Menthol has been regularly utilized as a treatment in sports related injuries for many years, yet little is known about its physiological interactions or its effect on performance. Our previous study indicates that topically applied menthol may cause an acute decrease in blood flow and may improve strength capabilities. The purpose of this study is to examine the effects of two different concentrations of menthol (3.5% and 10%) on systemic blood flow and strength. 16 subjects participated in this 4 week study examining blood flow and strength effects after menthol or control treatment. Results indicate that the 3.5% menthol causes a significant (< .05) decrease in blood flow, and arterial diameter in the treated leg, and decreased blood flow in the untreated leg. 10% menthol treatment attenuates the statistically significant increase in blood flow observed with Control treatment, and significantly decreases arterial diameter in the treated leg. Results indicate that menthol is capable of suppressing arterial blood flow locally and systemically.
