摘要: 通过计算机断层扫描(computed tomography,CT)技术对饲喂酪蛋白磷酸肽(casein phosphopeptide,CPP)副产物——酪蛋白非磷酸肽(casein non-phosphopeptide,CNPP)的大鼠的躯干及下肢根部肌群、腰椎周围肌群、背部肌群、肩胛内侧肌群、上肢左侧根部肌群的横截面积进行检测。结果发现:到第50天时,自由活动组中饲喂中剂量酪蛋白非磷酸肽的大鼠的躯干及下肢根部肌群、背部肌群、肩胛内侧肌群和上肢左侧根部肌群的横截面积增长量较高,分别是空白组的1.19、1.16、1.24、1.93 倍;抗阻力运动组中喂高剂量酪蛋白非磷酸肽的大鼠躯干及下肢根部肌群、背部肌群的横截面积增长量显著大于自由活动组(P<0.05),同时也显著大于相同剂量的乳清蛋白组(P<0.05)。表明酪蛋白非磷酸肽协同抗阻力运动可以促进大鼠肌肉质量的增加。

Abstract: The cross-sectional areas of trunk and lower limb muscle groups, psoas major muscle groups, back muscle groups, beta scapular muscle groups, and left upper limb muscle groups in rats administered with casein non-phosphopeptide (CNPP), a byproduct of the production of casein phosphopeptide (CPP) were determined using a transverse spiral computed tomography (CT) scanner. The results showed that the cross-sectional areas of trunk and lower limb muscle groups, back muscle groups, beta scapular muscle groups, and left upper limb muscle groups from no exercise (NE) rats administered with moderate-dose CNPP were significantly 1.19, 1.16, 1.24 and 1.93 times greater than those of the blank group on day 50, respectively (P < 0.05). The increases in the cross-sectional areas of trunk and lower limb muscle groups, back muscle groups of resistance exercise (RE) rats after administration of high-dose CNPP were significantly higher than those of NE rats (P < 0.05), and also significantly higher than those of RE rats administered with lactalbumin at the same dose (P < 0.05). These findings have demonstrated that a combination of physical exercise and dietary supplementation with CNPP can synergistically improve muscle mass in rats.
