OBJECTIVES: Topical menthol is increasingly used as a perceptual cooling strategy during exercise, yet its ergogenic potential and underlying mechanisms remain unclear. Unlike previous route-mixed meta-analyses, this systematic review and three-level meta-analysis specifically examined the effects of acute topical menthol application on exercise performance alongside perceptual and physiological responses.
DESIGN: Meta-analysis.
METHODS: Six databases were searched from inception to March 2026. Randomized or controlled trials examining acute topical menthol application during exercise were included. Risk of bias was assessed using RoB-2. Three-level meta-analyses accounted for dependence among multiple outcomes. Prespecified moderators included sex, training status, environmental condition, application method, application site, and exercise modality. Sensitivity analyses addressed outliers and influential cases.
RESULTS: Sixteen studies involving 191 participants were included. Topical menthol produced a small but significant improvement in exercise performance (g = 0.27, p = 0.02). Thermal sensation (g = -0.74) and perceived exertion (g = -0.35) were reduced, with a small improvement in thermal comfort (g = 0.34), whereas core body temperature was unchanged. Performance benefits were most evident in aerobic endurance tasks, following rub-on application methods, and under temperate conditions, whereas effects in hot environments (≥30 °C) were smaller and not statistically significant. Several subgroup findings were sensitive to influential observations and should be interpreted cautiously.
CONCLUSIONS: Acute topical menthol may provide a small ergogenic benefit primarily through perceptual cooling rather than physiological heat strain. Effects appear context dependent and most relevant for endurance exercise. Further well-controlled studies are needed to clarify optimal application strategies and environmental conditions.
