测定了5种马（比利时马、标准马、纯种马、四分之一马和威尔士马）股二头肌和肱三头肌中3种肌纤维的百分比。对每个品种的4匹未经训练的2岁小母马的2块肌肉进行了活组织检查。用琥珀酸脱氢酶活性染色测定组织中红色、白色和中间纤维类型的百分比。中间纤维在所有品种中数量最多。红色和白色纤维的差异因品种而异。纯种马的红色纤维比例最高，比利时人的白色纤维比例最高。
The percentages of 3 muscle fiber types in the biceps femoris and triceps brachii were determined in 5 breeds of horses: Belgians, Standardbreds, Thoroughbreds, Quarter Hourses and Welsh ponies. Biopsies were taken from the 2 muscles from each of 4 2-yr-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.
