Objective and structure of the study. For preschoolers, school and university students, the optimal level of motor activity is a physiological need and an important component of their healthy lifestyle. In this view, we conducted a comparative analysis of the levels of their physical development and physical fitness at the early stages of ontogenesis (n=10,618). The monitoring technologies enabled to detect a certain correlation of changes in the respondents’ rates.
When comparing the growth rates of physical development and physical fitness of the preschoolers, the maximum increase in terms of most indicators was observed at the age of 5-6 and this trend was typical of the children of both sexes.
The schoolchildren were characterized by the alternating periods of growth of physical development and physical fitness rates. The physical development indicators in the girls increased rapidly at the age of 12-13; moreover, in their development they significantly outpace boys (13–15 years). Among boys, the maximum increase in the physical fitness rates (8-11 years) takes a longer period of time, especially after 14 years. In girls, the most intensive growth is observed at the age of 9-11.
Results and conclusions. The female students were not found to have any significant alternations in the growth of these parameters, since, basically, the process of their physical development, running in parallel with their physical fitness training, comes to an end, however, it depends on the peculiarities of organization of physical education classes for student youth. 

Keywords: physical development, physical fitness, monitoring, preschoolers, school students, students.
