在本研究中，研究了人类是否会对一种味道产生厌恶，如果是这样，这种效果需要经历胃肠道不适。为此，总共58名参与者在30分钟跑步锻炼之前直接食用或仅品尝特定风味的溶液。在这两种情况下，这导致与未明确与运动配对的另一种味道的评价相比，对味道（味道和气味）的主观喜欢的负向变化，指示条件性味道厌恶。主观经历的运动相关的胃肠道不适的程度并没有预测这种负面的享乐转移的味道配对与运行的运动，这意味着这种痛苦可能不是一个先决条件运动诱导的味道厌恶学习人类。(C)2009爱思唯尔有限公司保留所有权利。
In the present study, it was investigated whether humans acquire an aversion for a flavor paired with a single bout of exercise, and if so, to what degree this effect requires the experience of gastrointestinal distress. To this end, a total of 58 participants either consumed or merely tasted a specifically flavored solution directly prior to a 30 min running exercise. In both cases this led to a negative shift in subjective liking of the flavor (taste and odor) in comparison to the evaluation of another flavor not explicitly paired with exercise, indicative of a conditioned flavor aversion. The degree of subjectively experienced exercise-related gastrointestinal distress did not predict this negative hedonic shift for the flavor paired with the running exercise, implying that such distress may not be a prerequisite for exercise-induced flavor aversion learning in humans.
