项目摘要

Recently, effects of lack of exercise and westernizing of food habits on health status based urbanizing of daily life are focused in Japan. On the other hand, health status of students belonged to an athletic club under unbalanced nutritional in take are also picked up. A free moving system was designed for exercise of rats, that is 4 case (80 m * 20 cm * 25 cm) were arranged lengthways through three pipes (10 cm ID), and drinking water on upstairs and diets were set up under ground. In the free moving system (Ex+) or the conventional system (Ex-), rats fed low magnesium (Mg1/3) diet or normal diet (Mg+), (total 4 groups ; 1)Ex-Mg+, 2)Ex+Mg+, 3)Ex-Mg-, 4)Ex+Mg-) were kept for 40 days. Muscle weight decreased in rats of group 4 compared to group 1.After sampling, biochemical items in plasma, and total lipid, lipid peroxide, protein and superoxide dismutase (total-SOD,Mn-SOD) in liver were measured. In plasma of group 4, ALB,AMY,LDH,CPK,UA & CRE were significantly low compared to that of group 1 and PL,T-CHO,ALB,ALP & UA in group 4 were low compared to that of group2.In plasma of group 3, UA was significantly low compared to that of group 1 and PL,ALB,ALP,CHE & UA were low compared to group 2.In lipid peroxide of liver of groups 1 & 2 was significantly high compared to that of other groups. These results suggested that health status under low Mg nutrition would be fallen down by exercise.

最近，缺乏运动和饮食习惯西化对基于日常生活城市化的健康状况的影响在日本受到关注。另一方面，体育俱乐部学生营养摄入不均衡的健康状况也有所改善。设计大鼠自由活动系统，即通过3根管道（内径10cm）纵向排列4个箱子（80m*20cm*25cm），楼上饮水，地下设置饮食。在自由移动系统（Ex+）或常规系统（Ex-）中，大鼠饲喂低镁（Mg1/3）饮食或正常饮食（Mg+），（共4组；1）Ex-Mg+，2）Ex+Mg+ ，3)Ex-Mg-，4)Ex+Mg-)保存40天。第4组大鼠肌肉质量较第1组有所下降。取样后测定血浆生化指标、肝脏总脂质、过氧化脂质、蛋白质和超氧化物歧化酶（总SOD、Mn-SOD）。第4组血浆中ALB、AMY、LDH、CPK、UA、CRE较第1组显着降低，第4组PL、T-CHO、ALB、ALP、UA较第2组显着降低。第3组血浆中UA较第1组显着降低，PL、ALB、ALP、CHE、UA较第2组显着降低。第1、2组肝脏脂质过氧化物显着降低。与其他群体相比较高。这些结果表明，低镁营养下的健康状况会因运动而下降。
