“Activity-Based Anorexia in Rats As a Function of Opportunity to Run on an Activity Wheel”, 1984 ():
This study concerns the effects of opportunity to run on activity-based anorexia in rats.
Animals were allowed different amounts of time to run on wheels while exposed to a restricted feeding schedule of one 90-min meal per day. Generally, the incidence of strong anorexia increased when opportunity exceeded 12 h of access to a free wheel.
Statistical analysis suggested that food intake declined with more opportunity and this decline was a function of the daily rate of change in wheel running. Body weight decline was due to the indirect effects of activity on food intake and the direct effects of rate of wheel running on energy expenditure.
