The aim of the present study is to highlight the beneficial effects of yoga practice on bio-parameters, such as oxidative stress, antioxidant components, immune functions, and secretion of stress hormones, in healthy young people.
This study was conducted on healthy volunteers recruited from among university students, who were divided into two groups: a control (no yoga intervention, n=13) group and a yoga (n=12) group. Yoga practice was with an instructor for 90 minutes once a week spread over 12 weeks, with recommendations to practice daily at home for 40 minutes with the help of a DVD. The yoga program consisted of yoga body poses (asanas), exercises involving awareness, voluntary regulation of breath (pranayama), and meditational practices. Whole blood samples were collected when the volunteers had fasted for 8 hours at 0 and 12 weeks. The oxidative stress/antioxidant components, immune-related cytokines, and stress hormones were evaluated in serum or plasma.
Serum levels of nitric oxide, F2-isoprostane, and lipid peroxide were significantly decreased by yoga practice (p<0.05 or p=0.01), whereas serum total glutathione (GSH) contents, activities of GSH-peroxidase, and GSH-s-transferase were remarkably increased after yoga practice compared with the control group (p<0.05 or p=0.01). Yoga practice also significantly increased immune-related cytokines, such as interleukin-12, and interferon-γ, in serum (p<0.05 or p=0.01). Yoga practice significantly reduced the plasma levels of adrenalin (p<0.05) and increased plasma levels of serotonin compared with the control group (p<0.05).
Regular yoga practice remarkably attenuated oxidative stress and improved antioxidant levels of the body. Moreover, yoga beneficially affected stress hormone releases as well as partially improved immune function.
本研究旨在强调瑜伽练习对健康年轻人生物参数的有益影响，如氧化应激、抗氧化成分、免疫功能和应激激素分泌。
本研究对从大学生中招募的健康志愿者进行，将他们分为两组：对照组（无瑜伽干预，n = 13）和瑜伽组（n = 12）。瑜伽练习由一名教练指导，每周一次，每次90分钟，持续12周，并建议在家借助DVD每天练习40分钟。瑜伽课程包括瑜伽体式（体式）、涉及意识的练习、呼吸的自主调节（调息）和冥想练习。在0周和12周时，当志愿者禁食8小时后采集全血样本。对血清或血浆中的氧化应激/抗氧化成分、免疫相关细胞因子和应激激素进行评估。
瑜伽练习使血清一氧化氮、F2-异前列腺素和脂质过氧化物水平显著降低（p<0.05或p = 0.01），而与对照组相比，瑜伽练习后血清总谷胱甘肽（GSH）含量、GSH-过氧化物酶和GSH-s-转移酶活性显著增加（p<0.05或p = 0.01）。瑜伽练习还显著增加了血清中免疫相关细胞因子，如白细胞介素-12和干扰素-γ的水平（p<0.05或p = 0.01）。与对照组相比，瑜伽练习显著降低了血浆肾上腺素水平（p<0.05），并增加了血浆血清素水平（p<0.05）。
定期进行瑜伽练习可显著减轻氧化应激并提高身体抗氧化水平。此外，瑜伽对应激激素释放有有益影响，并部分改善了免疫功能。
