Effects of Yogic Practice on Metabolism and Antioxidant - Redox Status of Physically Active Males.

BACKGROUND:
To evaluate the effects of yogic practice on resting metabolism and redox status.
METHODS:
Study was conducted on 64 physically trained male volunteers selected randomly at Airforce Academy, Dundigal. The yoga group (n = 34) practiced yogasana, pranayama and meditation for 3 months (February - May 2011) and 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 control group and yoga group. Reduced glutathione, vitamin C, 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 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.
