To provide the export requirements and its own energy security, fuel and energy complex of Russia builds a new oil and gas production centre in mainland European polar region. With a view to establishing the features of formation of fatigue in the dynamics of the shift period surveyed practically healthy males number 69 people (age 39.6 ± 3.6 years) held primarily by oil hardly operator. Tepping-test with calculation of fatigue (KU), is one of the methods to evaluate the characteristics of the motor speed, tempo and resistance of motor actions. Comparison of independent groups of data outside the normal distribution law, was carried out using non-parametric test, Wilcoxon Signed Ranks Test, non-parametric Mann-Whitney test and the test is Exact. The results are presented as median (Md), 25 and 75 percentile. Critical significance level (p) was equal to 0.05.

An analysis of the dynamics of the emerging fatigue showed that Ku, designed for right and left hands in workers maintained quite equal in magnitude to the Middle watch, then regardless of the working and rest time regime significantly changed upwards (p2-3 < 0.0001). The average value was used to compare the DF parameter from the oil companies for length of service and age. In the Group of oil employed in polar region for more than 10 years, starting from the Middle watch, there has been significant growth in size, reaching a maximum value to its end (p2-3 < 0.0001). In age groups (30-39 years 40-59 years old) received credible DF values change towards its increase since the middle of the shift period (p1-3 =0,009; p2-3 =0,022) and (p1-3 <0.0001; p2-3 <0.0001) respectively, that suggests more intense exposure for this group of people and can be used to register the lower period of steady work, and thus the time spent on duty. Thus the least prone to exhaustion with work experience of up to 10 years in the first age group (18-29 years). More vulnerable are the oil companies with experience in the polar region for more than 10 years of age and 30 years of age or older. Use the tepping-test early enough and precisely identify the formation of fatigue among the study population, and hence to make timely adjustments in the working and rest time regime for specific working conditions.
