Cardio-respiratory endurance of individuals with different blood pressure levels

Abstract

Evaluation of cardio-respiratory endurance in individuals with different levels of blood pressure is one of the key factors in preventing the development of diseases of the cardiovascular system. The purpose of the study was to conduct a comparative assessment of cardio-respiratory endurance, the level of maximum oxygen consumption, and the results of the Ruffier test in individuals with different blood pressure levels. 320 people were examined, of which 4 groups were formed according to the initial level of blood pressure. After measuring baseline blood pressure and heart rate, all subjects underwent a Ruffier test (30 sit-ups for 45 seconds), followed by repeated heart rate measurements at 15 seconds, 1 minute, and blood pressure measurements at 3 minutes. Determination of the level of maximum oxygen consumption was performed according to the formula. Representatives of the group with normal-low and normal blood pressure have a significantly higher level of maximum oxygen consumption. Individuals with normal-high blood pressure and first-degree hypertension had higher levels of systolic and diastolic blood pressure during daily blood pressure monitoring, both during the day and at night, compared to individuals with normal and normal-low blood pressure. It was established that people with normal-low blood pressure have a higher cardio-respiratory endurance than people with normal-high blood pressure and first-degree hypertension. The findings of the study can be used by cardiologists and general practitioners for early detection and prevention of diseases of the cardiovascular system, and physiologists in further investigation of the features of the functioning of the cardiovascular system
