The article presents data on the features of functional reserves, the level of biological adaptation, mental performance of students by the profession driller. We found that more than half of the adolescents had reduced adaptive reserves of varying severity. Thus, the level of functional reserves, which was reduced relative to the physiological norm, was noted in 89 % of the 1st year, 83.4 % in the 2nd year and 93.3 % in the 3rd year students. In parallel, there was the growth trend to the 3rd year of study from the students number with reduced performance (from 27.6 % to 33.3 %) and an increase by 1.6 times of the students number with a significantly reduced level of performance.

We carried out the nutrition ration hygienic assessment in two groups of students who are getting an education to become drillers in an oil-gas exploration college. The first group involved students aged 15– 17, 2nd group – students aged 18–20. The diet for students from both groups is intake in below of principles quantitative and qualitative characteristics of balanced diet. The diet of 15–17 years old students (1st group) is described below by the following indicators: fat content is reduced by 40,6 % rate, potassium – by 45,9 %, iodine – by 47,9 %, phosphorus – by 10,1 %, and iron content raised by 35,3% from the physiological norm; in the diet of the 2nd group reduction of fat content by 20,8 %, iodine by 54,9 %, calcium by 35,1 % and overlimited concentration of proteins by 49,3 %, carbohydrates by 28,9 %, iron by 102,9 %, phosphorus by 102,5 % was also found.
