The purpose of the study was to examine professional ballet dancers' psychophysiological activation in different types of rehearsal and performance. Electrical activity of the trapezius muscle (EMG), blood pressure, heart rate, and skin conductance level were measured. Self-estimated mental tension was evaluated, as was success in the performance. The effect of sex, age, professional experience, artistic status, role, and type of rehearsal and performance was studied. Principals had lower EMG at rest than soloists or corps de ballet dancers. The principals' psychophysiological activation during performance was increased more than that of soloists or corps de ballet dancers as compared to the values at rest. The type of performance had an effect on self-estimated mental tension and psychophysiological responses. During the last general rehearsals (with an audience) physiological activation was higher than on first nights or in other performances or rehearsals.
该研究的目的是考察专业芭蕾舞演员在不同类型的排练和演出中的心理生理激活情况。测量了斜方肌的电活动（肌电图）、血压、心率和皮肤电导水平。评估了自我估计的精神紧张程度以及演出的成功程度。研究了性别、年龄、专业经验、艺术地位、角色以及排练和演出类型的影响。主角在休息时的肌电图低于独舞演员或芭蕾舞团成员。与休息时的值相比，主角在演出期间的心理生理激活比独舞演员或芭蕾舞团成员增加得更多。演出类型对自我估计的精神紧张程度和心理生理反应有影响。在最后一次总排练（有观众）期间，生理激活高于首演之夜或其他演出或排练。
