The study included children referred by their state of health to the main medical group (n=91). The average age of boys amounted to 9.6±0.05 years, and of girls - 9.5±0.05 years. The set of methods suitable for the study of school-aged children’s physical working capability at the wide range of accessible tensions was studied. The arrangement of the study met demands of Helsinki declaration. During the study 5 main factors determining physical working capacity structure in 9-10 aged children under the vast range of accessible tensions were found out. All the children were certainly health, went in for physical exercises according to commonly accepted program and did not attend sport sections. In the work there was used the complex of methods suitable for the study of the physical performance of schoolchildren in the large range of available loads. During the study there were selected 5 main factors determining the structure of the physical performance of children aged of 9-1-0 years. It is shown that boys’ and girls’ against background of the preservation of the common structure of the performance contributions of considered factors to the summarized dispersion of the sample, and physiological indices included in to the pattern of specific factors and their weight coefficients are distributed in various ways. Boys aged of 9-10 years were established to exceed girls by physical working capacity in all ranges of available loads. Meanwhile the greatest number of significant differences was identified concerning the variables characterizing working capacity in the moderate and high power relating with mainly aerobic and mixed aerobic-anaerobic power supply of muscular activity. Indices of aerobic capacity are characterized with the most differential “sensibility” in comparison with other energy criteria of the working capacity. The results of the study can be used in the solution of practical tasks according to hygienic rating and control of the value of physical loads of different relative power during the process of physical education of children aged of 9-10 years.

The analysis of scientific and educational-methodical works which cover methods and means of restoration of physical working capacity of experts of various specialties is carried out. It was stated that the official activity of police officers involves significant physical and psychological stress. It is substantiated that a high level of physical performance is one of the conditions for quality performance of functional duties and contributes to less manifestation of the effects of fatigue. The specifics of physical activity in the conditions of police service necessitate the search for tools that contribute to the rapid and full recovery of physical performance of law enforcement officers. It is established that the quantitative manifestation of the level of physical fitness of the specialist is necessary for the assessment of the functional reserves of the organism during the organization of physical education of the population; in sports, during the selection, planning and forecasting of training loads of athletes; in adaptive physical education; to determine the motor mode of patients in clinics and rehabilitation centers; forecasting the course of diseases. The specifics of application of pedagogical, medico-biological and psychological means of restoration of physical working capacity of policemen are characterized. It is argued that in the conditions of professional training of police officers, pedagogical tools are key in optimizing the recovery processes, as they are based on the body's natural ability to self-healing. Medico-biological and psychological means of recovery are considered additional only if the rational construction of the educational process. These tools help to increase the body's resistance to stress, accelerate the reduction of acute manifestations of general and local fatigue, effective recovery of energy resources, accelerate adaptation processes. It is determined that restorative means should be used in accordance with the type and specifics of physical activity, taking into account the individual characteristics of the police officer. When choosing the means of recovery, a rational combination of means of general and local action becomes important.

The main issues related to the assessment of the functional state of the body and the physical performance of the serviceman are considered. The review of modern methods for assessing the functional state and physical working capacity of a person in sports medicine and the physiology of military labor both in Russia and abroad is presented. The choice of the methods allowing to unify approaches to an estimation of military-professional working capacity in stationary and field conditions is proved. It is established that in the scientific research practice of military medical specialists, it is expedient to evaluate the functional state of the serviceman’s organism and its physical working capacity under loads associated with both dynamic and static muscle work. It is determined that ergospirometry is the most acceptable method of assessing the functional state of the body and the physical performance of servicemen in the process of performing dynamic work. It is noted that with the help of ergospirometric testing, it is possible to predict the physical performance of a serviceman and the duration of its preservation at a given level, replacing or supplementing most standard load tests, which is a weighty argument in favor of its choice as a «gold standard». It has been established that to evaluate the functional state of the body and the physical performance of servicemen in the process of performing static work, the main method is stabilometry. A significant number of available stabilometric techniques, including those using biofeedback, significantly expands the possibilities of diagnosing the functional state of the body of a military specialist. It is determined that the most acceptable method for assessing the impact of dynamic loads on the locomotor system of a serviceman is the use of the “motion capture” technology. The main advantages and disadvantages of modern means and methods of studying the functional state and physical working capacity of a person are revealed. The modern hardware and software complexes used to solve scientific research problems of biomedical orientation are listed.
