Dynamics of indicators of motor capabilities of young female athletes in different phases of the ovarian-menstrual cycle

The results of the generalisation of the training experience of young female track and field athletes show that taking into account the biological features of the female body in sports practice consists, mainly, in the application of a smaller amount of training load. At the same time, cyclical changes in the level of manifestation of physical qualities, which are due to the phases of the ovarian-menstrual cycle, are not taken into account. Therefore, the purpose of the study was to study the dynamic indicators of the motor capabilities of young multi-athletes during the ovarian-menstrual cycle. To realise the established goal, the following research methods were used: analysis, systematisation and generalisation of the data of literary sources on the studied issues; pedagogical (declarative experiment, testing); sociological (questionnaires); methods of mathematical statistics. 23 female track and field athletes aged 17-18 took part in the study. The level of motor capabilities of the subjects was determined on the days that correspond to a certain phase of the menstrual cycle. The dynamics of indicators of physical work capacity, strength, speed-strength abilities, as well as speed and speed endurance were determined. It was found out that the level of manifestation of the mentioned indicators in female athletes during the ovarian-menstrual cycle is not constant and changes in accordance with the phases of the cycle and has a heterochronic character. The lowest level of physical efficiency, strength, speed and strength abilities, speed and speed endurance was observed in the premenstrual and menstrual phase of the ovarian-menstrual cycle, which determines the necessity of reducing the volume of training load in the last (fourth) week of the cycle. The highest level in the cycle of manifestation of motor abilities of girls-athletes is characteristic of the postmenstrual and postovulatory phase, which allows for the planning the maximum physical activity in this period
