Key result
Therapeutic yoga practice altered heart rate variability, increasing MHR, LF/HF, and SD1/SD2 during postures and decreasing them during rest, while pNN50 showed the opposite pattern.
Why the study?
Practicing yoga has become effective across age groups, but research focusing on movement-related yoga postures remains limited.
Does therapeutic yoga practice affect physiological biosignals (ECG, EMG, HRV) differently in yoga trainers compared to untrained subjects?

Does therapeutic yoga practice affect physiological biosignals (ECG, EMG, HRV) differently in yoga trainers compared to untrained subjects?
Therapeutic yoga postures induce measurable changes in heart rate variability and physiological signals, with distinct patterns during active postures versus rest.
Acute HRV shifts during yoga postures may indicate autonomic responses; hypothesis-generating for training-status differences and clinical relevance.
Practicing yoga has become more effective among all kind of age groups, but researches focusing on the movement related yoga postures are limited. This work analysis the effect of therapeutic yoga on biosignals. Physiological parameter variations between yoga trainers and untrained subjects while performing the selected asanas including pranayama, dwipadapitham, apanasana, jathara parivrtti has been studied. ECG and EMG are acquired simultaneously before, during and after the specially framed yoga practice sequence. These signals are processed suitably to measure the time and frequency domain features and analyze their variations over the period of recording. HRV analysis shows variation of MHR, LF/HF and SD1/SD2 with increase during posture and decrease with rest. pNN50 shows decrease during posture and increase during rest. Further study will helpful in designing special yoga course for individuals based on their requirements and thus complementing their medical support as well.

Praba et al. (2020) reported an observational. Therapeutic yoga practice vs. Untrained subjects / Rest was evaluated on Heart rate variability (HRV) parameters including MHR, LF/HF, SD1/SD2, and pNN50. Therapeutic yoga practice altered heart rate variability, increasing MHR, LF/HF, and SD1/SD2 during postures and decreasing them during rest, while pNN50 showed the opposite pattern.
