Background and Study Aim. The level of functional preparedness of the population is influenced by many factors. The greatest influence is exerted by the economic condition of the country, climatic features of the region, food quality, environmental factor, social status of the population. Therefore, functional readiness standards should be updated periodically. For an objective assessment of functional readiness, all energy potential should be considered: aerobic, anaerobic lactatic and alactatic. Women of different somatotypes have significant differences in the degree of development of indicators of functional preparedness. Hypothesis. The models of functional preparedness developed by us for women of different somatotypes will clearly demonstrate significant differences in the level of preparedness in representatives of different somatotypes. The aim of the study is to develop standards of functional readiness for women aged 25-35 and models of functional preparedness for women of different somatotypes. Material and methods. The study involved women aged 25-35 years (n = 392). Somatotype was determined in all subjects. The power of aerobic energy supply processes was determined by the method of bicycle ergometry according to the PWC 170 test. The threshold of anaerobic metabolism was determined by the test with a stepwise increasing load. The capacity of anaerobic lactatic energy supply processes of muscular activity was determined by a bicycle ergometric 60-second test. The power of anaerobic lactatic and alactatic energy supply processes was determined by Wingate anaerobic tests WAnT 30 and WAnT 10. Standards of functional preparedness were developed according to the author's method based on the rule 3σ. Results. Functional preparedness standards have been developed for women aged 25-35 according to the full range of muscular energy supply regimes. Models of functional preparedness for women 25-35 years of different somatotypes have been developed. Conclusions. The developed standards are based on modern experimental data and consider all human energy potential (aerobic, anaerobic lactatic and anaerobic alactatic). Standards of functional preparedness cannot be universal for different countries and even different regions of large countries. Models of functional preparedness of women of different somatotypes show a significant difference from the standards set for women without somatotype. Somatotype should be considered when assessing indicators of functional preparedness.

Background and Study Aim. The variability of interpopulation morphofunctional traits in humans is closely related to various environmental factors. However, body composition has a significant relationship with indicators of physical fitness, human performance, with its adaptation to environmental conditions. The aim of the work is to investigate ethno-territorial variability of morphological characteristics of students studying at Ukrainian universities. Material and methods. Datum were from cross-sectional surveys since 2014 through 2019. Male students aged 18–25 years old (n = 488) of Ivano-Frankivsk National Medical University from different countries were recruited. Anthropometric methods included body length (BH), body weight (BW), chest girth in three states: at maximum, maximum inspiration and rest; skinfolds thicknesses and epiphysis measurements. Somatometric physical development indicators (body mass index - BMI), Kettle’, Pignet’, Livi’ and Erismann’ indexes) were calculated on the basis of these parameters. Body composition (absolute and relative amounts of skeletal, fat and muscle components) were determined using Matiegka formula. Results. It was found that the average growth of students in European countries is higher compared to students from Asia (9-10%) and Africa (3-5%). Reliably significant differences (p <.05) in body weight indicators between all ethnic groups were found. Students from India are characterized by very low levels of relative body fat. Most representatives of Egypt (61.4%) and Jordan (50.9%) are characterized by moderately high fat content. For representatives of all other countries, this figure is within the optimal ratio. Conclusions. The obtained results showed that anthropometric and morphometric indicators of students aged 18-25 change statistically significantly depending on the ethno-territorial factor. Thus, the study of ethnic variability of morphological characteristics is of great importance for the individualization of physical training of students from other countries in higher education institutions of Ukraine.

Мета дослідження – виявити характер морфо-функціональних змін в киснево-транспортній системі студентів з різним рівнем кардіореспіраторної витривалості в умовах виконання 12-ти хвилинного човникового бігу. Матеріал і методи. Обстежено 80 студентів (юнаків 17-19 років) для встановлення вентиляційної функції легень, газового складу крові, морфологічного стану еритроцитів, активності перекисів ліпідів, вмісту 2,3-ДФГ і АТФ в еритроцитах. Результати. У студентів з нижче середнього і низьким рівнем кардіореспіраторної витривалості після максимального фізичного навантаження спостерігаються зміни показників “потік-об’єм” на фоні підвищення концентрації лактату і зниження кислотно-лужного балансу, що призводить до збільшення вмісту 2,3-ДФГ в еритроцитах периферичної крові. Висновок. Встановлено, що у студентів з нижче середнього і низьким рівнем кардіореспіраторної витривалості під час виконання 12-ти хвилинного човникового бігу зростання вентиляції легенів відбувається в основному за рахунок збільшення частоти дихання, що призводить до швидкого стомлювання дихальних м’язів і, як наслідок зниження вентиляції легенів і газообміну. При цьому падає рівень оксигенації крові, знижується інтенсивність окисного фосфорилювання і резинтез АТФ, що призводить до появи атипових форм еритроцитів периферичної крові.

Background and Study Aim. Integration processes in education provide for increased mobility of students from different countries. The related change in environmental parameters, cultural and social standards require additional tension in the work of regulatory mechanisms. This can lead to exhaustion of the body's reserve capabilities, disruption of adaptation and loss of health. The purpose of the work is to investigate the ethno-territorial variability of the functional state and adaptation potential of foreign students studying at Ukrainian universities. Material and Methods. Students of the medical university (n = 488, age 18–25) who came to study in Ukraine from different countries took part in the study. Data were obtained from cross-sectional surveys from 2014 to 2019. Anthropometric measures included body length (LT), body mass (MT). Functional status was assessed by Robinson, Rufier, vital capacity and strength indices. Adaptation capabilities and the level of physical condition of students were also determined. Experimental data were processed using the SPSS program. Results. It was established that the vast majority of students had Robinson index values: low and below average (students from Poland, Bulgaria, Jordan, Egypt); below average level (students from Ukraine, Malaysia and Tunisia); medium (students from India and China). Students from Poland, Jordan and Egypt are characterized by the lowest vital capacity index (52.7 – 54.9 ml·kg-1). Among the residents of India and China there were the most students with above average and high levels of vital capacity index. Most of the students (with the exception of students from Malaysia and Egypt) had a power index at the level of average and above average. The Ruffier index for students was: weak level – students from Poland, Bulgaria, Egypt and Jordan; satisfactory level – students of Tunisia, Ukraine, India and Malaysia; moderate level – students from China. The majority (40–44%) of the examined contingent from Poland, Bulgaria and Jordan was in a pre-diagnostic state. There were14–27% of such students among students from Egypt, China, India and Tunisia. There were about 10% of such students among Ukrainian students. From 6% to 11% of all foreign students were in a pre-morbid state. This condition is characterized by a decrease in the functional reserves of the circulatory system. Among Ukrainian students, there were 2.04% of such students. From 2.44% to 7.69% of foreign students had asthenization of regulatory systems; such a state was not observed among Ukrainian students. Conclusions. The obtained results of the study expand the data on the peculiarities of the physiological state of students of foreign countries and their adaptation capabilities. It is important that students with strained adaptation mechanisms or an unsatisfactory level of adaptation are able to reveal high functional capabilities with individualized physical exercises. An unsatisfactory state of functional systems can stimulate students to increase the body's adaptive resources. This contributes to increasing the level of motor activity and improving physical education courses with training according to an individualized educational program.
