Two experiments were conducted to determine whether high carbohydrate diets or exercise would have a greater influence on certain parameters of lipid metabolism. Male Fischer rats were used in both experiments, separated into exercise and sedentary groups, and fed either a high sucrose (63%) or a high starch (63%) diet. There were no differences in body weight or food consumption between the two diets. Exercise resulted in a highly significant increase in food consumption in both experiments. Rats fed sucrose had a higher serum cholesterol value than rats fed starch. Diet did not influence serum triglycerides but the rats on excercise had significantly lower serum triglycerides than the sedentary rats. Liver weight was significantly larger in rats fed sucrose. Sucrose caused an increase in the activity of both glucose-6-phosphate dehydrogenase and malic enzyme activities in liver tissue, whereas exercise caused an increase in the activity of these enzymes in adipose tissue.
进行了两项实验，以确定高碳水化合物饮食或运动对脂质代谢的某些参数是否有更大影响。两项实验均使用雄性费希尔大鼠，分为运动组和久坐组，并分别喂食高蔗糖（63%）或高淀粉（63%）饮食。两种饮食之间的体重或食物摄入量没有差异。在两项实验中，运动都导致食物摄入量显著增加。喂食蔗糖的大鼠血清胆固醇值高于喂食淀粉的大鼠。饮食对血清甘油三酯没有影响，但运动大鼠的血清甘油三酯明显低于久坐大鼠。喂食蔗糖的大鼠肝脏重量明显更大。蔗糖导致肝脏组织中葡萄糖-6-磷酸脱氢酶和苹果酸酶的活性增加，而运动导致脂肪组织中这些酶的活性增加。
