VIEIRA, Taian de Mello Martins and OLIVEIRA, Líliam Fernandes de. Postural balance in rowing athletes . Rev Bras Med Esporte [online]. 2006, vol.12, n.3, pp.135-138. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922006000300005.
The influence of fitness on long-term postural balance is not clear yet. This study aims to compare stabilometric parameters in long-term balance tests performed by rowing athletes and by a control group of non-athletes healthy subjects, who stood upright on a force plate for 31 minutes. At every five minutes of test, a modified Borg scale was shown to the subjects to score the discomfort. The parameters studied were: standard deviation, average velocity and average frequency of the lateral and anterior-posterior centre of pressure displacements, and the elliptical area of the displacement on the level of the force plate. The athletes did not show significant differences in parameters during the entire test. The control group presented significant higher values in the elliptical area and in average velocity from the middle to the end of test. The athletes presented significant lower values in Borg's scale, showing a greater resistance to discomfort. It is suggested that stabilometric alterations showed by the non-athletes occurred in response to peripheral physiological processes, and that physical fitness seems to be an important factor for the maintenance of a long-term static balance.
