Yoga training study design. The study design comprised a total duration of 22 min and 20 s and was divided into distinct phases. The initial phase consisted of prerecording (blue color) with the eyes closed, lasting 2 min and 40 s, which captured baseline measurements prior to yoga training. Following this, participants engaged in a 15-minute session of yoga training (green color), a series of 12 postures performed in a flowing sequence as in pictorial representation. After the training, there was a 2-minute break (gray color) to allow the participants to rest. Finally, a post-yoga recording (pink color) of 2 min and 40 s was conducted with the participants’ eyes closed. This process was repeated for all 39 trials (3 trials each on 13 subjects).
