title: Prediction of obligatory exercise by exercise-related imagery.
abstract: Obligatory exercise is a compulsive behavior pattern in which exercise dominates daily life at the expense of other activities and lack of exercise produces withdrawal symptoms. This study examined the hypothesis that obligatory exercise is motivated similarly to eating disorders (cf. S. P. Coen & B. M. Ogles, 1993) and would be predicted by appearance-related imagery. Obligatory exercise (J. K. Thompson & L. Pasman, 1991) and exercise imagery (H. A. Hausenblas, C. R. Hall, W. M. Rodgers, & K. J. Munroe, 1999) were assessed before and after a 10-week exercise program in 243 adult exercisers. Regression analyses revealed that imagery accounted for 20% of the variance in obligatory exercise. Appearance-related imagery did not predict significantly obligatory exercise. Energy-related imagery was the strongest predictor. Obligatory exercise may not be as associated with appearance-related concerns as eating disorders, suggesting different motivational bases for these 2 behavioral patterns.
