Rapid Weight Loss of Up to Five Percent of the Body Mass in Less Than 7 Days Does Not Affect Physical Performance in Official Olympic Combat Athletes With Weight Classes: A Systematic Review With Meta-Analysis
Given the relevance of the effects that weight loss can generate on the physical performance in athletes, this study performed a systematic review with meta-analysis of the published literature on rapid weight loss (RWL) and examined its impact on the physical performance in Official Olympic combat sports athletes. The âPreferred Reporting Items for Systematic Reviews and Meta-Analysisâ (PRISMA) guidelines were followed to ensure an ethical and complete reporting of the findings. PubMed, SPORT Discus, and EBSCO were the electronic databases explored for article retrieval and selection. The following string was applied: âRWLâ OR âweight lossâ OR âweight reductionâ AND âjudoâ OR âwrestlingâ or âtaekwondoâ or âboxingâ AND âperformance.â Based on the quality analysis, conducted according to the âTool for the assessment of study quality and reporting in exercise training studiesâ (TESTEX), ten articles achieved a score >6 points. The meta-analysis showed a significant difference in pre- vs. postweight loss (p = 0.003) and no effects in pre- vs. post-power and strength performance analysis (p > 0.05 for both results). Based on our systematic review and metaanalysis of the literature, RWL up to â€5% of the body mass in less than 7 days does not influence performance outcomes in Official Olympic combat athletes with weight classes, considering the strength and power measures
