The prevalence of sharp respiratory diseases is very wide. The disease affects all age groups of the population. It is known that every adult man per year is sick of a sharp respiratory disease from 2 to 4 times. This forms a greater danger of complications in the lungs-free and creates a large number of cases of disability, and therefore gives material damage. The effect on the organism of the causative agent of acute respiratory viral infection can vary significantly depending on the etiology, age of the patient, the state of his immune system, and the presence of concomitant diseases. Against the background of the height of the disease, symptoms of intoxication prevail chills, a sharp headache with overwhelming localization in the frontal region and temples, pain in the muscles and joints, pain when the eyeballs move or when pressure is applied to them, lacrimation, severe weakness, and fatigue. With acute respiratory disease, intoxication, hemorrhagic and respiratory syndromes are developing. The relative benignness and short-term flow of this disease leads to the fact that the majority of patients do not seek medical attention. For this reason, it is far from always possible to diagnose the species affiliation of the pathogen.

For residents of all northern countries, a great biological hazard is the cold, which negatively affects all the functions of the body. Fatal outcomes when exposed to the cold are very often associated with alcohol consumption. At the same time, the number of survivors, but those who become disabled due to supercooling, seriously exceeds the number of dead. In the case of progressive hypothermia in the human body, a number of negative reactions occur, leading to a drop in temperature, depletion of physical reserves of the heart, liver, muscles, breathing and heartbeat, reduce the tone of vessels and reduce the blood flow rate. All this leads to stasis of blood, oxygen starvation of tissues due to the excessive connection of oxygen with hemoglobin. Under the influence of cold, frostbite most often occurs, manifested by reactive inflammation and necrosis. The main cause is the cooling of the body surface and the thermoregulation disruption. In the course of the emerging necrosis, the role of tissue edema is great. In addition, with the influence of cold, the vessel spasms develop, the bloodstream slows down and the tissue ischemia is growing. Physical rehabilitation after the action of the cold should be carried out very actively. Its success is associated with the complexity and perseverance of the use of therapeutic physical culture, massage, and various physiotherapy.

The development of coronary atherosclerosis leads to the formation of coronary heart disease, which threatens early death or disability. Such patients need a shunt operation to restore blood flow in the vessels of the heart. After this operation, patients need complex rehabilitation, which has strict stages. To expand the physical activity of patients after coronary bypass grafting, a system of motor activity consisting of 7 steps is used, modified for use in Russian clinical conditions for the rehabilitation of patients after shunting of blood vessels supplying the myocardium. This technique involves the use of seven stages of motor activation of patients, through the use of complexes of medical-physical culture with a gradual strengthening of gymnastic exercises, through the use of training using exercise bikes and dosed walking in open areas, built on the principle of "from simple to more complex." The first two stages of motor activation are applicable to patients immediately after coronary artery bypass grafting at the stationary stage; 3-5 stages of motor activation are physiologically justified for in-patient rehabilitation; the 6-7 steps of motor activation are applicable to patients on outpatient rehabilitation.

The parameters of erythrocytes largely determine the processes of blood movement through small vessels and metabolism in tissues. The study included 37 young men who during the past life showed low muscle activity and, at their own request, started regular swimming lessons 3 times a week. The control group consisted of 42 young men who, before being included in the study, went in for swimming for at least 5 years at least 3 times a week. Traditional hematological, biochemical and statistical research methods were used. Weakly physically trained young men before the start of swimming had an increased amount of altered forms of erythrocytes in the blood, which negatively affected their microcirculation. After six months of swimming in the blood of young men, the level of arachidonic acid derivatives normalized, the content of cholesterol molecules and acyl hydroperoxides in erythrocytes decreased, and phospholipids increased in their membranes. In the blood of swimmers, the number of discoid erythrocytes increased and the number of erythrocytes with an altered shape decreased. The control group, which had a long experience in swimming, was characterized by a high preservation of the shape of erythrocytes and an optimum of biochemical parameters taken into account. By the end of the observation, the novice swimmers showed the output of erythrocyte and biochemical parameters to the level of the control group.

Training within the framework of adaptive sports and especially handball helps to significantly increase the level of adaptation to social conditions in people with hearing system pathology. Regular practice of this sport increases the accuracy of motor acts and stimulates general adaptive capabilities. The study involved 31 male teenagers aged 13-14 with sensorineural hearing loss of I-II degree. Of these, two groups were formed: the observation group (14 adolescents), who began to engage in adaptive handball, and the comparison group (17 adolescents), who continued to engage in physical education at school. The results of the annual medical examination, the results of functional tests and control standards of physical fitness were used. The results were processed using the Student's t test and correlation analysis.Regular physical trainings within the framework of handball allowed to increase the coordination-motor potential and stabilize the vestibular-dynamic stability of adolescents. They increased their physical readiness and the accuracy of their motor actions fulfillment in the conditions of play and in everyday life.Regular training in adaptive handball in adolescents with sensorineural hearing loss increases coordination abilities, speed capabilities, strength qualities and general endurance.
