Abstract:
The effect of voluntary exercise training and influence of saline loading on blood pressure and cholesterol metabolism in rats were investigated in this study. Experimental animals used were male Wistar strain rats, aged 7 weeks old. These rats were allocated respectively into four groups, each of which consisted of 10 rats; sedentary control (SC), sedentary with 1 % saline loading (SS), training control (TC), and training with 1 % saline loading (TS) . In each of groups rats were sacrificed at the 10 th week.
Following results were obtained in this study.
1) The mean values of systolic blood pressure remained unchanged in all four groups, 2) serum and hepatic cholesterol levels were lowered by 10 weeks of exercise training, 3) the ratio of HDL-cholesterol to total cholesterol increased significantly in the training groups compared to that in the sedentary groups, 4) the incorporation of 14C-acetate into liver cholesterol was significantly lower in the SS group than in the SC group, and 5) a direct correlationship was found between the increased exercise level and the incorporation of acetate into liver cholesterol in both TC and TS groups.
