Abstract:
Forty-eight male Wistar strain rats have been used to study the effect of voluntary exercise training on the succinate dehydrogenase (SDH) activity, blood lipids, and adrenal catecholamines. The animals were trained for 10 weeks with a voluntary running in revolving wheels. SDH activities in heart and skeletal muscles, total cholesterol and triglyceride in serum and adrenal catecholamines were determined right after rats reached a peak distance of voluntary running and at the end of training. Training produced no significant increase in the SDH activities of cardiac and skeletal muscles at 13 and 17 weeks of age. Physical training reduced 12%of serum cholesterol concentration (p<0.05) . The serum triglyceride concentration of trained group remained lower than that of the sedentary throughout a period of training (p<0.05) . The voluntary exercised rats had higher adrenal catecholamine concentration as compared with the sedentary at 13 weeks old (p<0.05), but there was no significant difference at 17 weeks old. These data demonstrated that voluntary training did not increase endurance capacity, and adrenal catecholamines, but lowered serum lipid levels.
