Eleven patients with severe chronic airways obstruction were given training in yogic breathing exercises and postures. A matched group of 11 patients were given physiotherapy breathing exercises. Both groups of patients were followed up at monthly intervals for nine months with pulmonary function tests, tests of exercise tolerance, and inquiry into their symptoms. After training in yoga the mean maximum work increased significantly by 60.55 kpm; whereas no such rise occurred after training in physiotherapy. This objective improvement was associated with symptomatic improvement in a significantly higher number of patients given training in yoga.
Twenty Type 2 diabetic subjects between theage group of 30-60 years were studied to see the effect of 40 days of <i style="">Yoga</i> <i style="">asanas</i>
on biochemical profile. The duration of diabetes ranged from 0 to 10 years.
Subjects suffering from cardiac, renal and proliferative retinal complications
were excluded from the study. <i style="">Yoga</i> <i style="">asanas</i> included <i style="">Surya Namaskar</i>, <i style="">Tadasan</i>, <i style="">Konasan</i>, <i style="">Padmasan</i>, <i style="">Pranayama</i>, <i style="">Paschimottanasan</i>, <i style="">Ardhmatsyendrasan</i>, <i style="">Shavasan</i>,
<i style="">Pavanmuktasan</i>, <i style="">Sarpasan</i> and <i style="">Shavasan</i>.
Subjects were called to the cardio-respiratory laboratory in the morning time
and were given training by the <i style="">Yoga</i>
expert. The <i style="">Yogic</i> exercises were
performed for 30 - 40 minutes every day for 40 days in the above sequence. The
subjects were prescribed medicines and diet. The basal blood glucose, lipid
profile and glycosylated haemoglobin was measured and repeated after 40 days of
<i style="">yoga asanas</i>. There was a statistically
significant decrease in fasting blood glucose (from baseline 208.3 ± 20.0 to 171.7 ± 19.5
mg/dl) and decrease in Postprandial blood glucose (from 295.3 ± 22.0 to 269.7± 19.9
mg/dl). The decreases in values of serum cholesterol were also statistically
significant (from 222.8 ± 10.2 to
207.9 ± 8.6 mg/dl). The triglyceride decreased
(from 168.5 ± 15.5 to 146.3 ±13.5 mg/dl), low-density lipoprotein cholesterol and very
low-density lipoprotein improved (from 144.8 ± 8.6 to 140.70 ± 7.9
mg/dl and from 37.4 ± 4.6 to
32.1 ± 3.4 mg/dl). The glycosylated
haemoglobin decreased from 10.27 ±0.5 to
8.68 ± 0.4 %. These findings suggest that <i style="">yoga asanas</i> have a beneficial effect on
glycaemic control and lipid profile in mild to moderate Type 2 diabetes.
Prana is the energy, when the self-energizing force embraces the body with extension and expansion and control, it is pranayama. It may affect the milieu at the bronchioles and the alveoli particularly at the alveolo-capillary membrane to facilitate diffusion and transport of gases. It may also increase oxygenation at tissue level. Aim of our study is to compare pulmonary functions and diffusion capacity in patients of bronchial asthma before and after yogic intervention of 2 months. Sixty stable asthmatic-patients were randomized into two groups i.e group 1 (Yoga training group) and group 2 (control group). Each group included thirty patients. Lung functions were recorded on all patients at baseline, and then after two months. Group 1 subjects showed a statistically significant improvement (P<0.001) 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) after yoga practice. Quality of life also increased significantly. It was concluded that 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.
OBJECTIVES: 1. To study the effect of forty days of Yogic exercises on cardiac functions in Type 2 Diabetics. 2. To study the effect of forty days of Yogic exercises on blood glucose level, glycosylated hemoglobin. METHODS: The present study done in twenty-four Type 2 DM cases provides metabolic and clinical evidence of improvement in glycaemic control and autonomic functions. These middle-aged subjects were type II diabetics on antihyperglycaemic and dietary regimen. Their baseline fasting and postprandial blood glucose and glycosylated Hb were monitored along with autonomic function studies. The expert gave these patients training in yoga asanas and they pursued those 30-40 min/day for 40 days under guidance. These asanas consisted of 13 well known postures, done in a sequence. After 40 days of yoga asanas regimen, the parameters were repeated. RESULTS: The results indicate that there was significant decrease in fasting blood glucose levels from basal 190.08 +/- 18.54 in mg/dl to 141.5 +/- 16.3 in mg/dl after yoga regimen. The post prandial blood glucose levels decreased from 276.54 +/- 20.62 in mg/dl to 201.75 +/- 21.24 in mg/dl, glycosylated hemoglobin showed a decrease from 9.03 +/- 0.29% to 7.83 +/- 0.53% after yoga regimen. The pulse rate, systolic and diastolic blood pressure decreased significantly (from 86.45 +/- 2.0 to 77.65 +/- 2.5 pulse/min, from 142.0 +/- 3.9 to 126.0 +/- 3.2 mm of Hg and from 86.7 +/- 2.5 mm of Hg to 75.5 +/- 2.1 mm of Hg after yoga regimen respectively). Corrected QT interval (QTc) decreased from 0.42 +/- 0.0 to 0.40 +/- 0.0. CONCLUSION: These findings suggest that better glycaemic control and stable autonomic functions can be obtained in Type 2 DM cases with yoga asanas and pranayama. The exact mechanism as to how these postures and controlled breathing interact with somato-neuro-endocrine mechanism affecting metabolic and autonomic functions remains to be worked out.
