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.
The work was carried out on 36 clinically healthy young basketball players aged 17-21 years old, training in the basketball section for at least 3 years. The created control group consisted of 26 clinically healthy young men aged 17 to 21, who had not previously been involved in any kind of sports. In the study, the examined were subjected to ultrasound examination using an SSD-80 "Aloka" device (Japan) with an assessment of the morphological and functional characteristics of the heart. The statistical analysis of the obtained results of the study was carried out using a personal computer using the Student's t-criterion. Some signs of the development of left ventricular muscle hypertrophy were found in young basketball players. At the same time, the basketball players retained the optimum volume of the left cardiac ventricle. The youth basketball players also had a higher diastole rate compared to the control group. Regular basketball training can strengthen the body. They lead to an increase in the muscle mass of the left ventricle, which increases its functional potential and provides an optimal blood supply to internal organs.
Under observation were taken 39 young men studying at the university, throughout their lives, who had low muscle activity and started systematic volleyball training 3 times during the week. The control group included 35 young men studying at the university, who for at least the last 2 years systematically participated in volleyball training at least 3 times a week. During the study, traditional biochemical, thematic, and statistical methods for obtaining scientific information were used. After six months of regular physical training in the blood of young men, there was a normalization of the content of products synthesized from arachidonic acid, a decrease in the content of cholesterol molecules, and acyl hydroperoxides in the erythrocyte membranes with an increase in the number of phospholipids. By the end of the observation in the blood of young men who started volleyball training, there was an increase in the number of discoid erythrocytes and a decrease in the content of erythrocytes with a changed shape. It can be assumed that with an increase in the level of muscle activity due to systematic volleyball training, previously physically untrained young men develop optimization of the surface characteristics of erythrocytes, which can facilitate microcirculation and metabolism throughout the body.
The high level of development of modern medicine cannot reduce the growing prevalence of various types of pathologies and injuries in people of different ages. Recently, a fracture of the lower jaw is often found among student youth. In this regard, the issue of improving the rehabilitation of young people with this type of injury is relevant. The importance of this problem is associated with the high frequency of such an injury and the increase in the number of complications developing against its background in the head and neck region. Despite the efforts of medicine, these patients still have a high risk of developing persistent jaw dysfunction and the danger of maintaining a "cosmetic defect" throughout their lives. Regular physical education should be of great importance in the development of rehabilitation options for a fracture of the lower jaw. It provides a good healing effect, especially when combined with several physiotherapeutic and psychotherapeutic effects. However, there is still a need to accelerate the rehabilitation process and increase its effectiveness after a fracture of the lower jaw, which requires the search for new directions for further scientific research on this issue.
Regular execution of movements while in the aquatic environment, ensuring the swimming process, heals the entire body. As a result of regular swimming, many positive changes occur in human tissues. As a result of systematic swimming training, a functional improvement of all human internal organs occurs. Frequent swimming training improves health and enhances the severity of physical and mental performance. Swimming strengthens the heart, improves vascular function, trains skeletal muscles, activates immunity, stimulates the breathing process, neutralizes most of the effects of stress, and tones all body tissues. Swimming is considered as a dosed physical activity that forms a stable positive emotional background and leads to the recovery of the whole organism. In the central nervous system, during the performance of motor actions in the aquatic environment, a more pronounced intensification of life processes occurs than during the performance of physical exercises on land. This effect is possible due to the stimulation of skin receptors with water. Private swimming training stimulates the autonomic nervous system. Swimming weakens the activity of its sympathetic part and increases the biological capabilities of its parasympathetic component. This contributes to the normalization of peripheral vascular tone, optimizes heart rate, lowers blood pressure, stimulates gas exchange processes, contributing to an increase in oxygen content in the blood, and intensifies metabolism in all cells.
Предлагается способ оценки эффективности физической подготовки студентов вузов гражданской авиации. Выбраны обобщенные критерии физической подготовленности на основе функциональных проб и двигательных тестов. Профессиональными могут быть показатели, которые имеют высокую корреляцию по отношению к оценке уровня общей физической подготовленности и являются ведущими показателями освоения профессии будущих специалистов авиационной отрасли. Методика анализа должных норм физической подготовленности представлена двумя этапами. На первом этапе определяется градиент динамики результатов применяемых упражнений, которые различаются весовыми коэффициентами профессиональной компетентности. Второй этап представляет собой прогнозирование должного уровня физической подготовленности студентов на заданные временные параметры (должные нормы для периода обучения). Основу проверки составляет определение уровня и характера такой подготовленности путем практического выполнения двигательных действий. Оптимальность проверки предполагает, с одной стороны, стимулирующие характеристики занятий физическими упражнениями, а с другой -совокупные показатели влияния специальных упражнений на интегральное состояние студентов. При проверке физической подготовленности обучаемого совокупностью тестов, предъявляемых в заданной последовательности, из определенных упражнений была составлена блоксхема модели оценки физической подготовленности студента. Ключевые слова: физическая культура, физическая подготовленность, студенты, гражданская авиация.
