The mean fibre areas of samples from m. semitendinosus, m. diaphragma and m. pectoralis transversus of thoroughbred horses and greyhounds have been compared with those in similar samples from other members of their species. Athletes (greyhounds and thoroughbreds) have larger fibres in the semitendinosus and diaphragm than their fellows. However, the mean area of pectoralis transversus is similar in the two types of animal within each species. During growth the mean fibre areas increase to a greater extent in athletes than in non-athletes. Detraining adult greyhounds for a period of one year did not signficantly alter the fibre area; nor were any sex differences detected. Although the mean fibre area of corresponding muscles is significantly larger in horses than in dogs, the difference is proportionately less than that of their live weights.
已将纯种马和灵缇犬的半腱肌、膈肌和胸横肌样本的平均纤维面积与同物种其他成员的类似样本进行了比较。运动员（灵缇犬和纯种马）的半腱肌和膈肌中的纤维比其同类更大。然而，每个物种内两种动物的胸横肌平均面积相似。在生长过程中，运动员的平均纤维面积比非运动员增加的幅度更大。成年灵缇犬停训一年并没有显著改变纤维面积；也未检测到任何性别差异。尽管马的相应肌肉的平均纤维面积明显大于狗，但差异与其体重的比例相比要小。
