Effect of exercise on transplanted extensor digitorum longus muscle in Sprague Dawley rats

Effect of exercise has been studied on intact and transplanted extensor digitorum longus (EDL) muscle in rats. Majority of muscle fibres hypertrophied and a few showed hyperplasia in intact and transplanted EDL muscle after exercise. The weight, dimensions and diameter of muscle fibres increased, while total muscle area, number of muscle fibres and the number and diameter of nuclei decreased after exercise in all the experimental groups. The DNA, RNA and protein contents were however increased after exercise.
