Study selection used ASReview with the SAFE rule; full-text screening was done in Covidence; risk of bias followed Cochrane guidance; certainty of evidence was appraised with GRADE.ResultsForty-one studies met inclusion. Pooled effects were statistically significant across domains: mental health µ(SMD)=0.76 (95% CrI 0.44–1.09), athletic performance µ(SMD)=0.88 (0.69–1.05), and cognitive performance µ(SMD)=0.81 (0.48–1.14).ConclusionBiofeedback and neurofeedback benefit athletes across mental, athletic, and cognitive outcomes. Given heterogeneity and sample sizes, further rigorous trials are warranted to refine the estimates.Systematic review registrationPROSPERO registration CRD420251015094.
