|---|
The effects of physical exercise on preference for various sapid solutions was studied in 58 healthy university students. After 30 mm of exercise using a bicycle ergometer at 50% VO2max (maximal oxygen uptake) intensity, a rating scale test on taste hedonic tone and the triangle test for taste absolute threshold were done. The test solutions were sucrose, NaCl, citric acid, caffeine and monosodium glutamate (MSG). Preference scale values for sucrose and citric acid increased after exercise, whereas the values for NaCl, caffeine and MSG were not changed. The absolute thresholds for all the sapid solutions did not differ for preand post-exercise. These findings indicate that in humans preference for sucrose and citric acid increase after physical exercise.
