Physical exercise can produce oxidative stress, this situation could contribute cardiovascular risk in children and adolescents. The following study tries to evaluate the oxidative stress produced according to the handgrip strength in infancy. 70 healthy male subjects, ages 10 to 14 years, were studied. In the saliva samples, lipoperoxides (LPO), reduced glutathione (GSH), glutathione/lipoperoxides ratio and catalase were analyzed as biomarkers of oxidative stress. Children were divided into two groups according to their handgrip strength (high or low) measured by handgrip strength (TKK 5110). The groups were also divided into prepubertal and pubertal subjects. We found GSH's significantly low levels and of GSH/LPO in pubertal group with high handgrip strength. We could possibly conclude that the higher levels of handgrip strength could be associated with more oxidative stress in pubertal group with high fitness.
