The purpose of this study was to examine basic psychophysiological response levels in professional ballet dancers and the effects of different performances on these responses. Electrical activity of the trapezius muscle, blood pressure, heart rate, and skin-conductance level were measured during a resting state and before, during, and after rehearsals, first-night performances, and shows performed from 10 to 50 times. Subjective mental tension during performance was evaluated, as was performance success. The influence of sex, age, experience, artistic level, role, and the type of performance were studied.
Principals had less tension in the trapezius muscle in the resting state than corps de ballet dancers and soloists. Principals' psychophysiological activation during performances was increased more than that of soloists and corps de ballet dancers as compared with baseline values. The type of performance influenced subjective mental tension and physiological responses. During the last general rehearsals (with an audience) physiological activation was higher than during first-night and other performances. Age and experience did not affect physiological activation. Sex differences in subjectively estimated success and mental tension, as well as in physiological measurements, were small.
