Sarcomere number and sarcomere length were studied in six groups of kittens ranging in age from 10 minutes to 5 months and compared with those of adult cats. Although the soleus muscle is a slow contracting muscle and the tibialis anterior a fast contracting muscle, both have previously been shown to have the same range relative to ankle movement. For a given angle of articulation the sarcomere length was found to be the same at all ages except perhaps for the newly born. In contrast, the sarcomere number differed considerably, being much higher in the older animals. The relationship between active tension and muscle length was also measured, and again no difference was found between the muscles at any age, although the shape of the curves for the soleus and tibialis anterior was different.
研究了六组年龄从10分钟到5个月不等的小猫的肌节数量和肌节长度，并与成年猫的进行了比较。虽然比目鱼肌是慢收缩肌，而胫骨前肌是快收缩肌，但之前已表明两者相对于踝关节运动具有相同的范围。对于给定的关节角度，发现除了新生小猫外，所有年龄段的肌节长度都相同。相比之下，肌节数量差异很大，年龄较大的动物中肌节数量要高得多。还测量了主动张力与肌肉长度之间的关系，同样，在任何年龄的肌肉之间都未发现差异，尽管比目鱼肌和胫骨前肌的曲线形状不同。
