Using Wistar rats the effect of exercise was studied on the level of lipid peroxides, superoxide dismutase activity in the serum and certain tissues, and the contents of triglycerides (TG), total cholesterol (TChol), cholesterol in high density lipoprotein fractions (HDL -chol and HDL3-chol) and alpha-tocopherol in the serum. Low-grade exercise decreased by about 10% the lipid peroxide level in the serum, the soleus muscle and myocardium. Greater exercise increased the lipid peroxide level in the studied tissues. In the liver the lipid peroxide level rose by 20% independently of the degree of exercise. Superoxide activity increased proportionally to the grade of exercise in the myocardium, the soleus muscle and the liver. The serum alphatocopherol level increased in the groups of animals subjected to exercise. In the group with higher grade of exercise a slight fall of TChol in the serum and a fall of HDL and HDL3, cholesterol.

Na szczurach szczepu Wistar badano wpływ wysiłku fizycznego na zawartość nadtlenków lipidowych (NL), aktywność dysmutazy ponadtlenkowej (SOD) w surowicy krwi i wybranych tkankach, a także zawartość trójglicerydów (TG), cholesterolu całkowitego (TChol), cholesterolu lipoprotein o wysokiej gęstości (HDL-chol i HDL3-chol) oraz α-tokoferolu w surowicy. Stwierdzono, że mały wysiłek fizyczny wywołał około 10°/o zmniejszenie zawartości NL w surowicy, mięśniu płaszczkowatym i mięśniu sercowym. Zwiększony wysiłek fizyczny powodował wzrost NL w badanych tkankach. W wątrobie stwierdzono 20% wzrost NL niezależnie od stopnia wysiłku fizycznego. Aktywność SOD wzrastała proporcjonalnie do wysiłku fizycznego w mięśniu serca, mięśniu płaszczkowatym i wątrobie. Zawartość α-tokoferolu w surowicy wzrastała w grupach zwierząt trenujących. W grupie zwierząt o zwiększonym wysiłku fizycznym stwierdzono nieznaczny spadek TChol w surowicy oraz spadek cholesterolu w HDL i HDL2.
