Physical activity is often considered as an essential component of a healthy lifestyle and is required to be studied in detail. It is especially important to study this issue in reference to the population of older age groups. The aim of the research was to analyse subjective and objective characteristics of physical activity in population of older age groups. Methods of sociological survey, parametric and nonparametric statistics were used in the work. Data on the characteristics of physical activity were obtained on the basis of a study of 1,045 subjects of both genders aged 60 years and older. The participants of the survey did not have any kinds of disability and were not engaged in any sport activities. According to the results of the study, the age of the men and women was the determinant of assessing a level of physical activity. The average level of physical activity prevailed in men aged 60–74 years. Low levels of physical activity prevailed in men aged 75 years and older. Women had mostly low levels of physical activity. Comparison of subjective and objective characteristics of physical activity showed a significant overestimation of subjective characteristics of high levels of physical activity and underestimation of the prevalence of low levels of physical activity in both men and women. As a result of gender comparisons, it was revealed that men aged 60–74 years overestimated their level of physical activity by a fourfold, while women were more objective assessing their level of physical activity.
