The Relationship between Heart Rhythm Variability and the Heart Rate in Adolescents and Young Adults
In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability of the ...
Young ‘s body mass index and its im¬pact on the frequency and variability of the heart rhythm at quiet and after phy¬sical load
A medical examination on a selected group of young people demonstrated a negative correlation between the body mass index and the heart rate at rest, which disappeared after some physical activity. Physical activity was observed to change the heart rate variability under the influence of the changes magnitude in the initial heart rate. No correlation between body mass index and heart ...
Comparison of heart rate parameters in students with different achievements in rest and conditions of short-term mental stress
Frequency and variability of heart rate served as instruments to assess the stress resistance of two groups of students with different average academic performance in different periods of the educational process: at the beginning and at the end of the autumn semester. Mental stress always ...
