnasts group in the lateral directions postural control. In fact they demonstrated to have a higher range of movements in antero-posterior direction, but it was only in the lowest and shortest frequencies. Furthermore, these high level gymnasts revealed to have better results than students in medium frequencies (from 0.50 to 2 seconds) periods, in which they were trained to perform in RG training routine and competition program.
