The specific features of urgent adaptations of a number of functional systems of the body in response to a cycle-ergometric test were under study, and marker criteria for assessing the level of exercise tolerance were identified. Based on the study of heart rate variability, indirect calorimetry, capillary blood flow and a modified PWC170 test, a comparative study was carried out on young men aged 17-19 who were students from among Caucasians born in the North in the 1st and 2nd generations. The results of the study made it possible to establish that the most important and informative indices reflecting the degree of tolerance to the load are the heart rate, the concentration of carbon dioxide in the exhaled air, the oxygen utilization factor, and the rate of capillary blood flow. During the performance of the stress test, such criteria are heart rate, MxDMn in relation to heart rate, reflecting the degree of decrease in parasympathetic activation, as well as the level of oxygen consumption, whose values in individuals with normal load resistance continue to increase until the end of the test.
