Vasyleha P. Features of Motor Activity and Cardiovascular System Functioning in Children Aged 7-9 Who Have Experienced Acute Respiratory Viral Infections and Covid-19 (case Study of Sumy Region)

Several aspects related to the analysis of physical activity indicators in children during the spread of Acute Respiratory Viral Infections (ARVI) remain underdeveloped. It is worth noting that quarantine measures such as remote education, the absence of regulated physical activities, and isolation have a negative impact on the level of physical activity in children. Thus, the spread of ARVI infections has both a direct and an indirect impact on children's physical activity. The direct impact is characterized by the course of the illness and a significant reduction in the level of physical activity due to pathological changes in the body. The indirect impact is caused by the implementation of quarantine restrictions and a reduction in regulated physical activity. This suggests that the spread of ARVI infections affects children's physical activity levels both directly, through the course of the illness, and indirectly, through the introduction of quarantine measures and the reduction of regulated physical activities. The analysis of this problematic field has become particularly relevant due to the Covid-19 pandemic. On January 30, 2020, the World Health Organization (WHO) declared a Public Health Emergency of International Concern in response to the emergence of a new coronavirus disease, which was named Covid-19, caused by the SARS-CoV-2 virus. The pandemic lasted for over three years, and it was only on May 5, 2023, that the WHO declared its end. As a result, Acute Respiratory Viral Infections (ARVI) represent one of the most pressing medical and socio-economic problems in the country. This is due to the high prevalence of these diseases, their complex course, severe complications, and mortality rates. ARVI ranks high in the structure of childhood diseases. Virtually every child experiences ARVI or the flu annually. There is a noticeable lack of scientific research on the impact of ARVI on indicators of physical activity and the functioning of the cardiovascular system in children. The purpose of this work was to investigate the impact of ARVI and Covid-19 on the cardiovascular system and physical activity of children aged 7-9. To achieve this goal, the following methods were used: Data extraction from primary medical records. Commonly accepted methods for studying the functioning of the cardiovascular system: heart rate, systolic and diastolic blood pressure, pulse pressure, CO, and SV. Commonly accepted state tests and norms for assessing the physical fitness of the Ukrainian population: a 30-meter run, shuttle run, dynamometry, trunk flexion, and standing long jump.
