Studies showing the impact of MBTs.

Study	Sample Size & Treatment Groups	Interventions	Targeted Output	Outcome Measurements	Findings
Bernardi et al. 2001	n = 19; 10 yoga trainees and 9 controls	Slow yogic Breathing	Blood oxidation and sympathetic system	minute ventilation (VE), oxygen saturation, RR interval, blood pressure and response to carotid baroreceptors at baseline and after acute hypobaric hypoxia	Slow yogic breathing maintains better blood oxygenation and reduces sympathetic activation in hypoxic conditions
Bernardi et al. 2007	n = 75; 12 Caucasian yoga trainees, 12 control sea-level residents, 38 active lifestyle high altitude natives and 13 high altitude residents performing yoga like respiratory exercises	Yoga	Ventilatory, cardiovascular and hematological parameters	hypoxic ventilatory response (HVR), red blood cell count, hematocrit, blood pressure, RR interval, minute ventilation	Yoga pre-conditioning leads to few hematological changes, maintains oxygen and induces respiratory adaptations to cope up with altitude-induced hypoxia in sea-level residents
Bilo et al. 2012	n = 67; 39 at 4559 m and 28 at 5440 m	Slow deep breathing	Oxygen saturation, pulmonary and systemic hemodynamics	Minute ventilation or pulmonary CO diffusion, Spo2, systematic, and pulmonary arterial pressure	Slow deep breathing increases SpO2, which improves ventilation efficiency and reduces systematic and pulmonary arterial pressure at high altitude
Himashree et al. 2016	n = 200 Indian army soldiers; 100 performed physical training and 100 Yoga at 3445 m	Yoga	Physiological and biochemical status	Height and Weight, body fat percentage, heart rate, respiratory rate, systolic and diastolic blood pressure, peripheral saturation of oxygen, end tidal CO2, pulmonary functions, hematological variables lipid profile serum urea, creatinine, liver enzymes, blood glucose, and anxiety scores.	Significant improvement in health indices and performance was observed in yoga group as compared to control group at high altitude
