Abstract

An animal model was used to determine the effect of dietary creatine supplementation on compensatory muscular hypertrophy and electrically stimulated performance of those muscles. Thirty-six rats were divided evenly into six groups. Two groups were surgical controls, two groups had the tibialis anterior ablated, to hypertrophy the extensor digitorum longus (EDL), and two groups the gastrocnemius and the plantaris ablated, to hypertrophy the soleus. One of each of these groups had their diet supplemented with creatine monohydrate. The size of the EDL and soleus were measured following surgical removal of the synergistic muscle and a 5-week supplementation period. Peak force, total tension over two 30 second intervals and time to one-half peak force were measured from the electrically stimulated muscle. Results indicated no difference in muscle size, peak force or tension due to the supplement. Time to one-half fatigue was increased in hypertrophied, non-supplemented soleus muscle.
