to determine the effect of long-term thyrotoxicosis on muscle mitochondria , we measured representative mitochondrial enzymes from three different types of skeletal muscle ( fast-twitch red and fast-twitch white from the quadriceps , and slow-twitch red from the soleus ) in rats given 3 mg l-thyroxine and 1 mg triiodo-l-thyronine per kilogram of diet for 12 wk .
