Cross-cultural study of the functional states dynamics under mental and emotional workload

By means of three-factor model of heart rate variability the dynamics of functional classes under mental and emotional workload was analyzed in homogeneous groups of Russian (N=169, mean age = 24.7, SD = = 2.20 years), Iranian (N=150, mean age = 25.9, SD = 2.15 years) and China (N=104, mean age = 25.0, SD = 2.07 years) healthy male subjects. The functional classes were investigated during professional selection of atomic station operators. ECG recordings were made before task (emotional impact of forthcoming test), during mental task (mental impact of workload) and recovery (emotional impact of test results). The classification of functional classes in terms of three-factor model of heart rate variability was presented. The differences of the dynamics of functional classes in groups on three periods were described. The specific features of the dynamics of emotional arousal functional classes and mental strain functional classes were attended.
