This study aimed to investigate the effects of L-menthol on endurance exercise capacity. The results showed that L-menthol administration can prolong running time and improve breathing comfort. Additionally, L-menthol can prevent the decrease in dyspnea threshold after running.
This study aimed to clarify the contribution of L-menthol administration to endurande exercise capacity. Thirteen male runners (age, 35.8 +/- 7.8 years; peak oxygen uptake, 62.7 +/- 6.8 mL kg(-1) min(-1)) ran on treadmills at fixed intensities of their anaerobic thresholds to exhaustion. All participants underwent three trials-water ingestion (W-IG), L-menthol mouth rinsing (M-MR), and L-menthol ingestion (M-IG)- in a random order every 5 min while running. Breathing comfort (BC) was measured immediately after fluid intake. Dyspnea threshold against external inspiratory resistance was examined before and after the running test. The running time with M-IG (1683.9 +/- 520.3 s) was longer than that with W-IG (1410.2 +/- 465.9 s, effect size [ES] = 0.55). BC with M-IG (2.00 +/- 0.74) was higher than that with W-IG (0.42 +/- 0.79) at exhaustion (ES > 2.00). The dyspnea threshold after running decreased to 19.2 +/- 7.6 cm H2O L-1 s(-1) with W-IG, whereas that with M-MR (26.2 +/- 6.5 cm H2O L-1 s(-1)) and M-IG (29.2 +/- 2.8 cm H2O L-1 s(-1)) remained high (p for interaction < 0.001). M-IG facilitated BC during running, improved endurance capacity, and prevented decreases in the dyspnea threshold against external inspiratory resistance after exhaustive running.
