Abstract: RESUMOO presente estudo investigou o efeito de quatro e oito semanas de treinamento físico sobre a atividade dos complexos da cadeia transportadora de elétrons (CTE) e os marcadores de estresse oxidativo em fígado de camundongos. Vinte e um camundongos (CF1, 30-35g) foram distribuídos nos seguintes grupos: não treinado (NT); treinado quatro semanas (T4); treinado oito semanas (T8). Quarenta e oito horas após a última sessão de treinamento os animais foram mortos por decapitação e o fígado foi retirado e estoca… Show more

“…Some studies have argued that physical training has no effect on antioxidant enzymes in the liver and in the heart 29 . However, the results of our study, in agreement with other findings, showed that physical training increases SOD activity in the liver 5,6 and in the heart 15 . After physical training, SOD activity increases, probably in response to oxidative stress induced by exercise.…”

“…In addition, OS affects the physiological functioning of several organs, such as the liver and the heart. The high metabolic rate of these organs is associated with the high flow of electrons in the mitochondrial respiratory chain and the consequent high production of ROS 5 . The liver is the main organ in metabolic control, and several authors suggest that it is substantially affected by OS during and after physical exercise 6,7 .…”

“…Moreover, the effect of training on the activity and expression of CAT is inconsistent and controversial [ 47 ]. However, increased activity of this enzyme has been observed in rat liver [ 48 ], mice liver [ 49 ] and trained rat heart [ 50 ].…”
