November 18/Shizuoka, Japan/Technology Business Journal -- According to recent research from Shizuoka, Japan, "In order to determine the influence of prolonged exercise on sensitivity to sweet taste, we investigated the relationship between physical fatigue and palatability and/or taste intensity by performing sensory evaluation tests. The subjects hiked up a 36-km mountain trail for 12 hours, and we used 100- and 300-mM sucrose solutions as test samples."
"The taste intensity and palatability of the sucrose solutions did not change significantly during exercise. However, a slight change in palatability was observed," wrote M. Narukawa and colleagues, University of Shizuoka.
