Equilíbrio postural de atletas remadores

Abstract

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.

Correlação Do Equilíbrio Estático E Flexibilidade Dos Quadris De Militares

“…São escassos na literatura trabalhos que investiguem o efeito do condicionamento físico sobre a CEC, por meio de parâmetros estabilométricos, sobretudo em testes de longa duração 20 . Entretanto, alguns estudos verificaram que bailarinos 21 e atletas de futebol, judô e ginás-tica 22 apresentam um controle mais refinado das oscilações posturais em função do treinamento físico.…”

Biomechanical reference standards for early diagnosis of disturbances of balance: pilot study

“…Además, no se tuvieron en cuenta estudiantes con lesiones de tejidos blandos, estudiantes que realicen ejercicio físico tres veces a la semana y deportistas, ya que se ha reportado que las personas con estas características presentan un comportamiento atípico en el patrón de estabilometría [18,19,10] .…”

“…Este test permite evaluar la propiocepción conciente en nervios periféricos basado en la premisa que afirma que una persona requiere al menos 2 de los siguientes sentidos, para mantener el equilibrio: Propiocepción, función vestibular y la visión. Cada uno de los participantes fue ubicado sobre la plataforma, manteniendo una posición estable y erguida durante 30 segundos [18] . Se realizaron dos pruebas con cada paciente: a) Sobre una superficie estable se le pide los sujetos mirar un punto fijo designado previamente manteniendo la mirada al frente (estudio etiquetado como OA).…”

Análise comparativa do equilíbrio unipodal de atletas de ginástica rítmica

“…Corrections of the body axis by the mechanisms of posture control, mentioned as a consequence of the dynamics itself of the living organism, provides small and constant oscillations to the human body when at standing position, with an important role in the pressure distribution on the soles of the feet. Some factors may interfere on this posture control, among these, we highlight injuries of the lower limbs, muscular fatigue 6 , asymmetry of the sports gesture, dominance 7 , to name some.…”

“…The stabilometric measurement mostly used in posture control assessment is the area of the center of pressure of the feet (COP), which is defined as the point of application of the result of the vertical forces acting over the support surface 5 . Since the COP dislocation is representative of the posture oscillations, the record is done by the instantaneous calculation of its position in the x and y coordinates, which corresponds to the site in the anteroposterior and mediolateral directions 6 .…”
