Abstract: 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 h, 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. In particular, the palatability of the 300-mM solution increased with an increase in the degree of physical fatigue towards the end of the exercise.
