The numbers of fibres in the complete cross section of the semitendinosus were estimated in 58 equines and 59 canines of differing types. Animals selected for swiftness--thoroughbred horses and greyhounds--have a greater number of fibres in a cross section of their semitendinosus than other members of their species, whether as neonates or as adults. The numbers of fibres in the cross section increases during growth in both types of animal in each species.
在58匹不同类型的马和59只不同类型的犬中,对其半腱肌完整横截面上的纤维数量进行了估算。被选作速度型的动物——纯种马和灵缇犬——无论在幼年还是成年时,其半腱肌横截面上的纤维数量都比同物种的其他个体更多。在每个物种的这两种动物中,随着生长,横截面上的纤维数量都会增加。
