Motor imagery is a type of mental practice that involves imagining the body performing a movement in the absence of motor output. Dance training traditionally incorporates mental practice techniques, but quantitative effects of motor imagery on the performance of dance movements are largely unknown. This pilot study compared the effects of two different imagery modalities, external visual imagery and kinesthetic imagery, on pelvis and hip kinematics during two technical dance movements, plié and sauté. Each of three female dance students (mean age = 19.7 years, mean years of training = 10.7) was assigned to use a type of imagery practice: visual imagery, kinesthetic imagery, or no imagery. Effects of motor imagery on peak external hip rotation varied by both modality and task. Kinesthetic imagery increased peak external hip rotation for pliés, while visual imagery increased peak external hip rotation for sautés. Findings suggest that the success of motor imagery in improving performance may be task-specific. Dancers may benefit from matching imagery modality to technical tasks in order to improve alignment and thereby avoid chronic injury.
运动想象是一种心理训练方式，它涉及在没有运动输出的情况下想象身体执行某个动作。传统的舞蹈训练包含心理训练技巧，但运动想象对舞蹈动作表现的量化影响在很大程度上尚不清楚。这项初步研究比较了两种不同的想象方式，即外部视觉想象和动觉想象，对两种舞蹈技术动作（蹲和跳跃）中骨盆和髋关节运动学的影响。三名女性舞蹈学生（平均年龄 = 19.7岁，平均训练年限 = 10.7年）每人被分配使用一种想象训练方式：视觉想象、动觉想象或不进行想象。运动想象对髋关节最大外旋的影响因方式和任务而异。动觉想象增加了蹲动作中的髋关节最大外旋，而视觉想象增加了跳跃动作中的髋关节最大外旋。研究结果表明，运动想象在提高表现方面的成功可能因任务而异。舞者可能会从将想象方式与技术任务相匹配中受益，以改善身体姿态从而避免慢性损伤。
