Background: Ananda Yoga is a system of yoga practice based on the teachings of great yoga master Paramhansa Yogananda that includes different yoga modalities like– Energization Exercises, Yoga Postures, Pranayama and Meditation.

Aim: To study the effects of different modalities of Ananda Yoga on cardiac autonomic modulation and on subjective wellbeing.

Method: 25 yoga naive subjects with mean age36.84±10.12yrs were enrolled. A questionnaire based subjective wellbeing and high sampled ECG was recorded for heart rate variability (HRV) analysis.

Results: Compared to resting baseline all HRV parameters (SDNN, LF (ms²), HF(ms²), Average Heart Rate ) showed statistically significant modulation in  different yoga modalities (p value<0.05).

Conclusion: Different modalities of Ananda Yoga were found to affect cardiac autonomic modulation and subjective wellbeing of the participants. Large multi centre trials are needed to further explore these results.
