Abstract
The changes of locomotor activities in rat loaded with swimming exercise were recorded by our newly devised apparatus. In addition, changes of lipid peroxide levels and their related enzyme activities in rat brain, liver as well as blood were studied. The results obtained were as follows: 1. The locomotor activities in rat recorded by the apparatus showed the same patterns as that reported by the other researchers. 2. After the loading of swimming, locomotor activities in rat during the dark period decreased significantly as compared to those of the control. 3. The levels of TBARS (thiobarbituric acid reactive substance), SOD (superoxide dismutase) and GSH-px (glutathione peroxidase) in rat liver elevated after the swimming exercise in the first group, which was sacrificed after loading with one treatment (about 5 hours) exercise of swimming. 4. The level of TBARS in rat brain elevated after the swimming exercise in the second group, which was sacrificed after loading with two treatment exercise of swimming. 5. The level of TBARS in plasma decreased, and GSH-px, GR (glutathione reductase) and catalase in red blood cells elevated in the third group, which was sacrificed after two-hour rest following the loading with two treatment exercise of swimming. It is indicated that our newly devised apparatus is useful for monitoring locomotor activities in rat, and that the fatigue in rat caused by swimming load can be shown in terms of changes in the above activities. The elevation of the level of TBARS during the swimming exercise observed in tissues of the brain and liver may suggest that the lipid peroxidation will reflect a certain state of fatigue in rat.This publication has 0 references indexed in Scilit:
