The state of cardiorespiratory system in female students with idiopathic arterial hypertension under treadmill training

Abstract

Annotation. One of the most widespread pathogenic condition, among young women, is idiopathic arterial hypertension which significantly worsen the life condition, learning abilities and in future can lead to the development of arterial hypertension, ischemic heart disease, complicate course of the pregnancy and delivery. The aim of the research was to examine the functional state of cardiorespiratory system in female students of 1-3rd year of high school with the signs of idiopathic arterial hypertension under the fixed stress- test. The main group consisted of 32 female students of 1-3rd year of high school with idiopathic arterial hypertension. The control group was formed from almost healthy female students from the same years of study. The treadmill (Biomedical Systems), due to Bruce protocol, was used for estimating the level of tolerance to physical pressure. To assess the degree of reliability of the results of the study used a variational-statistical method of analysis of the results using a package of statistical programs Statistica V. 10 (USA) and the recommendations of O. Yu. Rebrova (2002). Under the treadmill test it was revealed the decrease of tolerance to physical pressure in female students from the main group on 31,24% (р<0,05), in comparison to the MET numbers got in the control group (37,11±2,16) ml/kg/min. Under stress-test reliable increase of heart rate in control group was observed after 6-8 minutes of training, in female students from control group the same reaction was observed after 3-5 min of training without its further increase. The increase of SBP in the main group at the peak of training was (20,88±3,12)%, in the control group – this index was completely higher (27,88±3,36)% (р<0,01). After the finishing of the stress test in the female students of the main group the duration of their heart rhythm and arterial pressure reviving was (9,85±1,22) min., that overcame the result got in control group (6,24±0,67) min. Thus, the treadmill test allows exactly reveal the level of cardiorespiratory system adaptation to physical pressure, aerobic capacity in young women with the signs of idiopathic arterial hypertension.
