This study compared lower limb external rotation kinematic patterns during sautés in first position in beginners and experienced ballet dancers with various training backgrounds. The ability to attain a perfect turnout is traditionally thought to be a fundamental aspect of classical ballet, and turnout is identified in the literature as one of the leading causes of dance-related injuries and technical limitations among dancers. Twenty-eight ballet dancers of different technical levels and methods (three groups) were assessed. Coefficients of variation (CV), range of motion (ROM), and mean external rotation angles of hip, knee, and ankle in first position sauté were calculated. Differences among groups were tested with ANOVAs (Tukey's post hoc; p < 0.05). The hip mean external rotation values found during the jump were different between both experienced groups from different training backgrounds (p = 0.02). The inexperienced group presented a significantly greater hip external rotation CV compared to the experienced groups (p ≤ 0.001). There were no differences between groups for values of external rotation at the knee and ankle. It is concluded that higher technical level dancers produce lower variability of hip external rotation while performing sauté in first position. Ballet training background also seems to influence the hip external rotation pattern. Moreover, the knee contributes decisively to turnout composition, not only the hip, as expected.
本研究比较了初学者和具有不同训练背景的经验丰富的芭蕾舞演员在一位 sauté 动作中下肢的外旋运动学模式。传统上认为,能够达到完美的外开是古典芭蕾的一个基本方面,而外开在文献中被确定为舞蹈演员与舞蹈相关损伤和技术限制的主要原因之一。对 28 名不同技术水平和训练方法的芭蕾舞演员(三组)进行了评估。计算了一位 sauté 动作中髋关节、膝关节和踝关节的变异系数(CV)、运动范围(ROM)和平均外旋角度。组间差异采用方差分析(Tukey 事后检验;p < 0.05)进行检验。来自不同训练背景的两个经验丰富的组在跳跃过程中发现的髋关节平均外旋值不同(p = 0.02)。与经验丰富的组相比,无经验的组髋关节外旋 CV 显著更大(p ≤ 0.001)。膝关节和踝关节的外旋值在组间没有差异。得出的结论是,技术水平较高的舞者在一位 sauté 动作中髋关节外旋的变异性较低。芭蕾舞训练背景似乎也会影响髋关节外旋模式。此外,膝关节对外开的构成也有决定性作用,而不仅仅是如预期的髋关节。
