Summary: To determine the effects of exercise in experimental autoimmune myocarditis, Guinea pigs immunised with heterologous heart protein (rat heart), Freund's complete adjuvant, and pertussis vaccine (treated group) were exercised on a treadmill for a total of 11 weeks and compared with non-exercise treated animals. In vivo heart rates and pressures, in vitro left ventricular pressure-volume relations, myocardial histology, circulating antiheart antibody, and in vitro lymphocyte stimulation were determined. Exercise resulted in increased cardiac dilatation in treated animals as assessed by in vitro left ventricular pressure-volume relations compared with non-exercise treated animals (at 8 mmHg 1.41(0.17) ml·kg-1 vs 1.20(0.17) ml·kg-1 respectively, p
