Abstract:
The effects of physical training and acute exercise (mechanical treadmill running) on the level of lipid peroxide in skeletal muscle of rats fed vitamin E-deficient or -supplemented diet were studied.
1. The level of lipid peroxide in skeletal muscle of untrained rats was significantly increased immediately after acute exercise (p<0.05), but physical training suppressed of increase in the level of lipid peroxide and an increase in the activity of superoxide dismutase. These findings were strongly shown in soleus muscle among the muscles examined in this experiment.
2. The level of lipid peroxide in soleus muscle was significantly increased in vitamin Edeficient rats compared to that of control rats (p<0.05) .
Conversely, the level of lipid peroxide in muscles was significantly depressed by feeding vitamin E -supplemented diet (p<0.05) .
3. Dietary vitamin E -supplementation did result in a increase in superoxide dismutase activity of muscle.
