The purpose was to determine the characteristics of female athletes’ perceptions of the psychological safety of the educational space and to compare the impact on the motivational orientation of female athletes of the game (Group I) and individual sports (Group II). An empirical study was conducted with female students from the Faculty of Physical Culture and Sports, with Group I (n = 26; 55.32%) participating in team sports (handball, volleyball), and Group II (n = 21; 44.68%) participating in individual sports (athletics). Psychodiagnostic research methods were used: the “Questionnaire of an Athlete’s Motivational Orientation” (I. Smoldovskaya) was used to study motivational orientation, and the “Psychological Safety of the Educational Space” questionnaire (I. Baeva, E. Volkova, E. Laktionova) was used to study female athletes’ perceptions of psychological safety in the educational space. Results. Differences between groups of female athletes with different perceptions of the level of psychological safety of the university’s educational space were established based on the components of female athletes’ motivational orientation (р<.05), indicating the influence of satisfaction with the parameters of interaction with students, teachers, and coaching staff. It has been proved that a high level of psychological safety (Group 1) was associated with athletes’ motivational focus on the results, on the business, proving the first hypothesis. A low level of psychological safety (Group 2) has been found to cause a focus on oneself, one’s prestige, interest, and benefit. A comparison was made between two groups of female athletes of game sports (Group I) and individual sports (Group II). Group I female athletes had a statistical advantage in the object-oriented and socially-oriented components, whereas Group II female athletes had a higher indicator of the personal-oriented component (р<.05). It was established that there were no statistically significant differences between groups in the result-oriented component of motivational orientation, demonstrating the lack of dependence of motivational orientation on the results of a specific type of sport and disproving the second hypothesis. Conclusions. It is recommended to implement the results obtained in the research into the female athletes’ psychological preparation.
ОСОБЛИВОСТІ ЗМІН ФЕРМЕНТІВ АМІНОТРАНСФЕРАЗ В КРОВІ ЖІНОК 18-21 РОКІВ В УМОВАХ ВИКОРИСТАННЯ РІЗНИХ ВИДІВ ФІТНЕСУ

Стаття присвячена дослідженню активності ферментів амінотрансфераз в крові дівчат 18-21 років в умовах використання різних видів фітнесу. Встановлено, що активність ферментів підвищується після навантаження в обох групах. В цілому підвищення активності АЛТ і АСТ в крові розцінюється як прояв патології, але ми вважаємо підвищення активності АЛТ і АСТ в крові може бути відображенням підвищення функції печінки і серця при фізичній активності. Активність АСТ достовірно вище після виконання навантаження в обох групах, що може вказувати на інтенсифікацію роботи циклу трикарбонових кислот. It was determined that the activity of the enzyme ALT in the blood of girls in the control group under the conditions of dance fitness at the beginning of the study increased after the load, the same tendency was observed after 3 months of training with all the mean values of the activity of the enzyme were within the normative values, but on During the third month of exercise after exercise, the ALT activity approached the upper limit of the norm. A decrease in the activity of ALT after 3 months of exercise prior to the load is established, which may indicate a lack of adaptive capacity of the body of the girls in the control group. In the main group, we observed an increase in the activity of this enzyme in the blood, both at the beginning of the study and after three months of training. Moreover, in contrast to the control group in the main, a sharp increase in the activity of the enzyme after 3 months of training is observed, than at the beginning of the study to the load. We observe the same dynamics in the activity of AST in the blood of girls. Particular attention should be paid to the activity of the enzyme in the control group after the load, both at the beginning and during the three months, where the activity of the corresponding enzyme in the blood was higher than the normative values, which indicates our view of inadequate loads and requires further investigation of this contingent, as for diseases of the cardiovascular system. In general, an increase in the activity of ALT and AST in the blood is considered a manifestation of the pathology, but we believe that an increase in the activity of ALT and AST in the blood can be a reflection of an increase in the function of the liver and heart during physical activity. ACT activity is reliably higher after loading in both groups, which may indicate an intensification of the tricarboxylic acid cycle. The activity of the enzyme GGT in the blood in the control group after the load increases both at the beginning and at the end of the study, although it is within the normal range. After three months of training, the activity of the corresponding enzyme is somewhat reduced from the initial values, especially it is noticeable to the load. The activation of gamma-glutamyltransferasa in these conditions may impair the glutathione redox cycle in renal tissues. In the main group, we observe a sharp decrease in the corresponding enzyme at the end of the study, both before and after the load. What says in our opinion about adaptation and the adequacy of these loads.
