Sixteen 8-week-old intact male miniature pigs were divided into three groups. Five pigs served as controls and were not subjected to forced exercise. Five pigs were exercised by endurance running on a treadmill and six pigs were exercised by sprint running on a treadmill. After 7 months of exercise all animals were exsanguinated and analyzed for body size and composition, heart size and composition, and changes of major muscle protein in the tibialis cranialis. Neither of the exercise programs significantly altered weight or composition of the body, heart or tibialis cranialis. It is likely that stage of growth, species size and sex, and type of exercise were important contributing factors to these results.
