| The test groups (when compared with the control group and with themselves before practice) will have better emotional and attentional regulation; Such a comparison will be made based on the following methodological approaches: i) apply psychometric scales in terms of personality neuro-affective, interoceptive sensitivity, sleep quality, anxiety, perceived stress, mood, excessive mind wandering and impulsivity; ii) investigate the ability to focus / concentrate and to emotional self-regulation through the post-test Flanker attentional task of stress induction (Mannheim multicomponent stress test or MMST); iii) analyze physiological parameters such as electroencephalogram, electrocardiogram, optoelectronic plethysmography, blood pressure measurement and inspiratory drive and iv) quantify the levels of salivary cortisol upon awakening and mBDNF and cortisol plasmatic.;The test groups (when compared with the control group and with themselves before practice) will have a higher spectral power density of beta and gamma oscillations and a lower alpha wave in the prefrontal cortex;;The test groups (when compared with the control group and with themselves before practice) will have significant respiratory neuroplasticity;;The test groups (when compared with the control group and with themselves before practice) will have a more abdominal than thoracic breathing pattern;;The test groups (when compared with the control group and with themselves before practice) will have greater heart rate variability (indicative of parasympathetic domain);;The test groups (when compared with the control group and with themselves before practice) will have reduced levels of salivary and blood cortisol and increased levels of blood mBDNF;;Regarding the difference between the two breathing techniques, we assume that the Nadi Shodhana group will perform better in the attentional task than the Ujjayi group over the 90 days of practice and that the latter will obtain better parameters of respirat | — |
