ABSTRACT
OBJECTIVES: Imprisoned people usually have a poor health status and an increase risk to suffer chronic debilitating conditions, co-infection due to their limitations in physical activity and mental disturbances. This study was carried to find out the health impacts of Yogic practice of Indian healthy jail inmates. METHODS: It was interventional single group pre-post design study. A total no of 30, Jail inmates including 08 female were participated in this study and practiced Yoga for six months. Body Mass Index, Heart Rate, Blood Pressure, Salivary alpha amylase activity (SAA) a stress marker were assessed before, after three months and after completion of six months of Yogic practice. RESULTS: Improvement was noted in all parameters, but significant improvement was noted in systolic blood pressure, diastolic blood pressure, mean blood pressure, double product a index of load in the heart and SAA following Yogic practice in total participants. Significant improvement was also noted in systolic blood pressure, diastolic blood pressure, mean blood pressure, double product a index of load in the heart and SAA following Yogic practice in male group. No significant effect was noted in female group. CONCLUSIONS: The present study revealed that regular Yogic practice resulted in reduction blood pressure, load in the heart and stress in mail jail inmates, when it is practiced regularly and carefully.
ABSTRACT
Background Many clinical trials have evaluated the oxidative stress reduction and enhancement of antioxidant status following yogic practices, but a review has not been reported earlier. Present study is designed to systematically review the effect of yogic practices on oxidative stress and antioxidant status. Content Using the MEDLINE, EMBASE SCOPEMED, and Indian database electronic searches were performed through August 2016 using the keywords yoga AND oxidative stress OR antioxidant which yielded 97 studies. Selections were made to include only experimental studies written in English, published in peer-reviewed journals and investigating the effects of regular yogic practices on oxidative stress and antioxidant status in these studies. Summary and outlook Search yielded a total of 97 trials, 11 met rigorous criteria for final systematic review. Healthy population showed overall enhancement of antioxidant status and reduced oxidative stress following yogic practices. Diabetic patients showed increased glutathione, vitamin C content and superoxide dismutase activity and decreased malondialdehyde content following yogic practices. Prediabetic and hypertensive patients showed reduced malondialdehyde content following yogic practices. Renal disease patients showed decreased protein oxidation, and increased superoxide dismutase activity following yogic practices. Regular yogic practices can improve antioxidants and reduce oxidative stress in healthy, diabetic, prediabetic, hypertensive and renal disease patients. Studies on other disease population have rarely been reported and studies are very few to conclude strongly.
ABSTRACT
BACKGROUND: This study was conducted to evaluate the effects of yogic practice on resting metabolism and redox status. METHODS: The study was conducted on 64 physically trained male volunteers selected randomly at the Air Force Academy. The yoga group (n = 34) practiced yogasana, pranayama, and meditation for 3 months (February-May 2011) and the control group (n = 30) performed physical training. Antioxidant variables in blood samples along with physiological parameters were estimated before and after 3 months. RESULTS: No significant difference was noted between baseline data of the control group and yoga group. Reduced glutathione, vitamin C, and vitamin E; the ratio of reduced to oxidized glutathione; and total antioxidant status were increased significantly following yogic practice. Activities of superoxide dismutase, glutathione S-transferase, and glutathione reductase were significantly increased, whereas activity of glutathione peroxidase was significantly decreased following yogic practice. Oxidized glutathione decreased significantly following yogic practice. A nonsignificant decrease of hydroperoxides, protein carbonyl, malondialdehyde, and blood sugar was noted in the yoga group. Carbon dioxide elimination and peripheral oxygen saturation increased significantly following yogic practice. No significant changes were observed in the control group following 3 months of physical training. CONCLUSIONS: Regular yogic practice can improve resting metabolism and redox status of the practitioner.

Aging is associated with decline in cardiovascular, autonomic function, and brain-derived neurotropic factor (BDNF). Reports are scanty regarding whether yoga can improve age-related degenerative changes in healthy active men. This study is designed to appraise the role of yoga in improving age-related degenerative changes in cardiometabolic risk profile, autonomic function, stress, and BDNF. Healthy active males of three age groups (20-29, 30-39, and 40-49 years) were randomly assigned to practice yoga daily 1 h for 3 months. Significantly higher values of heart rate (HR), blood pressure (BP), load in heart (DoP), myocardial oxygen consumption (RPP), and total cholesterol (TC) were noted in senior age group. HR, BP, DoP, RPP, and TC decreased significantly following yogic practice. High frequency (HF), total power (TP), all time domain variables of heart rate variability (HRV), and skin conductance (SC) were significantly decreased with advancement of age. HF, TP, and time domain parameters of HRV and SC increased significantly following yogic practice. Higher levels of catecholamines and low frequency (LF) power of HRV was noted with advancement of age. Levels of catecholamines and LF significantly decreased following yogic practice. Cortisol and adrenocorticotropic hormone (ACTH) level raised in senior age group. BDNF, serotonin, and dopamine were low in higher age group. Significant decrement of cortisol; ACTH; and increment in serotonin, dopamine, and BDNF was noted following yogic practice. This study revealed that yogic practices might help in the prevention of age-related degeneration by changing cardiometabolic risk factors, autonomic function, and BDNF in healthy male.
