Currently, there is no consensus regarding the benefits of physical activity in terms of upper respiratory tract infections (URTIs) among different age groups of children. The number of school students avoiding physical education is on the rise. Children of all ages spend more time on sedentary behavior, eat less nutritious food and spend less time sleeping. All of these concomitant aspects adversely affect the immune system. A coexisting problem of a growing society is a large number of URTIs which is the main reason for general practitioner intervention. The aim of this study is to determine whether there is a correlation between the frequency of respiratory tract infections and the level of physical exercise in a cohort of pre-school children. This will be a cross-sectional, short-term study conducted on a single study population. We aim to recruit four-, to seven-year-old children who will be receiving activity monitoring devices for 24 h a day for 40 days. Daily step count, mean intensity of physical exercise and sleep duration will be measured. Simultaneously, their parents will receive a series of 60 questionnaires, one questionnaire per day, for the daily assessment of upper respiratory infection (URI) symptoms. Our study conducted on a cohort of healthy pre-school children using uniform tools, aims to scientifically establish and quantify the relationship between physical activity and health outcomes over a specified period of time.
