Menthol protects runners and cyclists against hot weather
It probably doesn't matter whether you use a homemade sports drink with menthol dissolved in it or gelatin capsules you suck on. The point is to keep menthol in your mouth while doing continuous intensive exercise. And whether you're a runner or cyclist, it'll help you to perform better, write Australian sports scientists, working at the University of Newcastle, in an article in the Scandinavian Journal of Medicine & Science in Sports.
Study
On one occasion the men were given a little Gatorade to drink every 15 minutes [Control]. On another occasion the researchers gave the subjects ice slurry at 1 degree Celsius. The idea behind this was that the slurry would reduce the subjects' body temperature and thus help enhance performance.
On the third occasion the men were given ordinary Gatorade, but every other kilometre they were given fluid in which menthol had been dissolved. They kept this in their mouth for 5 seconds before spitting it out. They spat it out for methodological reasons. Menthol may also be an interesting supplement for endurance athletes, and the researchers wanted to exclude this factor. They were only interested in the cooling effect of taste sensation of menthol.
Results
The menthol mouthwash on the other hand did have a statistically significant effect. When the men were given menthol they covered the five kilometres in 25.3 minutes.
Control = CON, circles; ice slurry = ICE, squares; menthol = MEN, triangles.
The ice slurry prevented the athletes' temperature from rising; the menthol did not do that. The ice slurry and the menthol had no effect on the men's heart rate.
