The effect of various phases of the menstrual cycle on the tolerance of a statoergonometric test

Abstract

Relevance. Nowadays, there is a worldwide practice of training women for piloting combat aircraft. An important problem arises of studying the tolerability of aerobatic overload by the female body, including during various periods of the ovarian-menstrual cycle.

The main aim of the study is to assess the tolerance of prolonged static tension of the muscles of the lower extremities and the abdominal press, as an equivalent to the tolerance of overload, by women in various phases of ovarian-menstrual cycle.

Methods. The static tension of the muscles of the legs and abdominal muscles is modeled using a five-step statergometric test. Tolerance is evaluated by the dynamics of indicators of computer stabilization before and after the test. The study involves 15 healthy women aged 21-23 years. Registration of estimated indicators is carried out in different phases of the ovarian-menstrual cycle.

Results. It is established that the postmenstrual phase of ovarian-menstrual cycle is characterized by good tolerance to long-term static tension of the muscles of the legs and abdominal muscles. Load tolerance decreases in the premenstrual phase.

Conclusion. The obtained data suggest that the tolerance of aerobatic overload in women may decrease in the premenstrual phase compared with the postmenstrual phase.
