Purpose: the search of the effective means of aquafitness for the correction of the functional state of women in the age of 35-45. Materials and methods: 1) theoretical analysis and consolidation of data of the scientific and methodological literature; 2) estimation techniques of the morphofunctional state; 3) bioimpedance analysis; 4) pedagogical testing; 5) expert assessment; 6) questionnaire survey; 7) pedagogical experiment; 8) methods of the mathematical statistics. Results: the experiment was implemented from 2016 to 2019. 256 women, who were just starting to do aquafitness, took part in it. They were subdivided into two groups: control group (128 women) and experimental group (128 women). Examinees of the control group had 40-minute workout 3 times per week: twice a week-aqua aerobics and once-swimming. Examinees of the experimental group did aquafitness 3 times per week for 40 minutes according to our developed method of integrated use of aquafitness means. Unique water workout programs, nutritional recommendations and its control were developed for the experimental group. The aquafitness' effective means were combined by us in 9 workout programs, which were distributed throughout training courses of the women in the age of 35-45. Conclusion: During the pedagogical experiment, the effectiveness of the author's method was established, which was expressed by more significant positive changes in the results in the experimental group compared to the control group in terms of functional status, fat and muscle components of the body.

Purpose: to develop and experimentally confirm the structure of training cycles, training load and sports results with regard to the biological rhythms and functional condition of powerlifters. Material: the study involved qualified powerlifters (n = 40). The diagnostic procedure was performed on the Omega hardware complex. Ostberg questionnaire was applied to determine the athlete’s chronotype. According to the results of the questionnaire, athletes were divided into morning, evening and mixed chronotypes. In the experimental group (N1, n = 20), intensive training was conducted at the peak of the biological rhythm. Medium and low-intensity training was performed in the phase of reducing the biorhythms activity. Standard training was performed in the control group (N2, n = 20), without regard to chronotypes. Results: it was determined that the application of non-standard means of athletes training at the peak of the biological rhythms activity and in the rising phase of the biogram significantly influences on the increase in maximum strength results. Non-standard means include Crossfit training and a reverse pyramid (the maximum weight is applied at the beginning of the training, in the subsequent approaches the weight reduces, the number of repetitions increases). It is determined the significant differences between groups in the control exercises: hanging pull-up/chin up, parallel bar dips, hanging on the crossbar. Conclusions: the training of qualified powerlifters should be based on their chronotype. The main mean of the training process optimizing of athletes should be a biogram, reflecting the physical, emotional and intellectual biological rhythm.

Purpose: bioimpedance analysis of body composition for the different age groups of population in order to choose an individual program of physical exercise. Materials and methods: Research was done in Plekhanov Russian University of Economics (Russia, Moscow) using body composition analyzer «InBody 720» and functional diagnostics «Esteck System Complex». Research takes into account physical indicators of 359 females and 460 males from 18 to 74 years old who do not practice any physical activities or do it occasionally.Results: The study identified substantial increase in fat component of women`s body in a period of 29-34 years old-39,6%, in 46-55 years old it is critically increasing up to 51,2%. Females start feeling muscle weakness in period of 35-45 years old. In males group dynamic of fat component is on an ordinary level and even lower in a young age (18-28)-10,3%, 29-34 years old-18%, 35-45 years old-21,1%, 56-74 years old-24,4%. Most of the participants have satisfactory functional condition-70-90 points (max. 100). However, a low reaction level on an ordinary physical exertion was identified, as well as a poor level of reserved capacities of cardio-vascular and respiratory systems. Conclusion: To plan a fitness program it is necessary to consider such characteristics as age, sex, individual index of body composition and functional condition, individual preferences in types of physical exercises, indexes of hearth rate and blood pressure. While planning fitness training, it is necessary to take into account proportion between fat component and muscular component («fitness-points»), balance of energy.

Purpose: improving the performance of students with weak health by the means of fitness based on unit, person-centred, and systematic approaches. Materials and methods: students with weak health took part in the research (n = 460, age 18.0 ± 0.82 years). The experiment lasted for 9 months. With students of the control group (N1, n = 230 in which 150 are girls and 80 are boys) traditional lessons were held in accordance with the current programme of physical education. For the experimental group (N2, n = 230 in which 150 are girls and 80 are boys) blocks (module) in athletic gymnastics, water fitness, and aerobics were created with detailed competence. Electronic educational resources with video sets of special exercises were made and put into practice taking into account the underlying medical condition. Each unit contains goals and ways of achieving them. Person-centred approach included measuring physiological parameters. The systematic approach consisted of the organising of process of physical education with systematic monitoring of the functional state of the body. Results: by monitoring physical fitness by exercise testing, it was found out that all research subjects had improved their results. However, students in group N2 had achieved much higher figures than students in group N1. The noticeable increase in static, strength and coordination endurance was noted. Conclusion: the research has proven the efficiency of improving the process of physical education for students with weak health based on unit, personally oriented and systematic approaches.
