  Author(s): Athira Surendran* and Shreesh Ajaykumar
  
  Background: Sympathetic activity in obesity-related cardiovascular diseases indicates the association between cardiac autonomic functions and BMI (Body Mass Index). The Heart Rate Variability (HRV) is considered as an appropriate measure of cardiac autonomic function. A stressor, like an exercise, requires changes in the neural, cardiovascular and autonomic control that are unique to the person. So the study was conducted to assess the heart rate variability of normal and overweight individuals during the pre-and post-exercise period. Methods: A case-control study with 42 subjects of 17-25 years old was done. Subject with their BMI ≥ 25 kg/m2 (overweight) was taken as cases and their BMI within normal limits (18.5 kg/m2-24.9 kg/m2) was taken as controls. Resting HRV was recorded. Then, the subjects were asked to perform Harvard Step Test and the post-exercise HRV was recorded immed.. Read More»
