Menthol mouth rinsing does not improve running performance at different temperature ranges

The dataset from this study pertains to the impact of L-menthol (MEN) mouth rinsing (MR) on running performance and psychophysiological responses during a 10-km time trial in different temperature conditions. The study was conducted with eight male participants (mean age = 34 ± 4 years; VO2max = 64.5 ± 5.5 ml/kg/min) in a randomized, double-blind, placebo-controlled, crossover design.

Participants completed a total of seven 10-km running time trials (three at 22°C, two at 28°C, and two at 34°C) under three experimental conditions: control (CON; only at 22°C), placebo (PLA), and L-menthol (MEN). The data include 10-km performance times for each condition and temperature, as well as psychophysiological measures such as thermal sensation, comfort, perceived effort, and affective response.

Results indicated that there were no significant differences in performance times between MEN and PLA across all temperature conditions (P > 0.05), although MEN showed a non-significant trend towards faster times at 28°C (54 seconds faster) and at 34°C (36 seconds faster). Psychophysiological measures varied during the trials but were not significantly influenced by MEN mouth rinsing.

本研究中的数据集关乎L-薄荷醇（MEN）漱口水（MR）对不同温度条件下10公里计时赛跑表现及生理心理反应的影响。该研究采用随机、双盲、安慰剂对照、交叉设计的实验方法，对八名男性参与者（平均年龄34±4岁；最大摄氧量VO2max为64.5±5.5 ml/kg/min）进行了实验。参与者共完成了七次10公里的跑步时间测试（其中三次在22°C下，两次在28°C下，两次在34°C下），分为三种实验条件：对照组（CON；仅在22°C下进行）、安慰剂组（PLA）和L-薄荷醇组（MEN）。数据包括每种条件及温度下的10公里成绩时间，以及生理心理指标，如热感、舒适度、感知努力程度和情感反应。研究结果指出，在所有温度条件下，MEN组和PLA组在成绩时间上无显著差异（P>0.05），尽管在28°C下（快54秒）和34°C下（快36秒）MEN组显示出时间更快的非显著趋势。生理心理指标在试验过程中有所变化，但MEN漱口水对生理心理指标的影响并不显著。
