The effect of exercise and induced expectations on visceral perception in asthmatic patients.

Studied 32 adult asthmatics in a 2 × 2-factorial design to examine the effect of physical exercise due to an ergometer capacity test and induced expectations about the consequences of this task on broncho-constriction. Two sets of instructions were used to induce anticipations of harmful and non-harmful consequences. Dependent variables were registered: airways resistance, skin resistance, and visceral perception (rating of physiological changes). Only small effects of the different ergometer loads on physiological responding and no effects of the experimental variables on visceral perception were found using analysis of variance (ANOVA), whereas analysis of covariance (ANCOVA) demonstrated that the induced harmful anticipation significantly intensified the perception of visceral changes and had some influence on asthma-relevant physiological responding.
