The research has been conducted on 26 high qualification sportsmen of different sex, adapted to perform protracted physical activity of high intensity. Determined is the presence of gender differences in oxidizing and no oxidizing metabolism of L-arginine, including also the system of nitrogen oxide synthesis (oxidizing de novo and no oxidizing reutilization ways of NO synthesis), on different stages of their contention activity. On the stage of maximal functional possibilities and adaptation (beginning of contention period) for girls no oxidizing metabolism of arginine predominated with participation of arginase above oxidizing degradation of L-arginine with participation of NO-synthase. During the decline of functional possibilities (desadaptations in the middle and at the end of the competitions) the necessary level of nitrogen oxide synthesis is provided for girls mainly due to nitrogen oxide resynthesis from its stable metabolites, while for youths – due to the increase of oxidizing de novo nitrogen oxide synthesis ( as constitutive, also inducible).
