HEART RATE VARIABILITY DURING TEMPORARY OCCLUSION OF THE LOWER EXTREMITIES IN ATHLETES
Main Article Content
Abstract
Introduction. Temporary occlusion of the lower extremities is an accessible model of short-term ischemia that allows controlled physiological stress to be reproduced without significant health risks. It is accompanied by the activation of peripheral and central mechanisms of blood circulation regulation, changes in vascular tone, and affects the functioning of the cardiovascular system. Studying the response of heart rate variability to such changes provides an opportunity to gain a deeper understanding of the mechanisms of its adaptation to short-term ischemic influences.
Objective. To determine the characteristics of heart rate variability indicators at different levels of temporary occlusion of the lower extremities in students majoring in physical education and sports..
Methods of the study. Measurements were taken on 30 men aged 18-25 years - students of physical education and sports specialties. Occlusive effects were performed on the thighs with a 200 mm wide blood pressure cuff for 3 minutes. The intensity of the first impact was the level of diastolic pressure + 50 mm Hg; the second was the level of systolic pressure + 50 mm Hg. Heart rate variability indicators were recorded and calculated using the Polar Protrainer 5.0 program.
Main results of the study. Venous occlusion did not cause significant changes in the time indicators of heart rate variability, while arterial occlusion caused changes in these indicators from the 1st to the 10th minute of recovery. The greatest increase was in rMSSD as a marker of increased tone of the parasympathetic division of the autonomic nervous system. Analysis of the coefficients of variation in HRV reactivity showed that their level was significantly higher at 1 and 10 minutes after venous occlusion than in the corresponding periods after arterial occlusion. This may indicate the presence of more pronounced individual adaptations of heart rate regulation during venous occlusion compared to arterial occlusion. Analysis of changes in HRV spectral indicators showed a significant increase in parasympathetic influences on heart activity during arterial occlusion.
Scientific novelty of the study results. For the first time, a comparative analysis of the effects of short-term venous and arterial occlusion on heart rate variability in healthy individuals - students majoring in physical education and sports - was conducted.
Conclusions and specific suggestions of the author. The study opens up new opportunities for the differentiated impact of lower limb occlusion on the functional state of individuals engaged in physical culture and sports.
