Abstract Summary
Objective: To evaluate the effects of Ashwagandha (Withania somnifera) supplementation on physical performance, including muscle strength, cardiorespiratory fitness, and fatigue/recovery, in healthy individuals.
Context: Ashwagandha is traditionally recognized for its adaptogenic properties, potentially enhancing physical performance and vitality. This study systematically reviews and analyzes clinical trials to assess its efficacy in improving physical performance metrics.
Methods Used
Approach: A systematic review and Bayesian meta-analysis were conducted, adhering to PRISMA guidelines, to evaluate the impact of Ashwagandha supplementation on physical performance.
Data Collection: Databases including PubMed, ScienceDirect, and Google Scholar were searched for clinical trials up to 2020. Thirteen studies met the inclusion criteria, with twelve included in the quantitative analysis. The analysis focused on variables such as muscle strength, VO₂ max, muscle fatigue, tiredness, and physical recovery.
Researchers' Summary of Findings
The meta-analysis revealed that Ashwagandha supplementation was more effective than placebo in enhancing physical performance variables in healthy men and women. The Bayesian models indicated that future interventions might yield beneficial outcomes in the analyzed parameters, considering the 95% credible intervals for the meta-analytic effect size. The study suggests that Ashwagandha supplementation could be a viable strategy to improve physical performance, though further research is recommended to confirm these findings.
