At present, there are no generally accepted normative values for blood pressure (BP) in athletes under exertion. Objective: to determine the normative parameters of blood pressure in young elite athletes in a test with dosed physical activity. 500 (229 girls and 271 boys) young elite athletes of 14–17 (15.8 ± 1.5) years old were examined, members of the youth teams of the Russian Federation, different in static and dynamic sports. The control group consisted of 36 healthy adolescents of the same age who are not involved in sports. All subjects underwent bicycle ergometry according to the PWC 170 protocol with an initial load of 1 W/kg, followed by an increase in load every 3 minutes by 25 W until a pulse of 170 bpm was reached or fatigue, blood pressure was measured manually according to the method of N. S. Korotkov at the end of each stage of the load. For young elite athletes, the maximum values of systolic blood pressure (SBP) on the load were significantly higher than for their peers who were not involved in sports (185 ± 20 vs 154 ± 15 mm Hg; p < 0.001). In a sample with dosed physical activity, the parameters of the SBP in young elite athletes can reach up to 230 mm Hg with an adequate increase in heart rate (heart rate ≥ 170 bpm.).
