Short-term indices of Heart Rate Variability (HRV) recorded in mine-rescuers men (n=18, mean age 29±1.4
years ranged from 22 to 44 years) before and after the simulated emergency response, organized as a
competition. Within two hours, mine-rescuers used special rescue equipment, administrated the first medical
aid to the conditional victims and performed various tactical tasks. The study group was divided into three
subgroups according to the Stress Index (SI) level. Analysis of time-domain and frequency-domain indices
of HRV was conducted. The biological age, appropriate biological age and ageing rate were evaluated.
It was found out, that the majority of the study group showed signs of neuro-emotional stress even before
the competition. Emotional and physical loads caused by the simulated emergency response increased the
strain of vegetative adjustment, which grew at the end of the competitions. Rescuers with average levels
of SI demonstrated the most sufficient physiological response, while workers with low and high SI levels
referred to the risk groups for disadaptation and cardiovascular diseases. Biological age significantly
exceeded the population norm. SI and biological age can be recommended to use as additional parameters
during medical examinations by the medical services of mine rescue brigades.
