The effect of Panax ginseng supplementation on markers of resistance exercise-induced muscle damage: a systematic review

INTRODUCTION: According to the PRISMA guidelines, this systematic review of randomized controlled trials examined whether Panax ginseng supplementation reduces resistance to exercise-induced muscle damage (EIMD). EVIDENCE ACQUISITION: Web of Science, SPORTDiscus and Medline databases were searched from the 16th th of December 2021 to the 18th th of February 2022. Inclusion criteria were studies in humans consuming Panax ginseng that employed resistance training as the damaging muscle protocol and measured markers implicated in the etiology of EIMD (muscle damage, muscle function and muscle soreness). The PEDro risk of bias assessment tool was used to appraise the studies critically. EVIDENCE SYNTHESIS: Conflicting evidence was evident in markers of muscle damage, muscle function and muscle soreness. The quality assessment suggested that all studies had some level of bias. CONCLUSIONS: From 180, six studies were included in the systematic review. The main findings suggest that Panax ginseng does not attenuate markers of EIMD following resistance training. However, research is still preliminary. Adequately powered sample sizes and well-controlled studies are warranted to clarify Panax ginseng's 's efficacy.
