“…Within this context, exercising generates positive adaptations that protect the body from damage caused by the free radicals, as demonstrated in our studies (44)(45) , which presented a greater eritrocytary activity of the GPx enzyme in trained triathletes compared with non-trained individuals, and an enhanced plasma total antioxidant ability (TRAP) after exercise on treadmill in both groups. However, the chronic training may interfere in the antioxidant system, generating hence, an imbalance between the free radicals production and the antioxidant response.…”

“…On the other hand, Subudhi et al (22) evaluated elite alpine ski racers after intense training and observed no change on the oxidative stress markers, suggesting that these athletes suffered a positive adaptation in their antioxidant mechanisms with training. Recently in our laboratory, Schneider (44) , Schneider et al (45) and Oliveira et al (46) , found a higher erythrocyte activity of the enzyme GPx in trained triathletes if compared to untrained individuals (figure 4) and an increased total plasmatic antioxidant capacity (TRAP) after treadmill exercise in both groups (figure 5). The higher GPx activity is in agreement with several studies that show the adaptation of the enzymatic defense system (32,41,(47)(48)(49) .…”

“…Este aumento da capacidade de defesa contra as ERO não se faz sentir apenas no músculo esquelético, estando presente em numerosos órgãos e tecidos. Por ex e mplo, em indivíduos treinados, comparativamente aos sedentários, está descrita uma maior capacidade antioxidante no plasma (22,94) e nos eritrócitos ( 1 0 6 ) . Em animais, tem sido demonstrado que o coração, o fígado e o pulmão evidenciam também melhorias na sua capacidade anti-oxidante após treino físico (8,10,17,117) .…”
