Introduction: Sedentary lifestyle has given rise to various lifestyle diseases. Regular exercise training is known to improve cardiovascular functions. Heart rate variability analysis is done to assess cardiac autonomic function. The present study is to assess and compare heart rate variability in trained athletes and sedentary individuals.
Materials and Methods: A cross sectional study, matched for age and sex, was done in 30 apparently healthy trained athletes and 30 apparently healthy sedentary individuals. BMI, resting pulse, blood pressure and heart rate variability analysis was done and analysed statistically.
Results: In trained athletes; parameters of heart rate variability RMSSD (Root Mean Sum of Square Difference), Low Frequency (LF) and High Frequency (HF) showed significant increase and Resting pulse rate and Diastolic blood pressure showed significant decrease as compared to sedentary individuals.
Conclusion: Heart rate variability is increased in trained athletes than sedentary individuals.

Keywords: Heart rate variability, Trained Athletes, Sedentary individuals.
