Diagnostics of arterial vessels of athletes using Doppler ultrasound measurement

Abstract

Objectives: The volumetric blood flow of arterial vessels of athletes with a high sports category was studied using the Doppler ultrasound measurement. Methods: Two groups of volunteers were examined: group I consisted of unsportsmanlike volunteers who do not suffer from cardiovascular pathology, and group II consisted of athletes who have the rank of candidate master of sports. The diagnosis was carried out based on the results of measuring the arterial blood flow rate in conditions of reactive hyperemia of the brachial artery and in relation to the reverse volumetric blood flow to the volumetric systolic blood flow. Results: A comparative analysis of changes in the ultrasound Dopplerograms of athletes and untrained volunteers indicates a significant difference in both the peak velocity of the arterial blood flow in the conditions of reactive hyperemia of the brachial artery. Another method of registering the altered state of arterial vessels in athletes may be the ratio of the volume velocity of the reverse blood flow to the volume velocity of the systolic blood flow. Conclusion: The method of ultrasonic Dopplerography for the diagnosis of arterial vascular of athletes with a high sports category has been proposed. The measurements have shown that the ratio of the volumetric velocity of the reverse blood flow to the volumetric velocity of the systolic blood flow is significantly higher in athletes.
