Yoga respiratory exercises consisted of rapidly forced expirations followed by inspiration through the right nostril, inspiratory apnoea with the generation of intrathoracic negative pressure, and expiration through the left nostril may have a strong and positive effect in enhanced pulmonary function, some institute studies suggested.
Yoga, the ancient practice for harmonized external and internal body well beings, through breath control, meditation, bodily movement, and gesture..... has been best known for people in the Western world and some parts in Asia due to health benefits reported by various respectable institutes' research and supported by health advocates.
In a review of literature published on the database from Alternative Health Watch, the Physical Education Index, Medline,(®) and the SPORTdiscus to investigate the effect of yoga in increased lung function of healthy individuals, researchers found that most studies expressed an overall improvement of yoga intervention in lung function measured by maximum inspiratory pressure, maximum expiratory pressure, maximum voluntary ventilation, forced vital capacity, forced expiratory volume in 1 second, and peak expiratory flow rate.
Maximum inspiratory pressure is a marker of respiratory muscle function and strength generated against an occluded airway beginning at the volume of air present in the lungs at the end of passive expiration.
Maximum expiratory pressure is a measure attained by a patient attempting to exhale into a closed system.
Maximum voluntary ventilation (MVV) is a measure of a maximum of air inhaled and exhaled within one minute.
Forced vital capacity (FVC) is the amount of air forcibly exhaled from the lungs after taking the deepest breath.
Forced expiratory volume (FEV) is a measurement of air a person can exhale after taking a forced breath.
Peak expiratory flow rate is a measurement of a maximum speed of expiration, measured by a peak flow meter,
After taking into account of other confounders, researchers emphasized
1. The positive effect of lung function can only be achieved with a yoga class offered at least 10 weeks practicing yoga breathing exercises.
2. Interestingly enough, less-fit individuals showed greater improvements in pulmonary functioning compared to healthy individuals
3. Greater achievement also depended in length of yoga engagement
Other researchers in support of yoga exercise in improved lung function also conducted a prospective open-label study of patients with a confirmed diagnosis of Duchenne muscular dystrophy (DMD), recruited from among those followed at the neurology outpatient clinic of a university hospital in the city of São Paulo, Brazil. randomized assigned to breathing exercises three times a day for 10 months, found that in 26 completed the study, yoga breathing exercises resulted in a significant increase in airway resistance in (FVC) and the first measurement of Forced Expiratory Volume (FEV1).
Airway resistance in the rate of (FEV1/FVC) measured by spirometry is much lower in patients with the pulmonary disease compared to healthy individuals.
More importantly, in the study to compare pulmonary functions and diffusion capacity in patients of bronchial asthma before and after yogic intervention of 2 months with 60 stable asthmatic-patients randomized into two groups i.e group 1 (Yoga training group, n=30) and group 2 (control group, n=30), researchers after taking into account of other confounders filed the following results
1. Yoga group showed a significant effect in overall lung function improvement, according to the assays in Transfer factor of the lung for carbon monoxide (TLCO), forced vital capacity (FVC), forced expiratory volume in 1st sec (FEV1), peak expiratory flow rate (PEFR), maximum voluntary ventilation (MVV) and slow vital capacity (SVC) in compared to control
2. Yoga participated group also improved quality of life
Dr. Singh S, the led author said, "pranayama & yoga breathing and stretching postures are used to increase respiratory stamina, relax the chest muscles, expand the lungs, raise energy levels, and calm the body".
Taking all together, tt is safe to recommend yoga as a secondary therapeutic therapy combined with standard treatment in improved pulmonary functions in healthy individuals and patients with pulmonary disease.
