“…Високий коефіцієнт Хольцінгера, встановлений для ФРНП, переконливо доводить, що це генетично детермінована властивість вищої нервової діяльності (ВНД) [9], яка доповнює і розширює загальноприйняті типологічні ознаки людини. З'ясування динаміки кровообігу і механізмів вегетативного реагування в умовах вертикалізації тіла в просторі має медичний [10,11] і прикладний аспекти [12], а останнім часом викликає інтерес у наукових колах [13,14]. Важливо встановити те, наскільки рівень розвитку ФРНП може впливати на характер гемодинамічних реакцій, які виникають у відповідь на постуральні навантаження, що висвітлювалося лише у деяких працях [5,15].…”

“…Для поліпшення стартових показників і самого бігу, спортсменові необхідно володіти чималими силовими якостями. Завдяки м'язовим зусиллям, напрузі людина здатна справиться з опором [1,6].…”

“…Третій за значимістю фактор був названий «Антропометричні показники» в нього увійшли такі показники, як зріст (r = 0,774), піднімання тулуба в сід, (r = 0,787), вага, (r = 0,647), Помилки, швидкість простої зорово-моторної реакції (r = 0,633). Даний фактор не менш вагомий, хоча багато авторів [2,5,6] прийшли до висновків, що зріст та довжина нижніх кінцівок, вага не мають істотного впливу на результат в бігу на 100 метрів, в той же час знаючи процес впливу вправ на розвиток тієї чи іншої групи м'язів, можна зробити висновок, що механізм взаємозв'язку розвитку швидкості та сили повинен змінюватися відповідно до зростання атлетів. На початковому етапі антропометричні ознаки та стан провідних функціональних систем важливі при відборі спортсменів з інвалідністю у навчальнотренувальні групи спринтерського бігу, спортивної ходьби та бігу на витривалість, стрибків, метань та багатоборств [8,12].…”

Purpose of the study: to determine the peculiarities of training sprint athletes with disabilities of the musculoskeletal system based on the use of factor analysis of indicators of complex testing. Participants: 15 athletes with disabilities of the musculoskeletal system at the age of 12-14 years, specializing in sprinting. According to the classification for athletes with disabilities - sports and functional classes T35, T36. Research methods: analysis of literature data, anthropometry, testing of physical and functional readiness, testing of psychophysiological capabilities, methods of mathematical statistics. The results show that the indicators of complex testing of athletes with musculoskeletal disorders are divided into five factors "Speed-strength capabilities", "Speed capabilities", "Anthropometric indicators", "Psychophysiological capabilities", "Coordination capabilities". It was found that the leading factors of sprint running among athletes of this category are the development of speed-strength qualities and reaction speed at the start, taking into account the psychophysiological state of athletes, the development of coordination abilities.

Introduction. During the apprenticeship, students training as secretaries are exposed to a complex of professional and industrial factors that cause functional changes in the body. Materials and methods. Thirty 18-19 years girls were divided according to the Eysenck’s psychological types of personality and to Strelau theory into more adapted and less adapted groups, Heart rhythm variability, mental and physical capabilities, the lability of the visual analyzer, and the psycho-emotional state were evaluated at the beginning and the end of apprenticeship. Results. Trend in heart rate variability in the group of less and more adapted cases differed: the total power of the TR spectrum (ms2) decreased by 50.4% in the group of more adapted, by 54.48% in the group of less adapted. The stress index was 126.9% in the group of more adapted, and 131.9% in the group of the less adapted students. After the apprenticeship work, efficiency decreased by 31.3%, the degree of workability increased by 25.0%, mental stability fell by 16.9%. After the apprenticeship, students’ well-being according to the Scores of Well-being, Activity, Mood (WAM) decreased by 24.5% (p<0.001), activity decreased by 21.6% (p<0.001); mood worsened by 7.4%. Before work practice, critical flicker fusion frequency (CFFF) was 43.4±0.3 Hz, and after it 39.6 ± 0.4 Hz (p<0.001). Limitations. The study was limited to a sample of students learning as secretaries, by age, gender and apprenticeship duration. Conclusion. Heart rate variability indicators reflect the tension of regulatory systems in the process of learning practical skills, caused by the occurrence of situations in apprenticeship conditions, which indicates the need of improving methodological approaches to its management, purposeful development of the first key professionally significant functions from the beginning of training, the implementation of physical exercises during the physical education classes, taking into account the specifics of the future profession. A more discernible degree of tension in the regulation processes in the group of less adapted students (a decrease in the total power of the TR spectrum (ms2) by 54.48% and an increase in IN by 31.9% in this group), and the psycho-emotional state of secretaries-referents, requires a personalized approach to apprenticeship managing.
