RESUMO

The objective of this study was to evaluate the characteristics of the balance of rowers trunk, in the seated position. The research is characterized as descriptive exploratory, having 30 rowers of the male sex with age between 15 and 28 years old as participants. The data was collected using the Board of balance, developed by Soares (2004), constituted of a convex inferior surface, which possess 5 concentric rings divided and isolated in 8 parts, arranged in a total diameter of 76 mm ( 0,01). The analysis of the data was preceded starting from Shapiro-Wilk s Normality test, followed by the Wilcoxon and Kruskal-Wallis tests. Through the results it was noticed that the visual information influenced in the maintenance of the balance when the rowers were with two feet in contact with the soil. It was verified a heterogeneity in the characteristics of the log balance for each group related to the visual information, when the rowers were with the support of the dominant foot in contact with the soil. When the rowers were with the support of the foot non dominant in contact with the soil, with and without visual information, the results showed that there was probably compensation among the sensorial systems and that the visual information seemed to influence in the maintenance of the equilibrium. The results indicated that with the support of the two feet in contact with the soil with visual information there are differences in the oscillations among the rowers groups, and among the rowers groups just Team and PreTeam didn t show difference in the performance. When was analyzed the support of the two feet and of the dominant foot in contact with the soil with visual information, it was observed that just in the group of the rowers Team didn t happen significant differences in the acting of the task, however it wasn t noticed differences in the acting of the tasks when the support of the foot in the soil was made with the dominant and with the no dominant foot. The results regarding the characteristics of the balance of rowers log, in the seated position, with different supports of the feet in contact with the soil, without visual information, showed that there weren t significant differences among the acting of the equilibrium of the rowers log, in the three different supports of the feet. It is conclude that this study brought subsidies to affirm the hypothesis that the log balance in the seated position is directly related to the concepts of the control of the balance in the stand position, being able to this way come to contribute for the subject that involve the development, the performance of the human balance, as well as for the aspects of the rowers technical training, being necessary a continuity in the investigations, for to have others information that will make possible a better understanding regarding the trunk balance, in the seated position for different populations.
