Myoglobin content (Mb) and enzyme activity in murine skeletal and cardiac muscles were determined. Mb in the red part of m. vastus lateralis and m. gastrocnemius was about 30 times that in the white part. Hexokinase (HK) and citrate synthase (CS) activity in the red parts was about 2.8 and 3.5 times respectively as great as those in the white parts. Mb and the enzyme activity of m. soleus were similar to those in the red parts of the two muscles. Cardiac muscle had the highest Mb and enzyme activity. There was significant correlation between Mb and HK activity (r=0.912, n=60) and between Mb and CS activity (r=0.856, n=60). The results indicate that the red part, with higher Mb, has higher oxidative capacity than the white part in the same muscle.
