白肌纤维

20mg／kg剂量时红、白肌纤维密度均达极显著水平（P＜0.01）。

And the both densities of RMF and white muscle fiber ( WMF ) in the treatment of 20 mg / kg increased very significantly ( P < 0 01 ) .

分别用红、白肌纤维为肌桥，桥接狗股神经和正中神经缺损3cm。

Muscular bridges of red or white muscle fibers were used to suture respectively dogs ' femoral nerve and median nerve 3 cm defects .

20mg／kg剂量红、白肌纤维横径均极显著增粗（P＜0.01），最终导致背最长肌面积扩大7.59%～39.15%。

The diameters of RMF and WMF both increased very significantly ( P < 0 01 ) in the treatment of 20 mg / kg . This caused the area of longissimus to increase by 7 59 % - 39 15 % .

红、白肌纤维为肌桥缝接狗神经缺损的实验形态学研究

Experimental Morphological Research on Muscular Bridge of Red or White Muscle Fibers Suturing Defective Nerves in Dogs

结果表明，腿肌肌纤维类型有3种，即红肌纤维，白肌纤维和中间型肌纤维，而胸肌肌纤维类型有2种，即白肌纤维和中间型肌纤维。

The results showed that the muscle fibers were divided into three types : red muscle fibers , white fibers and the middle fibers .

白肌肌纤维的数量和排列方式受ATR影响显著，肌节长度缩短。

Number and arrangement of myofibers ( esp. white muscle myofibers ) were significantly influenced , and trunk myotomes shortened .

腓肠肌是Ⅱ型，即白快缩肌纤维，在有氧能力、收缩速度、以及疲劳阻力方面较差，属于高强度、短时间运动的肌肉类型。

Gastrocnemius is type II , that is shrinking fast white muscle fibers , in the aspects of aerobic capacity , contraction speed and fatigue resistance is poor , Belonging to high-intensity , short-term movement of the muscle type .
