Abstract

, in which weight is placed on the tiptoes, is a fundamental practice for female ballet dancers with pointe shoes. The center of mass (COM) is maintained over the base of support and the relative position of COM to the center of pressure (COP) is especially important when conducting a pirouette in ballet. A pirouette is a fundamental turn in classical ballet with flat shoes and pointe shoes. The investigation of the turn with pointe shoes would be favorable for understanding the movement with limited base of support. Herein, we aimed to determine the differences in the ability to perform pirouettes with pointe shoes between professional and amateur ballet dancers. This study included 8 professional and 9 amateur ballet dancers. The dancers performed a single pirouette, and the movement was captured and analyzed in 3 phases: turning with double-leg support (TDS), turning with single-leg support in pre-swing (TSSp), and turning with single-leg support in mid-swing (TSSm). The analysis focused on the inclination between the vertical angle and the COP-COM line, the vertical maximum reaction force, and the jump-up time in each phase. The results showed no significant differences between the TDS and TSSp. However, professional ballet dancers exhibited significantly lesser posterior inclinations (professional; 2.05° ± 0.90°, amateur; 3.88° ± 1.67°) and jump-up time (professional; 0%, amateur; 1.4% ± 1.3%) than amateur dancers during TSSm. Overall, the findings suggest that professional dancers exhibit superior control skills regarding the COP-COM line than amateur dancers during TSSm. These results may be attributed to the fact that professional dancers can maintain the COM as close to the upright as on the COP without jumping during TSSm. This enables professional dancers to conduct the movements esthetically and continue on to the other movements in the dance phase.

摘要

踮起脚尖承重是穿足尖鞋的女性芭蕾舞演员的一项基本练习。重心(COM)保持在支撑面上方,在芭蕾舞中进行单脚尖旋转时,COM相对于压力中心(COP)的相对位置尤为重要。单脚尖旋转是古典芭蕾舞中穿平底鞋和足尖鞋的基本旋转动作。对穿足尖鞋旋转的研究将有助于理解在支撑面有限的情况下的动作。在此,我们旨在确定专业和业余芭蕾舞演员在穿足尖鞋进行单脚尖旋转能力上的差异。本研究包括8名专业芭蕾舞演员和9名业余芭蕾舞演员。舞者进行一次单脚尖旋转,动作在三个阶段被捕捉和分析:双腿支撑旋转(TDS)、单腿支撑预摆动旋转(TSSp)和单腿支撑中摆动旋转(TSSm)。分析重点关注垂直角度与COP - COM线之间的倾斜度、垂直最大反作用力以及每个阶段的跳起时间。结果显示TDS和TSSp之间无显著差异。然而,在TSSm阶段,专业芭蕾舞演员的后倾角度(专业演员;2.05°±0.90°,业余演员;3.88°±1.67°)和跳起时间(专业演员;0%,业余演员;1.4%±1.3%)明显小于业余演员。总体而言,研究结果表明,在TSSm阶段,专业舞者在COP - COM线的控制技能方面优于业余舞者。这些结果可能归因于专业舞者在TSSm阶段能够在不跳跃的情况下将COM保持在尽可能接近COP的垂直位置。这使专业舞者能够优美地完成动作并继续进入舞蹈阶段的其他动作。
