Material and Methods: in a study involved 44 students ? 29 girls and 15 boys, 17?20 years old. There was used immunosorbent assay to determine the level of cortisol and testosterone during tredmil-test, estimated on maximal aerobic power. Results: the relationship between the imbalance between cortisol and testosterone at an altitude under stress test in young people with low tolerance to physical activity in favor of cortisol. Conclusions: reduced tolerance to exercise, accompanied by high cortisol and testosterone index, decreased maximal aerobic power and tolerance.
