ABSTRACT

One of the basic skills of a dancer is the ability to keep the body balance (aplomb) while performing various dance figures. These movements are often performed with limited vision control due to dynamic motion or environmental conditions. Our aim was to verify whether the exercises with eyes closed of the ballet school students would reduce postural sway whilst improving the body balance. The training without visual feedback forces the body to rely more on information from the proprioceptive system about the alignment and motion of body parts in relation to each other and the external environment. In a group of thirteen female students of Comprehensive Ballet School, a significant reduction in postural sway was already found after three weeks of the nine-week training. This phenomenon occurred only during quiet standing with eyes closed. The use of stabilographic testing can be recommended as an objective evaluation of the aplomb level in ballet dancers. At the same time, this research showed that the introduction of ballet exercises with eyes closed improved postural stability without compromising stability with eyes open. Therefore, it can be assumed that such exercises do not harm but rather may be beneficial for the development of aplomb.

摘要

舞者的基本技能之一是保持身体平衡的能力（沉着) 在表演各种舞姿时。由于动态运动或环境条件，这些运动通常在有限的视觉控制下进行。我们的目的是验证芭蕾舞学校学生的闭眼练习是否会在改善身体平衡的同时减少姿势摇摆。没有视觉反馈的训练迫使身体更多地依赖来自本体感受系统的关于身体部位相对于彼此和外部环境的对齐和运动的信息。在综合芭蕾舞学校的 13 名女学生中，在为期 9 周的训练后的 3 周后，已经发现姿势摇摆显着减少。这种现象只发生在闭眼安静站立时。可以推荐使用稳定性测试作为客观评估芭蕾舞演员的沉着水平。同时，这项研究表明，闭眼芭蕾舞练习的引入提高了姿势稳定性，而不会影响睁眼时的稳定性。因此，可以假设这样的练习不会伤害而是可能有益于沉着的发展。
