Materials and methods. The study involved 41 cadets of a military university of males aged 18 to 21 years. Hypoxic normobaric hypoxia was caused by respiration of a hypoxic gas mixture with 10% oxygen content. Synchronously recorded: minute volume of respiration and respiratory rate, saturation of hemoglobin of blood with oxygen by pulse oximetry, electrocardiogram. Results. The concentration of oxyhemoglobin in the blood flowing from the lungs is different in different subjects, which indicates an individual adaptation strategy to hypoxia under approximately equal conditions of gas exchange in the lungs. Conclusion. The data obtained allowed us to distinguish two groups of people by changing the saturation of hemoglobin of blood with oxygen in response to hypoxia: “stable” and “unstable”. According to the results of various tests, physical performance also varied: in the 1st group of “stable”, more effective mobilization of functional reserves was revealed, due to which the total value of erforming bicycle ergometric load was significantly greater than that of the whole sample as a whole and in the 2nd group “unstable” (3 tables, bibliography: 13 refs).body adaptive capabilitiescadetshypoxic hypoxiamilitary personnelphysical activityrespiratory systemадаптационные возможности организмавоеннослужащиегипоксическая гипоксиядыхательная системакурсантыфизическая нагрузка[Agadzhanyan N.
