Title: Effects of Yoga practice on oxidative stress biomarkers: Systematic review and meta-analysis Background: The main objective of this paper is to assess whether continuous Yoga practice exerts any change in the concentrations of oxidative stress biomarkers and enzymes. antioxidants. The specific objectives are, first, to describe the characteristics of the included studies; secondly, to carry out a quantitative synthesis with the studies included in the systematic review; third, to assess the risk of bias of the included studies. Method: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used as a methodological guide for the publication of the research. The eligibility criteria used were the following: i) randomized controlled clinical trials from any country and in any language, ii) studies that quantify at least one biomarker selected for this work (reactive oxygen species, substances reactive to thiobarbituric acid , malondialdehyde, nitric oxide, superoxide dismutase, glutathione, catalase), iii) studies carried out in people over 18 years of age with or without comorbidities, iv) studies that have a yoga group and a control group, v) studies that report the practice of yoga for at least 21 days. The collection of studies was carried out by searching electronic databases such as PubMed, Scopus, Web of Science, Embase, Ovid, Medline and Cochrane Library. Egger's test was used to assess publication bias, and version 2 of the Cochrane risk of bias tool for randomized trials (roB2) was used to assess the risk of bias of the included studies. The methods applied for data synthesis were the Review Manager 5.4 software ((RevMan 5.4), the I2 statistical test, the Cochran Q test, the random effects model. Results: Twenty studies meeting all the eligibility criteria were selected and a total of 1,846 people were evaluated. On the one hand, eleven measured the malondialdehyde biomarker with 732 people evaluated and the result was statistically significant (SMD -2.65 [95% CI: -3.93, -1.37]); however, high heterogeneity was found (I2 = 97%). On the other hand, eleven measured superoxide dismutase (SOD) with 859 people evaluated and the result was statistically significant (SMD 1.24 [95% CI: 0.46, 2.01]), with heterogeneity (I2 = 95%). Discussion: The limitations of this study are the high heterogeneity; the moderate and high risk of bias in the studies analyzed; the lack of detailed information on the protocol applied in the yoga intervention, the methodology and the randomization process; and, finally, the lack of uniformity in the units of measurement of the biomarkers presented by each article. Conclusions: The findings obtained in this study suggest that the practice of yoga decreases the levels of oxidant substances such as malondialdehyde, ROS and increases the values of the antioxidant enzyme superoxide dismutase. However, more randomized clinical trials are required to confirm the beneficial effects of yoga practice. Others: This study did not have any type of financing.
