The percentages of three muscle fiber types in the biceps femoris and triceps brachii were determined in five breeds of horses: Belgians, Standardbreds, Thoroughbreds, Quarter Horses and Welsh ponies. Biopsies were taken from the two muscles from each of four 2-year-old untrained fillies of each breed. Percentages of red, white and intermediate fiber types were determined from tissues stained for succinic dehydrogenase activity. Intermediate fibers were the most numerous for all breeds. The difference between red and white fibers varied significantly with breed. Thoroughbreds had the highest percentage of red fibers and Belgians had the most white fibers.
测定了比利时马、标准赛马、纯种马、夸特马和威尔士矮种马五个品种马匹股二头肌和肱三头肌中三种肌纤维类型的百分比。从每个品种的4匹2岁未经训练的小母马中各取两匹的肌肉进行活检。根据琥珀酸脱氢酶活性染色的组织确定红色、白色和中间型纤维类型的百分比。所有品种中中间型纤维数量最多。红色和白色纤维的比例因品种而异。纯种马的红色纤维百分比最高，比利时马的白色纤维最多。
