Abstract
The objective of this study was to perform a systematic review and meta-analysis of the articles that addressed the effect BA or carnosine supplementation on Physical exercise (PE)-induced oxidative stress (OS). We searched throughout PubMed, CAPES Periodic and SPORTDiscus human model peer review, randomized control studies with chronic BA or carnosine supplementation on PE-induced OS. We search papers published before May 2018. A total of 128 citations were found. Only four articles met criteria for inclusion. All four studies used healthy young (21y) sedentary, recreationally active or athletic participants. After a chorionic BA (~30 days) or carnosine (14 days) supplementation, the studies evaluated PE-induced OS both immediately and several hours after exercise (0.5 to 48 h). In response to PE-induced OS, when compared to placebo, BA/carnosine supplementation increased total antioxidant capacity [TAC; Effect Size (ES) = 0.35, 95% Confidence Interval (CI) 0.06 to 0.65, p = 0.02] and glutathione (GSH; ES = 0.75, 95% CI 0.32 to 1.19, p = 0.0007) concentrations while decreased pro-oxidant markers (ES = −1.19, 95% CI −1.48 to -0.80, p < 0.01) and superoxide dismutase (SOD) activity (ES = −0.58, 95% CI −1.10 to −0.06, p = 0.03). BA or carnosine supplementation did not prevent the increase in peroxidation markers (ES: −0.20, 95% CI −0.59 to 0.20, p = 0.33). In humans, following PE-induced OS, initial treatment trials of BA or carnosine supplementation seemed to increase TAC and GSH concentrations, while decreasing SOD activity. Also, albeit mitigating the acute increase in pro-oxidants, treatment did not decrease measured values of peroxidation markers.
