中文摘要：

为研究自愿转轮运动对长爪沙鼠（Meriones unguiculatus）体重的影响,在以前工作的基础上,分析了自愿转轮运动及8周后体重、胴体重和体水,以及心、肝、脾、肺、肾、性腺（睾丸或卵巢）、消化道、腓肠肌、比目鱼肌、肾周脂肪垫和肠系膜脂肪垫等器官及组织的重量变化。结果发现,自愿转轮运动条件下长爪沙鼠胴体湿重、体水和心、肝、脾、肾、腓肠肌、消化道等器官重量增加。自愿转轮运动对比目鱼肌和器官脂肪垫重量的影响存在性别差异。自愿转轮运动使雄性长爪沙鼠器官的脂肪垫重量增加,但雌性降低;对雄性长爪沙鼠比目鱼肌重量没有影响,但雌性增加。以上结果表明,自愿转轮运动促进了长爪沙鼠的体重增长,改变了长爪沙鼠的身体组成。内脏器官和体水重量的增加是体重增加的主要原因。

英文摘要：

In order to understand the effects of voluntary wheel exercise on body composition in male and female Mongolian Gerbils （ Meriortes unguiculatus ）, we determined the variations in body mass, body water content, carcass mass and the mass of liver, heart, lung, spleen, testis or ovary, digestive tracts, gastrocnemius, soleus, perirenal and mesenteric fat depots after 8-week voluntary wheel running exercise. Body mass, wet carcass mass, body water content, and the mass in heart, liver, spleen, kidneys, gastrocnemius, and gastrointestinal tract were significantly increased. There were significant sexual differences in the effects of voluntary wheel exercise on soleus and visceral fat depot mass. Visceral fat pad mass increased in males and, however, decreased in females. The mass of soleus kept relative stable in males and increased in females. Taken together, voluntary wheel running exercise stimulates the increase in body mass and the changes in body composition in both male and female gerbils. The increases in visceral organ mass and body water mass may be the main contributor to the changes in body mass.
