    Typological belonging of athletes and evaluation of the body's aerobic performance when doing competitive sports

    The paper deals with the questions of search of dependence of the functionality of the body upon anthropometric typology that can serve as a criterion for the development of individual mechanisms of adaptation in muscle activity. The experiment was conducted in longitudinal mode for 3 years in the Laboratory of Physiology of Child Development at Research Institute of Complex Problems of the Adyghe State University. The contingent of the examined included young athletes from youth sports school of Olympic reserve and skilled athletes of the Institute of Physical Culture and Judo of Adyghe State University in Maikop, Russia. The total number of surveyed was 80 people aged 10 to 20 years. Somatotypological approach was proposed to solve the problem of individualization of training loads. It is inferred that the main risk group in the framework of the basketball and football training consists of representatives of brachymorphic body type, who have the lowest rates of VO2Max, whereas the highest were revealed between the repre-sentatives of different somatotypes under aerobic productivity of an organism, determining individual typological dif-ferences in general endurance and adaptation capabilities of the athletes’ organism.

    Symmetry of kinematic structure of locomotions of the person

    An optical system of the three-dimensional video analysis of movements is used to establish that at the athletes who are going in for powerlifting the spatial-temporal order of joint motion when performing squats is displayed in the form of a dynamic symmetry and dynamic asymmetry. A dynamic symmetry of joint motion is characterized by kinematic structure at which the spatial-temporal order of angular movements during a joint extension is the inverse spatial-temporal order of angular movements during flexion. Violation of a dynamic symmetry is observed at building up the weight of more than 60% of maximal. A dynamic symmetry of angular movements in talocrural, knee and coxofemoral joints in the course of an ontogeny is formed heterotropously. The obtained data will allow development of a technique of evaluation test of realization of the person’s movement skills on the basis of the systemic-symmetric approach, as well as a technique of perfecting natural locomotions in the course of sports perfecting and in the course of ontogeny.

    Hemodynamic changes after the combined frequency impact on the human body

    The study examines the combined effect of neuroinformation signals of different frequencies modulated by pulse hypoxia on the effector activity of the cardiovascular system. The aim of this work is to study the effect of these signals on the peripheral vascular resistance, systolic volume of the heart and the average dynamic arterial pressure. We have found that during the frequency impact the systolic volume, the contractile myocardium force and the driving force of blood flow increase. Activation of effectors of cardiovascular system brings blood flow to conformity with metabolic needs of organism. Adaptation to hypoxia and adverse climatic and environmental factors is generated under the influence of neuroinformation signals. The proposed mode of frequency impact is developed by M.T. Shaov and data on this research are few in the literature.

    Anthropogenically changed microflora of the soil ecosystem as possible link in the chain of opportunistic infections

    An analysis is made of statistical processing results of bacteriological researches of soils in residential zones of Yakutia. As a result of increasing anthropogenic load on the ecosystem, biological activity of the soil reduces and the true representatives of soil microbiocenoses decrease, which in turn, increases the negative impact of soils on human health. Against the background of reduced findings of indicator bacteria (enterococci and Escherichia), in Yakutia soils more common are toxic species of fungi of the genus Fusarium, Mucor and Aspergillus, which also can cause diseases transmitted through environmental objects. It is inferred that anthropogenically changed microflora of the soil ecosystem shapes the state of health of the population and the microbial contamination of the soil and other objects of a surrounding medium is a possible link in the chain of opportunistic diseases.

    Numerical analysis of the effect of radiation damping on the angular distribution of synchrotron radiation of the spectrum individual harmonics

    The numerical analysis is carried out to study angular dependence of intensity of harmonics of the synchrotron radiation (SR) considering radiation damping when the Lorentz force is much greater than the force of a radiation sliding friction during the charged particle motion in a magnetic field. The paper shows the difference in behavior of angular distribution of integral intensity of the SI and angular distribution of individual harmonics that confirms the theoretical result obtained earlier for the SI not taking into account the effect of radiation damping. It is confirmed that as distinct from integral intensity of the SI, spectral intensities tend to a deconcentration in the orbit plane. Radiation damping slightly deforms angular distributions of intensity of the SI of individual harmonics.

    Searching for various ways of the physical problem solution as means to develop students’ cognitive abilities accoding to FGOS of secondary education

    The paper deals with the organization of the educational process aimed at the development of cognitive abilities of students according to FGOS of secondary education, in particular a technique is provided of searching for various ways of the solution of a physical problem. A problem about movement of the straightforward conductor in a constant homogeneous magnetic field was used as an example to show the principles of the organization of classroom hour in physics promoting development of abilities of the person, formation of skill to investigate and analyze the various physical phenomena. It is noted that the modern textbooks on physics for pupils of high school give only the shortened variants of solution without careful analysis of the occurring phenomena. In a higher school course of the general physics this problem is only an element of more complex problems therefore discussion of details of the solution, in es-sence, drops out of educational process. It is inferred that there is a need to eliminate the arisen didactic defect. Prob-lem solutions in each of three considered cases are analyzed in detail.
