HEART RATE MONITORING OF OVERWEIGHT AND UNDERWEIGHT YOUNG SUBJECTS

Abstract

Background: Excessive adipose tissue mass is referred to as obesity, and it is typically measured by body mass index, or 
BMI. One test used to evaluate the impact of autonomic control on the heart is heart rate variability, or HRV.  
Aim: The purpose of this study was to evaluate the heart rate variability of young volunteers who were overweight (BMI >25 
kg/m2) and underweight (BMI <18 kg/m2), respectively. 
Methods: In order to measure changes in heart rate variability in young people as determined by body weight, the current 
study comprised participants ages 18 to 25. Anthropometric measures including blood pressure, resting pulse rate, and 5
minute supine heart rate variability were measured in each participant from both groups. In two groups, the effects of body 
weight on heart rate variability were assessed and contrasted. 
Results: According to the study's findings, subjects in the overweight group had significantly lower levels of the following: 
TP (total power), SDNN (standard deviation of NN interval), HF (high frequency), RMSSD (square root of mean squared 
difference of successive NN interval), and LFnu. The study's findings also revealed a noteworthy inverse relationship between 
the two study groups' HFnu, LFnu, and RP (resting pulse).  
Conclusions: According to the current study, overweight group individuals have autonomic dysfunction, which can lead to 
early heart-related issues. This dysfunction is defined by a decrease in parasympathetic and an increase in sympathetic activity.
