StrongEvidence strength: strong. Randomised human trials or their synthesis, with the effect's size and interval recorded and no recorded weakness outstanding.Finding“The three-level random-effects model showed that oral ashwagandha supplementation was associated with improved overall exercise performance (Hedges’ g = 0.47, 95% CI [0.25, 0.69], p < 0.001; I2 = 60%; 95% prediction interval [−0.40, 1.33]; moderate certainty).”

How it is measured
Multi-level pooled standardised effect (Hedges g or standardised mean difference) computed across whatever exercise tests the primary trials used - aerobic, anaerobic and resistance - with each contributing test sign-aligned by the review authors so that a positive value favours the intervention. The constituent test types and the sign-alignment rule are recorded with each finding.
