Elite dancers often engage in mental practice during training, but little is known about the effects of discrete, repetitive motor imagery on dance movement performance. This study compared the effects of two motor imagery modalities, third-person visual imagery and kinesthetic imagery, on hip and pelvis kinematics during two technical dance movements, plié and sauté. Twenty-four female dancers (mean age: 26.04; mean years of training: 19.63) were randomly assigned to a type of imagery practice: visual imagery (VI), kinesthetic imagery (KI), or a mental arithmetic task control condition (MAT). No statistically significant effects of imagery group or task type were found for external hip rotation, sagittal pelvic excursion, or a ratio relating hip to pelvic movement, suggesting that imagery practice did not affect either temporal or kinematic characteristics of the plié or sauté.
优秀的舞者在训练过程中经常进行心理练习，但对于离散的、重复性的运动想象对舞蹈动作表现的影响却知之甚少。本研究比较了两种运动想象方式，即第三人称视觉想象和动觉想象，对两种舞蹈技术动作（蹲和跳跃）中髋关节和骨盆运动学的影响。24名女性舞者（平均年龄：26.04岁；平均训练年限：19.63年）被随机分配到一种想象练习类型：视觉想象（VI）、动觉想象（KI）或心算任务控制组（MAT）。在髋关节外旋、矢状面骨盆偏移或髋关节与骨盆运动的比率方面，未发现想象组或任务类型有统计学上的显著影响，这表明想象练习并未影响蹲或跳跃的时间或运动学特征。
