Several investigations provided evidence that exercise may positively or negatively affect oxidative status on the basis of training load, training specificity, and the basal level of training. In particular, the degree of oxidative damage and the time course for elevation in oxidative stress markers, during and following both acute aerobic and anaerobic exercise, result to be dependent on the type, intensity, volume, and duration of muscle contraction, and also on gender, age, individual fitness levels, and nutritional status, leading to differences in the oxidative status between athletes in different sport disciplines [4, 8, 12, 13].
