ABSTRACT
Voluntary running establishes aversion to the paired taste in rats. A proposed mechanism underlying this taste aversion learning is energy expenditure caused by the running. The energy expenditure hypothesis predicts that running-based taste aversion should be alleviated by a calorie supply since this would compensate for the energy expended by running. Accordingly, running-based taste aversion would be less readily established to a caloric substance (20% sucrose solution) than to a noncaloric substance (0.2% sodium saccharin solution). Because the sucrose and saccharin aversions were equivalent in Experiment 1, the validity of the energy expenditure hypothesis was questioned. Experiments 2 and 3 also pose a problem for this hypothesis, as post-session calorie supply by glucose tablets failed to alleviate running-based aversion to salty water.
