Effect of physical exercise on human preference for solutions of various sweet substances.

The effect of physical exercise on taste preference for various sweet solutions was examined with 44 healthy university students (19 men, 25 women; M age=20, SD=0.9). None had participated in regular exercise programs during the previous year.

EMG activities of facial and chewing muscles of human adults in response to taste stimuli.

To evaluate facial expression patterns induced by different taste stimuli, electromyograms (EMG) of the facial and chewing muscles of 12 healthy university students, aged 20 to 23 years, were analyzed. Sucrose (sweet), NaCl (salty), citric acid (sour), quinine-HCl (bitter), monosodium glutamate (MSG; umami), homogentisic acid (harsh), tannic acid (astringent), and capsaicine (pungent) were the taste stimuli used. Rating scale tests were made to assess the hedonics (pleasantness) of the taste stimuli.
