Background: It has been shown in athletes the maximum systolic blood pressure (SBP) in physical activity depends on gender and it is 220 mmHg among men and 200 mmHg among women (Caselli S, 2016). In children the value of SBP depends on height. But this aspect does not consider at the load. Propose: to determine the BP in young elite athletes depending on height. Methods: we examined 2305 (age 16±1.3 years, 45% men) young elite athletes of the members of the National teams with normal BP at the rest. The men's height was 179±13 cm and women's 168±10 cm. All of them were conducted bicycle ergometry using the PWC170 protocol with an initial load of 1 W/kg with a subsequent load increase every 3 minutes by 25 W until the pulse 170 bpm or physical fatigue. BP was measured manually at maximum load. Results: The tolerance of physical exercise in men was higher than in women (2.5±0.4 W/kg vs 2.2±0.4 W/kg, p<0.001). The maximum heart rate (HR) were reached in 38% (873, 41% men), 62% did not reach it, there HR - 155±11 bpm in men and 154±11 bpm in women. The values of the maximum BP were significantly higher in men: SBP 195±25 vs 175±20 mmHg, p<0.001; diastolic blood pressure (DBP) 80±11 vs 80±10 mmHg, p<0.05. We revealed correlations between BP at height (SBP: r=0.55, p<0.001; DBP: r=0.18, p<0.001). The percentile values of the maximum SBP in young elite athletes depending on height presented in table. Conclusion: In young elite athletes the maximum value of BP during physical activity depends not only on gender, but also on height.
