to establish the integrated effect of training sessions using elements of aqua fitness and interval hypoxic training on the special physical fitness of swimmers. Material:young swimmers participated in the study (n = 64, age 11-12, sporting experience -2-3 years). The research was carried out in stages: before the experiment began, and then in 8, 16 and 24 weeks later. Frequency of classes in all groups was 6 times a week. Results:the ability to work in anaerobic alactatic, lactate and aerobic energy supply zones was studied. It was established that such training sessions help to improve the performance and capacity of the anaerobic alactatious system. The feasibility of such combination is proved by the growth of performance indicators in areas of aerobic, anaerobic alactatic and lactate energy supply. Conclusions:The feasibility of such training sessions is explained by: minimizing the negative impact on the children's body of exercises on the development of force in conditions of the aquatic environment; improving the functional capabilities of the body.

Purpose: to identify the features of the impact of aquafitness training on aerobic and anaerobic productivity of women 25-35 years. Material and methods: The study involved women aged 25-35 in the number of 41 people. For 24 weeks, the subjects were training in an aquafitness program. Training sessions of aquafitness were aerobic and strength. Anaerobic alactate productivity of the organism was determined by the Wingate anaerobic test WAnT 10. Anaerobic lactate productivity of the organism was determined by the Wingate anaerobic test WAnT 30 and bicycle ergometric test by the method of A. Shogy, G. Cherebetin. The threshold of anaerobic metabolism was determined by bicycle ergometric test F. Conconi et al. in the modification of  Yu.M. Furman. The aerobic productivity of the organism was investigated according to the Vo2 max index determined by the method of V.L. Karpman. Absolute and relative indicators were determined for all tests. Results: Aquafitness is an effective means of correcting the indicators of functional preparedness. The combination of strength and aerobic training in the aquafitness program provides an increase in aerobic productivity, anaerobic lactatic productivity and anaerobic alactatic productivity. Under the influence of training according to the aquafitness program, an increase in all indicators of functional preparedness was revealed. The power of anaerobic alactate productivity of the organism determined by the relative indicator WAnT 10 increased with a statistically significant difference on the level (t = 5.07; p = 0.000). The power of anaerobic lactate productivity of the organism determined by the relative indicator WAnT 30 increased with a statistically significant difference on the level (t=4,68; p=0,000). The power of aerobic productivity of the organism determined by the relative indicator VO2 max increased with a statistically significant difference on the level (t=2,77; p=0,007). Conclusions: Aquafitness is an effective means of correcting the indicators of functional preparedness. The combination of strength and aerobic training in the aquafitness program provides an increase in aerobic productivity, anaerobic lactatic productivity and anaerobic alactatic productivity.

Purpose: the identification of features of the maximum oxygen consumption of women in the first period of mature age and connection with body structure component. Material: 22-35 years old women (n=210) have participated in a research. Results. It was determined that women with endomorphic and mesomorphic somatotype prevail according to the absolute measure VO2 max. They have large body weight and higher percentage content of the muscular component. The women with low body weight and low values of fat component prevail according to a relative measure VO2 max. Large body weight in women of endomorphic, endomorphic and mesomorphic somatotype stipulates low values of a relative measure VO2 max. It is indicated by the high degree of the return correlation between a relative measure VO2 max and body weight. Conclusions. The relative measure VO2 max is considered more informative as its dependence on body weight is leveled. The obtained data indicate the advantage according to a relative measure VO2 max of women with low body weight somatotype (ectomorphic and balanced). Such feature is explained by authentically low percentage content of the fat component in women.

Background and Study Aim: The somatotype determines not only physical development, but also the functional capabilities of the organism. Investigation of the correlation relations between the component of body and VO2 max will reveal the influence of each of the components on the aerobic capacity of men in the first period of mature age. The aim of the work – to detect the peculiarities of manifestation of maximum oxygen consumption of men with different somatotypes and to investigate the relationship with the component composition of the body. Material and Methods: The study involved 150 men aged 25-35 years. The somatotype was determined by the Heath-Carter method. The component composition of the body was determined by the bioelectrical impedance method. The VO2 max indicator was determined, metered loads were performed on a bicycle ergometer. A correlation analysis of the absolute and relative VO2 max values with the fat and muscle components of the body was performed. Results. A high degree of inverse correlation between the relative VO2 max indicator with body mass in men of mesomorphic somatotype was established and a high degree of inverse correlation between the relative VO2 max indicator with body mass and BMI in men of endomorphic-mesomorphic somatotype. Conclusions: For representatives of the mesomorphic and endomorphic-mesomorphic somatotype, a larger body mass and a high degree of correlation between body mass and relative VO2 max indicator are characteristic. For representatives of the ectomorphic and balanced somatotype, a smaller body mass and a lower degree of correlation between body mass and relative VO2 max indicator max are characteristic.

To establish the complex influence of aqua fitness exercises and endogenous-hypoxic breathing techniques on the physical preparedness of women 30-49 years old. Material: The study involved 41 women who had no previous experience of systematic physical education. 2 groups were formed: MG1 (n = 20, age 30-36 years old); MG2 (n = 210, age 37-49 years old). The experiment lasted for 24 weeks. At classes, aqua fitness was applied to the method of endogenous-hypoxic respiration. At the various stages of the study (8, 16 and 24 weeks) it was examined physical preparedness of women. Frequency of classes was 3 times a week. Results: Indicated in the need for dosage loading, taking into account the age factor and the level of physical and functional preparedness of women. It was established that classes contribute to improvement: explosive force; active flexibility of the spine; force dynamic endurance of the muscles of the lower extremities; speedstrength endurance of muscles of the abdominal press; power static endurance of muscles of the back, neck and buttock muscles; overall endurance. Conclusions: Aqua fitness exercises together with the endogenous-hypoxic respiration method contribute to the improvement of the physical fitness of mature women. For women of 30-36 years old, improvements in physical fitness were reported earlier compared with older women.
