The influence of the external ankle support on the dynamic balance in volleyball athletes

Abstract

The purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players. Seventeen female volleyball players (18.94±2.49 years; 65.45±9.49 kg; 1.71±0.05 m; BMI=22.0±2.67 kg/m²) took part in this study. The dynamic balance was assessed through the Star Excursion Balance Test (SEBT). Comparisons between stabilization (no stabilizer/NS, orthosis/ORT and functional bandaging/FB) modes and the SEBT grid lines and inter-limb were carried out. The SEBT assessment showed a significant difference between the groups NS x ORT and NS x FB (p < .01), and between the lines (p< .01). Significant line/limb interaction in DL and NDL (p< .01) was detected. The external supports tested herein showed similar effects on balance, restricting lower limb's reach in the SEBT execution in some of tested directions.

Avaliação muscular do joelho e funcional de membros inferiores de jovens atletas de voleibol do sexo feminino

“…Para a análise dos valores normativos do YBT, a literatura científica sugere uma pontuação composta acima de 94% e até quatro centímetros de diferença na análise da simetria entre membros, e que resultados abaixo de 94% e/ou acima de quatro centímetros indicam riscos maiores de lesões. 18,37,38 Entretanto, os resultados do presente estudo demonstram valores muito abaixo na análise da pontuação composta, em torno de 83%; resultado similar aos 85% encontrados no estudo de Lima et al 53 também no estudo de jovens atletas do voleibol feminino. Outros estudos com jovens atletas do sexo feminino de diferentes modalidades esportivas também encontraram valores inferiores ao recomendado.…”
