Physiological ‘cost’ of activity of individuals with different effectiveness in dynamics of endosurgical training

Aim. The work was designed to study the physiological ‘cost' of purposeful behavior on the model of endosurgical training. Materials and Methods. The research was implemented on 87 men of 18-24 years of age. The volunteers per formed a number of exercises 30 minutes each according to the Basic Endosurgical Simulation Training and Attestation System (BESTA system) on a T5 Large RM box-trainer within 10 consecutive days. The total time and the number of mistakes were recorded. During the training sessions an electromyogram was recorded on a BIOPAC MP 36 device. ECG was recorded and processed using a Varicard 2.51 device before and after the training sessions. ECG was analyzed by evaluation of the average differences of spectral analysis of heart rate variability before and after training. Results. It was shown that high-performance individuals were characterized by less energy spent on motor work in purposeful activity. Irrespective of the effectiveness of training, the purposeful behavior in conditions of psychoemotional stress was characterized by depletion of functional reserves of an organism. Low-performance subjects demonstrated a more evident weakening of parasympathetic (start of observations) and of sympathetic influences (end of observations) on the functional activity of the heart. Conclusion. Specific features of physiological ‘cost' of purposeful behavior in individuals with different effectiveness of the activity were revealed on the model of endosurgical training. Better results in the dynamics of purposeful activity were achieved on this model at a higher physiological ‘cost'.
