Abstract: Ontogenetic motor development is largely dependent on the location and time of exercise. If the development of motor skills is hindered, for example, by a small space or by the lack of an incentive and a coordinator, the deficit of movements will have repercussions on the whole development of the child, because, among other things, movement is an important means of enriching knowledge. Introduction The function of improving physical development is part of the category of specific functions and has a priority role, especially in the physical education of the young generation. The positive role of harmonious physical/bodily development, of superior somatic/morphological and functional/ physiological indices, for the life and activity of people of all ages is too well known, not being denied or contested. [2], [3]. Physical development is one of the most important components in the field, directly related to a priority goal: improving human development. The aim is, on this level, to obtain superior and harmonious indices, in optimal correlation with the age of the subjects. The improvement of these indices through the activities of physical education and sports is possible - but only within certain limits - if it is acted systematically not only through lessons, but also through the independent activity in the free time of the subjects.[1], [4] Matherial and method The research took place during the school year 2021 - 2022 at the Gymnasium School No. 1 Vicovu de Sus, Suceava County, the subjects subject to research being represented by students of grades I - IV, girls and boys. The school does not have a gym or a specially designed space for physical education classes in bad weather (low temperatures during the cold season or rain). They take place in students' classrooms in makeshift spaces. The experiment group consisted of: - 18 students enrolled in the first grade (9 girls și 9 boys); - 17 students enrolled in the second grade (7 girls și 10 boys);
