Popis: Introduction. The literature data prove the necessity to reorganize the physical education (PE) of female students. This can be expressed, on the one hand, in taking into consideration the menstrual cycle (MC) phases when distributing and orienting physical loads, and on the other hand, in searching for methodological approaches, aimed at improving the body functional state. Incorrect structure of the PE process can negatively affect the functional state of young female athletes and the preservation of their health. Purpose. To study the influence of specially formed dancing health-improving classes on the functional state of female students’ bodies (taking into account the phases of MC) and to evaluate their effectiveness. Methods. 26 female students of the sporting training department were under supervision: two groups of 13 persons – the main group and the control one. They were examined at the beginning and at the end of the academic year. Two exercises were performed. Each lasted for 3 minutes, with a three-minute break. The intensity of the first exercise was selected so that the heart rate did not exceed 120-125 beats per minute, and 140-145 beats per minute for the second one. Besides, pulse and arterial blood pressure were measured in the initial condition before the start of the test, as well as after its completion. On the base of these measurements, the systolic blood volume was calculated according to Starr’s formula. The maximum oxygen consumption (MOC) was calculated according to Karpman’s formula. The mental working capacity was determined by means of the "Landolt Ring" test. The mathematical processing of the obtained data was carried out. Results. The background indicators of heart rate in two groups both at the beginning and at the end of the academic year were within the limits of physiologically normal conditions, the differences in the heart rate indicators of the groups were unreliable. The similar measurements were done after the female students had performed the two stages of exercises. They showed that in the main group the cardiovascular system indicators at the end of the academic year were more favorable. Against the background of a higher PWC170 indicator, they had not so high indicators of systolic and minute volumes of blood, as the control group students had. This proved a more economical functioning of the circulatory system in the process of physical activity. If the MOC at the beginning of the academic year was almost identical and was about 2.3 l/min for both groups, at the end of the second semester, the students of the main group significantly increased MOC, while in the control group it only slightly increased. At the end of the academic year, we recorded a close relationship between the PWC170 and the speed of information processing (r = 0.97) in the postmenstrual period. At the same time, a high correlation with the percentage of correct decisions was kept. In the period of ovulation, the relationship of the PWC170 with the time of test solution and the analysis of one sign remained the same as in the first survey. During the post-ovulatory phase, the dependence between the PWC170 and the speed of information processing increased. During the premenstrual and menstrual phases the stable relationship between the indicators of mental and physical capacity was not found. Conclusion. It has been established that under the influence of annual dancing health-improving classes the female students improved the state of the cardiorespiratory system, increasing the efficiency of its functioning in the course of physical work, which ensured an improved physical efficiency, an increase of work capacity and, most importantly, a significant increase of the maximum oxygen consumption.
