Purpose:to develop and experimentally substantiate fitness technology for students taking into account their individual peculiarities. Material:The experiment was performed by girls (n=51, age 17-20) who were divided into experimental (n=25) and control (n=26) groups. Classes were held twice a week during the year: 66 hours in the hall and 95 hours of independent study. At the beginning and at the end of the study, all students met the control standards, which allowed to determine the level of development of physical qualities and level of physical fitness. Results:8 exercise complexes were developed to implement our fitness technology. Complexes were taken into account: interests, age, individual characteristics and level of physical fitness of students. At the first lessons the loading was about 45-50%. In the future, the loading increases to 70-75% of the total time of classes. Conclusions:When constructing fitness technology using varieties of fitness it is necessary to take into account: the type and nature of exercises, the volume and intensity of exercises, the number of repetitions and the amount of weight, the frequency of training sessions and the duration of work, intervals of rest, the number and alternation of exercises.

“…The reasons for the unsatisfactory state of health of schoolchildren of secondary schools and the level of their physical preparedness is the lack of scientifically substantiated system of physical education of schoolchildren [3,33,42]. This is due to the fact that the integral concept of this system has not been developed, the ways of its restructuring have not been defined [3].…”

“…Physical culture is a means of upbringing and improving the physical training of schoolchildren. Physical culture is also: the main factor in the restoration and strengthening of health during the formation and formation of the body; a source of general and mental performance improvement [36,37,42]. The state of health of children and adolescents should be considered as a criterion for their readiness to perform labor and social functions [8,15,30].…”

Purpose:to analyze the state of physical education in secondary schools of Ukraine and to observe hygienic requirements during physical education lessons. Material:the study was attended by schoolchildren (n=40, age -12-13 years) and schoolchildren of specialized sports classes (n=40, age -14-16 years). Studied: the level of physical health; functional state of the respiratory and cardiovascular systems; the state of energy supply of children's organism; the influence of mobile games on the functional capabilities of the body of children. To study the effects of physical exercises on the development of the muscular system of children, excretion of creatinine with urine was studied. Results:high levels of physical and functional status of young players are noticed. These data are significantly higher than similar data from their peers from non-sports classes. In the course of systematic training and competitions, excretion of creatinine decreases at the end of the season to 0.8 g/l. These changes point to a decrease in energy resources and are consistent with a decrease in the rapid qualities of young players (as a measure of overall physical fitness). In this group of pupils, there were 2-4% lessons in the classes: mostly because of colds. In schoolchildren of ordinary schools, indicators of physical development and functional status were significantly worse. The indicators of the lung capacity were 3500-3800 ml. The distance of 30 m children ran for 5,5±0,4 seconds. The index of the brush dynamometer was 35±1,8 kg. The results of the recovery of the heart rate after the metered loading were from 2 to 3 minutes. There is a shortage of body weight in 12% of schoolchildren. There is an overweight in 1,8% of schoolchildren. Conclusions:in the structure of children's morbidity a high level of respiratory diseases, gastrointestinal tract, and eyes is allocated. Therefore, when taking physical training, such data should be taken into account. It is also necessary to take into account the level of individual somatic health, which leads to a safe area of intense motor activity.

“…Equally important is the use of the competitive method in training athletes [21], in physical education classes for students [20,29,35], and schoolchildren [18,24,37]. The effectiveness of such occupations depends on psychological factors [26,44], the emotional state of athletes [34], the attractiveness of physical exercises [32,33].…”

Purpose:to determine the efficiency of the cyclist in various tactical options. Material:In the experiments participated athletes (n = 6) of high qualification (mean age -19.8 ± 1.3 years, mean weight -71.4 ± 3.5 kg). As a model of the individual pursuit race at 4 km, a five-minute pedaling on the bicycle ergometer was used. Series of loads was set on the modernized mechanical bicycle ergometer "Monark". The five-minute bicycle ergometer test is similar to the individual pursuit race at 4 km: according to the time of the exercise; on the frequency of pedaling (110-120 rpm); on the frequency of heartbeats. Results:Tactical variants in the pursuit race at 4 km are considered. The total work in a free test was on average 106.38 ± 3.57 kJ. The operating energy consumption is on average for 379.0±16.1 kJ. The operating efficiency (economy) of the exercise attained on average for 28.0 ± 0.75%. This corresponds to the effectiveness of aerobic work of moderate power. The ratio of aerobic and anaerobic contributions to the provision of work was 77.3 and 22.7%. The smallest work was done in a test with step-increasing power. The athletes performed the closest work to the given job in the test with a variable (±15%) operating mode. The shortfall in it was on average for 0.46%. The absence of reliable differences in the economics of the work did not allow us to identify a rational variant of power distribution for an exercise lasting 5 minutes. Conclusions:Tactical options in the pursuit race for 4 km depend on the features of the power systems of the rider. When optimizing tactics, it is necessary to select an individually optimal variant of the distribution of forces at a distance.
