The level of anaerobic threshold determined from the gas exchange and acid-base equilibrium of the blood in women and men.

The investigations were carried out on 6 female and 6 male students of the Physical Education Academy for determining the levels of anaerobic threshold on the ground of an analysis of the curves of respiratory parameters during exercise of increasing intensity, and in another set of experiments--on the ground of disturbances of acid-base equilibrium of the blood during submaximal exercise of nearly threshold intensity. Additionally it was tried to demonstrate possible differences in the AT level between females and males. The investigations showed that in the tests with acid-base equilibrium analysis the anaerobic threshold appeared in females at the level of 52% of VO2 max and in males at the level of 61%. In the tests with gas exchange analysis these levels were 58% in females and 67% in males. The differences in these results obtained by both methods of analysis were not significant statistically.
