Abstract

This research aimed to obtain objective assessments of the physiological parameters of external respiration using the modified Skibinskaya index in students with different levels of physical activity during their period of study at the university. The author conducted a prospective study of the physical health of 615 students (255 males and 360 females) of the Arzamas Branch of National Research Lobachevsky State University of Nizhny Novgorod aged 17–22 years using the Student Health Diary, which was applied for the anthropometric screening of the university students on the annual basis. It was found that during the period of study at the university, the majority of students show an improvement in their external respiration function due to physical activity: the higher the activity, the greater the improvement in physiological indicators. A quarter of fourth- and fifth-year students experience a decrease in physical activity and, as a result, a decrease in external respiration indicators, which is explained by the absence of physical education classes during this period of study. Thus, their respiratory system loses its accumulated functional reserves. In order to objectively evaluate the physiological characteristics of the respiratory system, the author developed a rating scale for Skibinskaya’s test, taking into account the region-, sex- and age-specific standards of physical development, and performed a comparative assessment of the measuring results, reflecting the actual functional capacity of the students’ external respiration and their bodies’ resistance to hypoxia. The results obtained argue in favour of the introduction of disciplines or electives aimed at creating a healthy lifestyle and raising the level of physical activity among fourth- and fifth-year students.
