Introduction: Obesity is a condition from which the body has an excess accumulation of fat, which may cause from current daily routines and activities such as overeating and/or lacking of exercise. Nutritional problem in India is shifting from undernourishment to obesity. The autonomic nervous system plays an important role, not only in physiological situations, but also in various pathological settings such as diabetic neuropathy, myocardial infarction and congestive heart failure. Materials and Method: This study consists of 100 healthy young adults and 100 subjects in the age group of 20-26 years selected from the patient attendants and medical students of Santosh Medical College and Research Centre, Ghaziabad. Anthropometric parameters like height and weight were recorded. Body Mass Index (BMI) was calculated. They were categorized as Cases (n=100) and Controls (n=100) based on the BMI, Controls whose BMI < 25kg/m2 and Cases with BMI > 30kg/m2. Subject was explained in detail about the ongoing procedure and ECG was digitally recorded after 10 minutes rest using lead II. Results: The mean age of the controls and cases were 22.16 and 21.82 respectively. Our study results showed significant inverse relationship between BMI and HRV parameters like SDNN, E/I ratio and HF nu, but at the same it showed significant positive relation of BMI and LF nu, LF/HF. Conclusion: The present findings demonstrate decreased HRV is associated with age, male gender and increased heart rate. Keywords: Obesity, Exercise, Nutritional, Heart Rate
